Getting Started
Alphanume exposes every dataset through a single, query-parameter–based REST API. This page walks through account setup, authentication, and the request pattern shared by all endpoints.
Create an Account
To access the Alphanume API, create an account at the sign-up page. After registering and setting your password, your API key will be emailed to you automatically.
Base URL
All Alphanume API requests are made against:
https://api.alphanume.com/v1Example Request
The API follows a simple, query-parameter–based request structure. Below is a sample request to the Historical Market Cap endpoint:
import requests
url = "https://api.alphanume.com/v1/historical-market-cap"
params = {
"ticker": "AAPL",
"date": "2026-02-06",
"api_key": "alp_abc123"
}
response = requests.get(url, params=params)
data = response.json()
print(data)curl "https://api.alphanume.com/v1/historical-market-cap?ticker=AAPL&date=2026-02-06&api_key=alp_abc123"Header-Based Auth
You can also pass your API key via the X-API-Key header instead of a query parameter.
curl "https://api.alphanume.com/v1/historical-market-cap?ticker=AAPL&date=2026-02-06" \
-H "X-API-Key: alp_abc123"Response Format
Responses are returned in JSON and are designed to be immediately usable in research pipelines.

Next-Day Movers
The Next-Day Movers dataset provides a daily, model-ranked collection of equities most likely to experience large price moves in the following trading session.
Each observation contains one of the top names selected from a universe of liquid optionable equities, based on a predictive model designed to identify securities with elevated next-day realized movement potential. Behind the scenes, the model evaluates features such as implied volatility, realized volatility, and related volatility structure information to rank candidates by expected next-day movement.
All observations are stored historically and remain fixed once published, allowing the dataset to be used safely in systematic research and backtesting workflows without lookahead bias.
Why it's useful
- Identify equities most likely to experience outsized next-day moves
- Build directional or non-directional volatility trading strategies
- Screen for high-movement candidates before the next session opens
- Study the relationship between implied volatility, realized volatility, and future movement
- Backtest systematic workflows built around next-day mover selection

Quant Galore Momentum Index
The Quant Galore Momentum Index provides the historical and live constituents of a rules-based, cross-sectional equity momentum strategy.
Each observation represents a stock included in the 10-stock monthly basket on a specific rebalance date, along with its rank within that basket. This dataset is designed for systematic traders, researchers, and allocators who want clean, point-in-time access to a maintained momentum index without reconstructing the full ranking pipeline.
Why it's useful
- Replicate or track the Quant Galore Momentum strategy
- Run independent performance attribution or turnover analysis
- Study cross-sectional momentum concentration effects
- Measure post-rebalance drift and decay
- Build overlays (options, hedging, leverage) on top of a rules-based equity core
Index Overview
- Universe: Deeply liquid U.S. equities with at least six consecutive weeks of listed weekly option expirations
- Construction: Cross-sectional momentum ranking
- Basket Size: Top 10 stocks
- Rebalance Frequency: Monthly
- Ranking: Highest momentum = rank 1
The dataset reflects the actual basket at that specific date, not a reconstructed or retroactively altered list.

S&P 500 0-DTE Strike Band
ProThe S&P 500 0-DTE Strike Band dataset provides a daily, model-derived strike range representing the expected intraday price bounds for the S&P 500 index during the current trading session.
Each observation contains a lower and upper strike level that define the range in which the index is expected to remain with high probability through the close of the same-day (0-DTE) options cycle. The band is calculated using forward-looking implied probability distributions and broader market risk factors, and is designed to assist traders in strike selection and risk management for intraday option strategies.
All observations are point-in-time and stored historically. Once published, values are never retroactively altered, allowing the dataset to be used safely in systematic research and backtesting workflows.
Why it's useful
- Identify statistically informed strike levels for same-day SPX options
- Structure intraday spreads, condors, or volatility-selling strategies
- Quantify expected index movement using implied probability information
- Filter or validate discretionary strike selection decisions
- Analyze historical containment probabilities for intraday index ranges

Strike Band Definition
The lower_strike and upper_strikevalues represent the model-derived strike range within which the S&P 500 index is expected to remain through the close of the same-day options session. The band is calculated using forward-looking implied probability distributions, realized volatility data, and broader market risk factors. Strikes are rounded to the nearest listed SPX option increment.

