## 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 scriptmasterlabs-sec-13f-holdings-lookup-cec22367
```

Example prompt: Pull the SEC 13F institutional holdings filing for Berkshire Hathaway — I want to see what they've reported owning.

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to SEC 13F institutional holdings data via crypto micropayment (USDC on Base), especially in agentic or automated workflows where traditional API key management is impractical. Useful for compliance research, investment due diligence, and portfolio transparency analysis without a subscription.

## Known failure modes

- Invalid or unknown CIK number returns an error or empty result
- Institution name not matched returns no filing data
- SEC EDGAR data unavailable or throttled causes upstream failure
- Payment not completed via x402 or API key returns HTTP 402
- Playground endpoint required for testing without payment

## How this service works

Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

## Output

Returns SEC Form 13F filing data for the queried institution, including reported equity holdings, position sizes, and filing metadata such as reporting period and manager details, sourced from SEC EDGAR disclosures.
