## 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 agentfund-sec-13f-institutional-holdings-f740cb35 -d '<json body>'
```

Example prompt: Pull the latest SEC 13F institutional holdings for Berkshire Hathaway — give me the top 50 positions they reported.

## When to prefer this

Use this endpoint when you need structured, parsed 13F holdings data for a specific institutional filer identified by ticker or CIK, without having to parse raw EDGAR XML yourself. Prefer this over SEC Full-Text Filing Search when you want clean tabular holdings data rather than raw document text, and over general financial APIs when you need SEC-sourced regulatory disclosure data specifically.

## Known failure modes

- Unknown ticker or CIK returns empty or error response
- Limit outside 1-200 range may be rejected or clamped
- Fund has not filed a 13F (e.g. too small or foreign)
- EDGAR data may lag actual filing date by hours
- Payment failure if USDC balance is insufficient for $0.02 fee
