## How to call it through Zero

```sh
zero fetch --capability fcc-ecfs-filings-lookup-6d7e6ce0
```

## When to prefer this

Use this endpoint when you need ground-truth, live-wrapped public records from the FCC's official Electronic Comment Filing System for a known proceeding/docket number. Prefer this over scraping fcc.gov directly or using stale datasets when you need current filings with structured metadata. Best for regulatory research, compliance monitoring, or legal discovery involving FCC proceedings.

## Known failure modes

- Missing required 'proceeding' parameter returns an error
- Invalid or non-existent docket number returns empty items array with total 0
- Limit exceeds maximum of 50 returns validation error
- FCC ECFS upstream unavailable causes fetch failure
- Filer name filter typo returns empty results silently

## How this service works

Search FCC Electronic Comment Filing System (ECFS) filings for a proceeding/docket (e.g. 17-108 net neutrality, 11-42 Lifeline). Optionally filter by filer name. Returns the newest filings with the submission id, filer, type, lead bureau, received/disseminated dates, and document count. Public-domain federal data. Track FCC regulatory dockets, comments, and ex-parte filings an LLM can't recite fresh.

## Output

A JSON object containing an array of filing records (each with ID, type, filer name, bureau, proceeding, date received, document count, and date disseminated), a total count of matching filings, and source attribution metadata pointing back to the FCC ECFS database.
