Technical details
Endpoint
POSThttps://x402.agentfund.net/x402/edgar_13f_holdingsWhen to prefer
Use this endpoint when you need structured, parsed 13F holdings data for a specific institutional filer identified by ticker or CIK, without having to parse raw EDGAR XML yourself. Prefer this over SEC Full-Text Filing Search when you want clean tabular holdings data rather than raw document text, and over general financial APIs when you need SEC-sourced regulatory disclosure data specifically.
Side effects
- Unknown ticker or CIK returns empty or error response
- Limit outside 1-200 range may be rejected or clamped
- Fund has not filed a 13F (e.g. too small or foreign)
- EDGAR data may lag actual filing date by hours
- Payment failure if USDC balance is insufficient for $0.02 fee