S&P 500 Risk Regime
The S&P 500 Risk Regime dataset provides a daily, point-in-time binary classification of prevailing equity market conditions.
Each observation reflects whether the S&P 500 was classified as being in a risk-off (1) or risk-on (0) regime on that date. The dataset is designed for systematic traders and researchers who require a stable, reproducible market state signal for filtering, sizing, or regime-aware modeling.
Why it's useful
- Filter strategies during elevated volatility or selloff regimes
- Dynamically scale position size based on market conditions
- Improve risk-adjusted returns via regime-aware allocation
- Segment backtests into bull vs stress environments
- Study behavioral or factor performance across volatility states

Regime Definition
1 → Risk-Off: elevated volatility and/or stress conditions. Historically associated with defensive positioning and higher downside risk.
0 → Risk-On: lower volatility and constructive equity conditions. Historically associated with trend persistence and risk-seeking behavior.
The classification is derived from forward-looking implied volatility metrics and is stored as a fixed daily regime label. Historical values are not retroactively altered.

IV/HV Rank (52-Week)
The IV/HV Rank dataset answers is volatility high or low for this name?For each ticker and trading day it places the current ~30-day implied vol and 30-day realized vol within that name's own trailing 52-week (strict 252-observation) range, as both a 0–100 rank and a 0–100 percentile.
Rank measures position within the year's high–low band; percentile measures the share of the trailing year that traded below the current value:
*_rank=(value − 52w_low) / (52w_high − 52w_low) × 100*_percentile= share of trailing-year observations below the current value × 100
The dataset is derived from the same iv/hv series as IV/HV Premium, over the same universe and update cadence. A ticker appears only once it has a full year of history; daily cross-sectional rank and z-score fields add context against the rest of the universe.
Why it's useful
- Find names whose implied vol is historically cheap (low IV Rank) or expensive (high IV Rank) for premium timing
- Compare IV Rank against HV Rank to spot where implied is stretched relative to a name's own realized regime
- Screen for high-percentile vol candidates with
min_iv_percentile - Build mean-reversion or breakout signals on a name-relative, point-in-time vol measure

}Notes on Data Behavior
- A ticker appears only once it has a full year (252 observations) of
iv-hv-premiumhistory - Today's row is provisional intraday (
is_final = 0) and settled after the close (is_final = 1, ~16:30 ET) - Rank uses the high–low band; percentile uses the share of the trailing year below the current value

Vol-of-Vol Index
The Vol-of-Vol Index answers whose volatility is most unstable? For each ticker and trading day it measures the coefficient of variation (standard deviation ÷ mean) of that name's own ~30-day implied vol and 30-day realized vol over a trailing 21 observations (~1 month). Higher values mean the name's volatility is itself more variable.
The measure is dimensionless, so it is directly comparable across names, and a daily cross-sectional ranking surfaces the most vol-unstable names on any given day. It is derived from the same iv/hv series as IV/HV Premium, over the same universe and update cadence.
The first ~month of each ticker's history is absent while the 21-observation window warms up.
Why it's useful
- Rank the universe by which names have the most unstable implied or realized vol on a given day
- Filter for stable-vol names (low vol-of-vol) when a strategy depends on a steady vol regime
- Flag names whose vol is churning ahead of catalysts or regime shifts
- Combine with IV/HV Premium and IV/HV Rank for a fuller picture of a name's vol behavior

Earnings Implied vs Realized
The Earnings Implied vs Realized dataset is a per-ticker track record of how each company's earnings move was priced versus how it actually moved. For every earnings event, it captures the pre-earnings at-the-money straddle (the market's implied move) and compares it to the realized post-earnings move.
Alongside each event it carries running, point-in-time statistics for the ticker — how often the straddle over- or under-priced the move, and the trailing averages of implied move, realized move, and over/under-pricing. This answers the recurring question: does this name usually over- or under-price its earnings?
All observations are stored historically and remain fixed once the post-earnings session has resolved, so the dataset can be used safely in systematic research and backtesting without lookahead bias.
Why it's useful
- Answer “does TICKER usually over- or under-price its earnings?” with a running hit rate
- Rank or screen names by their straddle over/under-pricing tendency ahead of an earnings season
- Study the implied-vs-realized edge for earnings vol selling or buying
- Backtest earnings strategies conditioned on a ticker's historical move ratio and hit rate
- Compare straddle-implied moves to consensus EPS surprises and realized reactions

- Updated daily after the market close (EOD)
- For an event whose post-earnings session has not yet closed, the realized fields (
realized_return_pct,realized_abs_move_pct,over_under_pct,move_ratio,overpriced) are not yet populated - Running statistics (
n_events_to_date,hit_rate_to_date, the trailing averages) are point-in-time — they reflect only events up to and including each row - Once an event resolves, its values are fixed and not retroactively altered

