## 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 sec-edgar-ticker-cik-lookup-fd0bf46f
```

Example prompt: Can you find Apple's SEC EDGAR CIK number and exchange listing? Search for 'apple' and return up to 5 results.

## When to prefer this

Use this endpoint as the first step when you need any SEC EDGAR data for a company but only have a ticker or name — it resolves identifiers needed for all downstream EDGAR queries. Prefer this over direct CIK guessing or manual EDGAR web searches. It requires no API key or account, charges only $0.001 USDC per call, and errors are not billed.

## Known failure modes

- No results found for obscure or private companies not registered with SEC
- Query matches too many companies — use more specific name or ticker for precise results
- Rate limiting from SEC EDGAR upstream causing delayed or empty responses
- Invalid or malformed query string returns empty results set
- Private companies, LLCs, and foreign private issuers may not appear or have incomplete data

## How this service works

SEC EDGAR data for AI agents, paid per call in USDC via x402 (no account, no API key): ticker/CIK lookup, company profiles, recent filings (10-K, 10-Q, 8-K, Form 4…) with document links, key annual XBRL fundamentals and any XBRL concept time series. Public SEC data, cached, fetched under SEC fair-access rules. Errors are never charged.

## Output

Returns a JSON object with the search query and a list of matching companies, each containing: CIK (integer), company name, ticker symbol, exchange name, and zero-padded CIK string (e.g. '0000320193'). Results are ordered by relevance to the query.
