# AnswerPool Rule Impact Map

> AnswerPool Rule Impact Map is a paid API for AI agents from answerpool.io, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Maps a Federal Register rule to the public companies whose SEC filings cite its docket, RIN, or CFR part, ranked by citation strength with filing counts and dates.

## 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-rule-impact-map-bd2e3fc0
```

Example prompt: Which public companies cite Federal Register rule 2026-12341 in their SEC filings? Show me up to 50 companies ranked by citation strength, looking back over the past two years.

## When to prefer this

Use this endpoint when you need to cross-reference a specific federal rule with its actual footprint in public company SEC disclosures in a single call, rather than querying Federal Register and EDGAR separately and joining results yourself. Prefer it over the CFR Citers endpoint when you have a Federal Register document number rather than a CFR title/part, and over the Company Regulation Radar endpoint when you want company-level impact across the full market for one rule rather than rules mapped to one company.

## Known failure modes

- Invalid or malformed document_number returns a validation error
- Document number not found in Federal Register yields zero company matches
- lookback_days outside 30–1825 range returns a parameter error
- limit outside 1–100 range returns a validation error
- No SEC filings reference the rule in the specified lookback window — returns empty companies array with count 0

## 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 ranked list of public companies whose SEC filings reference the specified Federal Register rule, including each company's CIK, name, number of matching filings, form types, latest filing date, and which identifiers (docket, RIN, CFR part) were matched — plus rule metadata (title, agencies, publication date, significance flag) and a total filing match count.
