## 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 script-master-labs-sec-13f-filing-lookup-169bb518
```

Example prompt: Can you pull up the SEC 13F institutional holdings filing for Berkshire Hathaway? Their CIK is 0001067983.

## When to prefer this

Use this endpoint when you need programmatic, pay-per-call access to SEC 13F institutional holdings data without managing SEC EDGAR API credentials or rate limits yourself. Ideal for agents that need on-demand financial disclosure lookups settled in crypto (USDC on Base) rather than traditional API key billing.

## Known failure modes

- Invalid or non-existent CIK returns no results or an error
- Institution name not found if spelling doesn't match SEC records
- Institution has not filed a 13F (e.g., not a qualifying institutional investment manager)
- Payment failure via x402 if wallet has insufficient USDC balance
- Rate limiting or service unavailability on the render.com host

## 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 13F filing data for the specified institution, including reported equity holdings, share quantities, market values, and other disclosures as submitted to the SEC EDGAR system. Each call costs $0.25 USDC settled on Base via x402.
