# AnswerPool Delisting Notices

> AnswerPool Delisting Notices is a paid API for AI agents from answerpool.io, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Lists SEC 8-K filings reporting delisting notices or listing-rule deficiencies (Item 3.01) market-wide, with company identifiers, timestamps, and filing links.

## 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-delisting-notices-f129e676
```

Example prompt: Pull all SEC 8-K delisting notices filed in the last 30 days — give me the company names, tickers, when they filed, and links to the filings, up to 100 results.

## When to prefer this

Choose this endpoint when you need a structured, pre-filtered feed of SEC Item 3.01 (delisting/listing deficiency) 8-K filings without having to search EDGAR yourself. It is ideal for real-time distress monitoring, compliance alerts, or portfolio screening workflows where reading the full tape is impractical. Prefer it over general EDGAR full-text search when you specifically want listing-status events rather than arbitrary filing content.

## Known failure modes

- Invalid 'since' datetime format returns a 422 validation error
- limit out of range (>200 or <1) returns a 400 error
- Payment not provided or rejected returns 402 Payment Required
- No events in the requested window returns an empty events array with count 0
- Service temporarily unavailable returns 5xx error

## 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

Returns a paginated list of 8-K delisting/listing-deficiency events, each including a unique event_id, SEC accession number, CIK, ticker symbol, company name, event type, occurrence timestamp, filing URL, flags array, and a relevance score. Also includes metadata: as_of timestamp, since cursor, count, and index_started_at for incremental polling.