Stock Dilution
The Dilution dataset captures U.S. equity dilution risk at the moment it enters the market. It is a point-in-time record of S-1 registration statements, enriched with market context and lifecycle tracking, designed for traders and researchers who need to identify and manage dilution-driven risk with precision.
Each record represents a filing as it was known on the filing date, labeled for its dilutive impact and later resolved as the filing becomes effective or is withdrawn.
Why it's useful
- Identify dilution risk at inception, not in hindsight
- Filter or size exposure around secondary offerings and resale pressure
- Build short-biased or risk-aware strategies in small- and mid-cap equities
- Study post-filing outcomes, including time-to-effectiveness or withdrawal

De-SPAC Events
The De-SPAC Events dataset provides a point-in-time record of completed de-SPAC transactions, identifying when special purpose acquisition companies (SPACs) formally consummate their business combinations and transition into operating companies.
Each observation represents a confirmed de-SPAC completion event derived from SEC filings (typically Super 8-K disclosures). These events mark the structural transition from a blank check company into a publicly traded operating entity.
All observations are stored historically and remain fixed once published, allowing the dataset to be used safely in systematic research and backtesting workflows without lookahead bias.
Why it's useful
- Identify newly public companies emerging from SPAC mergers
- Build event-driven strategies around post de-SPAC performance
- Study structural inefficiencies following SPAC business combinations
- Track regime shifts in liquidity, float, and ownership post-merger
- Construct short-bias or mean-reversion strategies targeting de-SPAC cohorts
- Backtest systematic workflows conditioned on corporate transition events

Dataset Definition
Each observation corresponds to a confirmed de-SPAC completion event, identified through systematic parsing of SEC filings. A de-SPAC event is defined as the consummation of a business combination in which a SPAC merges with or acquires an operating company and ceases to function as a shell entity.
Events are primarily sourced from filings that explicitly indicate completion of the transaction, including language such as:
- “consummated the business combination”
- “completion of the business combination”
- “closed the business combination”
Additional confirming signals may include change in shell-company status, name change following the transaction, and commencement of trading under a new ticker. Only filings that clearly indicate completion (not proposals or pending transactions) are included.
Notes on Data Behavior
- Events are recorded using the filing date of the de-SPAC completion disclosure
- This date may occur shortly after the first day of trading under the new ticker
- Observations are point-in-time and reflect only information available at the time of filing
- Historical records are not retroactively altered
- Dates are returned as
YYYY-MM-DD - Results are ordered by
date DESC
Corporate Default Events
The Corporate Default Events dataset provides a historical, point-in-time log of public-company default events, labeled from SEC filing text and normalized into a clean event feed.
Each observation represents a date where a company was flagged as being in default status (is_default = 1), along with the associated ticker and the SEC filing URL used as source evidence.
The dataset is designed for systematic traders and researchers who need a reproducible event series for distress screens, event studies, short baskets, and credit-risk proxies.
Why it's useful
- Build distress / default event studies and measure post-event drift
- Screen for credit-like equity behavior without requiring CDS data
- Create short candidate universes based on documented default status
- Filter long strategies to avoid names entering default or restructuring conditions
- Train ML models using default events as labels or regime triggers

Dividend Capture
The Dividend Capture dataset is a calendar-driven view of ex-dividend events. For each event it measures how much the stock dropped on the ex-date relative to the dividend paid (the drop ratio), the net amount captured after that drop, and how many trading days the position took to recover back to breakeven.
Historical ex-day behavior is joined to the forward ex-dividend schedule, so the same endpoint answers both “how have ex-days behaved for this name?” and “which dividends are coming up?” — a ready-made dividend-capture screen.
Why it's useful
- Run a ready-made dividend-capture screen across upcoming ex-dividend dates
- Gauge how much of the dividend is typically given back via the ex-day price drop
- See historical recovery odds (within 1 / 3 / 5 / 10 / 20 trading days) before committing capital
- Pull a forward ex-dividend calendar for a single name or the whole market
- Filter to events that did or did not recover to breakeven for post-trade analysis

Date Filtering
All dates must be provided in YYYY-MM-DD format. Supported parameters:
date_gtedate_ltedate_gtdate_lt
Any logically valid combination is accepted. Note that the forward edge of range queries is always capped at today + future_days, so an open-ended or forward-looking range will not return months of un-actionable future ex-dates. Past-only queries are unaffected.

