## When to prefer this

Use this endpoint when you need to discover what SEC filing types are available before constructing a query for specific filings or financial documents. It acts as a metadata/reference endpoint to enumerate valid form type codes prior to fetching actual filing data.

## Known failure modes

- 402 Payment Required if USDC payment not included
- Invalid or missing x402 payment header returns payment error
- Network timeout returning empty or partial response
