## 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 pocket-network-sec-13f-holdings-lookup-5976fce0 -d '<json body>'
```

Example prompt: Pull the latest SEC 13F institutional holdings for BlackRock — I want to see the full list of issuers, CUSIPs, share counts, and USD values from their most recent quarterly filing. Their ticker is BLK.

## When to prefer this

Use this endpoint when you need structured, machine-readable SEC 13F institutional holdings data keyed by company ticker or CIK, and want a pay-per-call model with no API key or account setup. Ideal for agents doing one-off or infrequent lookups of institutional positions without committing to a subscription data provider. Preferred over scraping SEC EDGAR directly due to the pre-parsed JSON output.

## Known failure modes

- Unknown or invalid ticker/CIK returns an error or empty holdings
- Filer has not submitted a 13F (e.g. not an institutional investment manager) — returns no data
- Quarter with no filing available returns empty or error response
- USDC payment failure or insufficient funds causes request rejection
- Rate limiting or network issues from Pocket Network infrastructure

## How this service works

Pay-per-call access to Pocket Network services. No account, no API key.

## Output

A JSON object containing the filer's complete 13F holdings for the relevant quarter, including each position's issuer name, CUSIP identifier, USD market value, and share count, structured as a single flat or nested JSON document deterministic per filing cycle.
