Corporate Actions API (Splits & Mergers)

Q: What action types does this API cover?

The API covers eight distinct action types: dividend (cash and stock distributions), split (forward and reverse splits), merger (company combinations), acquisition (buyouts), spinoff (subsidiary separations), bankruptcy (Chapter 11 and Chapter 7 filings) and delisting (exchange removals). Pass action=all or omit the parameter to return every type.

Q: What does the value field represent for each action type?

The meaning of value depends on the action type. For dividends, it is the per-share cash amount in USD. For splits, it is the split ratio — a value of 4 means a 4-for-1 forward split; a value of 0.5 means a 1-for-2 reverse split. For action types where no numeric value is relevant (mergers, bankruptcies, delistings), the field returns null.

Q: Can I query market-wide corporate actions without specifying a ticker?

Yes. Omit ticker and provide any other filter — action, period, or from_date — to retrieve actions across all companies. For example, action=bankruptcy&period=ytd returns all bankruptcy filings year-to-date for every company in the database. Use the limit parameter (up to 10,000 per page) and paginate with page for large result sets.

Q: Can I combine period and from_date in the same request?

No — they are mutually exclusive. Use period for relative lookbacks (e.g., 1y, ytd) and use from_date with optional till_date when you need a specific calendar range. If both are supplied, period takes precedence and from_date is ignored.

Related endpoints: Pair with the Dividends API for daily yield time-series and per-share payment history. Use the Financial Statements API to assess financial health around merger or bankruptcy events.

1. Endpoint & Parameters

At least one filter must be provided with every request — ticker, related_ticker, action, period, or from_date. Multiple filters are combined with AND logic. Results are sorted newest-first and paginated.

4. Use Cases

Corporate actions data underpins back-testing accuracy, deal tracking, and event-driven research. These are the most common workflows built on top of this endpoint.

Price History Adjustment

Pull all historical splits for a ticker via action=split&period=max and use the value ratios to back-adjust raw OHLCV data from the Stock Quotes API. This is the foundation of any accurate long-term back-test.

M&A Deal Pipeline Monitoring

Query action=merger,acquisition&period=ytd without a ticker to get a running market-wide deal log. Pair with related_ticker to track every acquisition made by a specific acquirer over time.

Dividend Calendar

Retrieve action=dividend for a basket of tickers to build a forward-looking ex-dividend calendar. The value field returns the per-share dividend amount for each payment, ready for income projection models.

Event-Driven Strategy Research

Use action=spinoff&period=5y to study post-spin-off performance patterns. Combine the effective date from this API with price data from the Quotes API to measure announcement-day returns and N-day drift.

Distressed Asset Screening

Query action=bankruptcy&period=2y to build a dataset of recent Chapter 11 and Chapter 7 filings. Cross-reference against Institutional Ownership data to identify which funds were exposed at the time of filing.

Universe De-listing Cleansing

Pair action=delisting&period=max with the Stock Ticker List API to identify and remove de-listed tickers from back-test universes — the key step in eliminating survivorship bias.

Multi-ticker queries

Pass a comma-separated list to ticker (e.g., ticker=AAPL,MSFT,GOOGL) to retrieve corporate actions for an entire portfolio in a single call. The response metadata block will not include ticker or name in multi-ticker mode — use the per-row ticker field to identify each record.

Frequently Asked Questions

What action types does this API cover?

The API covers eight distinct action types: dividend (cash and stock distributions), split (forward and reverse splits), merger (company combinations), acquisition (buyouts), spinoff (subsidiary separations), bankruptcy (Chapter 11 and Chapter 7 filings) and delisting (exchange removals). Pass action=all or omit the parameter to return every type.

What does the `value` field represent for each action type?

The meaning of value depends on the action type. For dividends, it is the per-share cash amount in USD. For splits, it is the split ratio — a value of 4 means a 4-for-1 forward split; a value of 0.5 means a 1-for-2 reverse split. For action types where no numeric value is relevant (mergers, bankruptcies, delistings), the field returns null.

Can I query market-wide corporate actions without specifying a ticker?

Yes. Omit ticker and provide any other filter — action, period, or from_date — to retrieve actions across all companies. For example, action=bankruptcy&period=ytd returns all bankruptcy filings year-to-date for every company in the database. Use the limit parameter (up to 10,000 per page) and paginate with page for large result sets.

What is the `related_ticker` field used for?

It identifies the counterparty company in actions that involve two entities. In a merger or acquisition, related_ticker is the acquirer. In a spin-off, it is the parent company that separated the subsidiary. You can also filter by related_ticker to find all deals where a specific company acted as the acquirer, which is useful for building acquisition history timelines for large conglomerates.

Can I combine `period` and `from_date` in the same request?

No — they are mutually exclusive. Use period for relative lookbacks (e.g., 1y, ytd) and use from_date with optional till_date when you need a specific calendar range. If both are supplied, period takes precedence and from_date is ignored.

Is the Corporate Actions API free to use?

Yes, the Corporate Actions API is free to use. Sign up for an API key and start pulling splits, dividends, mergers, and other corporate actions immediately — no credit card required.
