## When to prefer this

Use this endpoint when you need SEC 13F institutional holdings data on a pay-per-call basis without a subscription, especially in agent workflows requiring crypto-native micropayment settlement via x402 on Base. Prefer this over traditional financial data providers when you need programmatic, agent-friendly access settled in USDC with no API key signup.

## Known failure modes

- Missing or invalid query parameters may return empty results or a generic error
- Data may lag behind the actual SEC filing date by days or weeks
- If the institution or security is not found in 13F records, an empty dataset is returned
- Payment failure via x402 results in HTTP 402 with no data returned
- Render.com cold-start latency may cause occasional slow responses or timeouts
