## 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 stock-bloc-sec-data-api-eab8f3b3
```

Example prompt: Pull the latest SEC 13F consensus holdings data from Stock Bloc — I want to see which funds are holding the most Amazon and Alphabet shares and what the total position values are.

## When to prefer this

Choose this endpoint when you need aggregated institutional holdings data parsed from SEC 13F filings, particularly to identify consensus positions across multiple funds and total USD exposure. Prefer it over raw EDGAR scraping when you want pre-parsed, structured consensus data with fund counts and valuations in a single API call.

## Known failure modes

- Missing or invalid query parameters returns ambiguous result
- SEC EDGAR upstream unavailability may delay or fail data retrieval
- Ticker symbol may be null for some international or less-tracked securities
- Payment failure via x402/USDC blocks request processing
- Rate limiting if payment is not properly processed