Historical Optionable Tickers
The Historical Optionable Tickers dataset captures the point-in-time universe of U.S. equities with listed options chains.
It is a monthly snapshot of stocks with available options contracts, enriched with structural expiration information to help traders construct optionable universes with precision. Each record reflects the option listing structure as it existed on the first trading day of the respective month.
Why it's useful
- Construct historically accurate optionable universes
- Filter equities by expiration density (weekly vs non-weekly structures)
- Study the evolution of options availability over time
- Backtest strategies that require confirmed option chain presence
- Identify securities with robust weekly expiration coverage
This dataset is especially useful for systematic traders who need to avoid survivorship bias in options-based research.
Snapshot Methodology
- Snapshots are taken on the first trading day of each month
- Each snapshot reflects listed option expirations available at that time
- Historical records correspond to the first trading day of their respective month
- Records are point-in-time and do not retroactively change

Field Definitions
avg_days_between represents the average number of days between the next six consecutive option expiration dates after the first week window (expirations 1 through 6). Values close to 7 indicate dense weekly expiration structures; higher values indicate less frequent expiration spacing (e.g., biweekly or monthly listings).
has_weeklies is a binary indicator: 1 means multiple consecutive weekly expirations were listed at the snapshot date; 0 means weekly expiration continuity was not present.
Pagination
The Optionable Tickers endpoint uses cursor-based pagination for efficient retrieval of large result sets. Results are ordered deterministically:
ORDER BY date DESC, ticker DESCWhen paginating, you must provide both cursor_date and cursor_ticker. These must match the next_cursor object from the previous response. If only one cursor field is provided, the request returns a 400 error.
Notes on Data Behavior

Ticker Classification
The Ticker Sector & Industry Classification dataset provides a mapping of equity tickers into Alphanume-defined sector and industry groups.
Each observation assigns a ticker to a consistent, internally defined classification system derived from underlying business activity. These classifications are designed for quantitative workflows and are not intended to replicate standardized taxonomies.
The dataset is structured to be stable, URL-safe, and directly queryable for use in filtering, grouping, and feature engineering pipelines.
Why it's useful
- Filter universes by sector or industry exposure
- Build sector-neutral or industry-relative strategies
- Group tickers for cross-sectional analysis
- Construct features based on economic exposure
- Standardize classification across research pipelines
- Join with other datasets for consistent segmentation

Notes on Data Behavior
- Classifications are deterministic and consistent
- Values are not dynamically inferred at query time
- Results are ordered by ticker (ascending)
- No date dimension is applied
- The dataset represents the current mapping of tickers to classifications
Historical Market Cap
The Historical Market Cap dataset provides point-in-time market capitalization and shares outstanding for equities, as they were known on each historical date.
It is designed for research and production workflows that require true point-in-time fundamentals (e.g., avoiding lookahead bias when modeling size, liquidity regimes, or dilution / float dynamics).
Why it's useful
- Build point-in-time size factors (market cap) without future leakage
- Normalize signals by shares outstanding / float regime
- Backtest strategies that depend on historical capitalization thresholds (e.g., “only trade > $X market cap at the time”)
- Monitor structural shifts from issuance / buybacks via share count changes

}Pagination
The Historical Market Cap endpoint uses cursor-based pagination for efficient retrieval of large result sets. Results are ordered deterministically:
ORDER BY date DESC, ticker DESCEach response includes:
count— number of rows returned in this pagehas_more— whether additional data is availablenext_cursor— cursor object to retrieve the next page
When paginating, you must provide both cursor_date and cursor_ticker. These must match the next_cursor object from the previous response. If only one cursor field is provided, the request returns a 400 error.

print(f"Retrieved {len(all_rows)} rows.")Wikipedia Views
ProThe Wikipedia Views dataset provides daily Wikipedia page view counts for equities, along with rolling 30-day statistics (mean, standard deviation, and z-score) measuring how unusual current attention is relative to the recent baseline.
It is designed for research and production workflows that incorporate retail attention as a feature — whether as a standalone signal, a regime filter, or an input to event-driven and cross-sectional models.
Why it's useful
- Build attention-based factors that capture shifts in investor interest before they show up in price or volume
- Detect anomaly days where ticker-level attention deviates sharply from its 30-day baseline (high z-score events)
- Filter or contextualize event-driven setups (earnings, news, filings) by the level of public attention surrounding them
- Backtest strategies conditioned on attention regimes (e.g., “only trade names with
zscore_30d > 2”)

}SEC Filing Intensity
ProThe Filing Intensity dataset provides daily SEC filing counts per equity, capturing how actively a company is interacting with the SEC on any given day. Filing activity is a leading indicator: corporate actions, capital raises, insider activity, and material events all leave fingerprints in the EDGAR filing stream before they're priced in.
It is designed for research and production workflows that incorporate corporate filing behavior as a feature — whether as a standalone signal, an event-detection trigger, or an input to event-driven and cross-sectional models.
Why it's useful
- Detect spikes in corporate activity that often precede material announcements, capital structure changes, or insider transactions
- Build event-driven signals around tickers entering periods of unusually heavy SEC engagement
- Filter or rank universes by recent filing intensity to surface names with active corporate developments
- Backtest strategies conditioned on filing-burst regimes (e.g., “only trade names with
filing_count >= 5on a given day”)
