Endpoint
POSThttps://mesh.heurist.xyz/x402/solana/agents/SecEdgarAgent/institutional_holdersWhen to prefer
Use this endpoint when you need structured, authoritative institutional ownership data sourced directly from SEC 13F regulatory filings. Prefer this over Twitter sentiment or market data endpoints when the user wants verified, official ownership positions rather than inferred or real-time estimates. Best for equity research, due diligence, or tracking large institutional moves.
Side effects
- Unknown or misspelled issuer name returns no results or an error
- Issuer not found in SEC EDGAR 13F dataset (e.g. private company or foreign issuer)
- Data may lag by one quarter since 13F filings are filed 45 days after quarter-end
- Rate limiting or payment failure returns 402 or 429 error
