## 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-13f-holdings-filing-lookup-d202f591
```

Example prompt: Pull the latest SEC 13F holdings filing for Bridgewater Associates — use their CIK if you can find it, otherwise search by name.

## When to prefer this

Use this endpoint when you need structured 13F institutional holdings data from SEC EDGAR and want a simple paid API rather than scraping EDGAR directly. Prefer this over raw EDGAR queries when you need quick lookup by manager name (CIK resolution included) or when accessing historical quarterly filings by accession number. Not suitable for real-time market data, non-13F filings, or non-US regulatory filings.

## Known failure modes

- CIK not found or invalid — returns success:false or empty result
- Manager name ambiguous — best-effort resolution may match wrong entity; prefer CIK
- Accession number requires CIK to be supplied together
- Quarter not yet filed or data unavailable — returns no result
- Malformed quarter date format — must be ISO YYYY-MM-DD
- Rate limit or payment failure — 402 response requiring USDC micropayment

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

Returns a JSON object with a 'result' field containing the 13F filing data (holdings, positions, filer details) and a 'success' boolean indicating whether the lookup succeeded. The result structure reflects SEC EDGAR filing contents for the matched manager and quarter.
