# AnswerPool M&A Events

> AnswerPool M&A Events is a paid API for AI agents from answerpool.io, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability answerpool-m-a-events-ff0fda98
```

Example prompt: Pull the last 50 completed M&A events from SEC 8-K filings — acquisitions, dispositions, and changes of control — filed since August 17, 2026, and show me the company names, tickers, and filing links.

## When to prefer this

Choose this endpoint when you need unfiltered, market-wide coverage of completed M&A transactions (Items 2.01 and 5.01) from SEC 8-K filings without pre-filtering by company or sector. It is ideal for deal-monitoring workflows that require a continuous, paginated feed of all acquisition, disposition, and change-of-control events across the entire market. Prefer it over full-text EDGAR search when you want structured, pre-classified event data with tickers and direct filing links rather than raw filing matches.

## Known failure modes

- Invalid since value (non-ISO string) returns a 422 validation error
- limit outside 1-200 range returns a 400 or 422 error
- No events in the requested window returns count=0 and empty events array
- Payment not included or invalid x402 payment returns 402 Payment Required
- Rate limiting or service unavailability returns 429 or 503

## How this service works

AnswerPool turns SEC EDGAR, the Federal Register, USAspending, NIH, BLS and OpenAlex into structured JSON answers that AI agents and developers fetch in one call. 69 endpoints free, no account; derived analyses $0.02–$0.05 per call by card credits or USDC (x402). MCP server, full provenance.

## Output

A JSON object containing an as_of timestamp, a since cursor, the total count of matching events, and an array of event objects. Each event includes a unique event_id, SEC accession number, CIK, ticker symbol, company name, form type, event_type classification, occurred_at timestamp, flags array, relevance score, a payload with deal-specific details, and a direct URL to the SEC filing. Also includes index_started_at and a next_cursor for pagination.
