## 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-13d-g-filing-lookup-d2da88d6
```

Example prompt: Pull the last 5 SEC Schedule 13D and 13G filings for TSLA so I can see who's disclosed significant ownership stakes recently.

## When to prefer this

Choose this endpoint when you need to surface beneficial ownership disclosures (Schedule 13D/13G) filed with the SEC for a specific publicly traded company. Ideal for activist investor research, M&A due diligence, compliance checks, or tracking large institutional stakes. Prefer this over general financial data APIs when you specifically need the raw SEC filing metadata rather than aggregated ownership data.

## Known failure modes

- Invalid or unrecognized ticker symbol returns empty results or error
- Limit parameter outside 1–20 range returns a validation error
- Ticker not found on SEC EDGAR returns empty filing list
- Payment not provided or invalid returns HTTP 402 requiring x402 micropayment
- Rate limiting or upstream SEC EDGAR downtime may cause timeouts

## 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 a list of SEC Schedule 13D and 13G filings for the requested ticker, including details such as filer name, ownership percentage, filing date, and whether the filing is an initial report or amendment. Defaults to 10 results, up to 20 per call.
