## Overview

SEC EDGAR is the US Securities and Exchange Commission's full-text search across public company filings. For any US-listed company, EDGAR provides authoritative 10-K (annual report), 10-Q (quarterly), 8-K (current event), and proxy or insider filings.

## When to Choose It

- Choose it for US company research, especially financial history, risk factors, regulatory disclosures, and management discussion.
- Choose it when a query implies a publicly traded US company, such as a ticker, "SEC filing", "10-K", or "earnings report".
- Avoid it for general tech news, academic papers, or non-US companies.

## How To Search

- `api_search` queries `https://efts.sec.gov/LATEST/search-index?q=<query>` and maps `hits.hits[*]._source` into filing evidence. Filing URLs are synthesized from `ciks[0]` and `adsh` to point at the SEC Archives index page for the exact filing.

## Known Quirks

- SEC enforces a User-Agent policy. Every request must carry a contact string or the endpoint may effectively block access.
- The search endpoint returns filing metadata only, not filing-body excerpts. Snippets are synthesized from form type and filing dates.
- Coverage is limited to SEC-registered filers, so pure non-US companies are out of scope unless they file with the SEC.

# Quality Bar

- Evidence items have non-empty title and url.
- No crash on empty or malformed API response.
- Source channel field matches the channel name.
