How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://rag-diet.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a 'data' field containing distilled 13F institutional filing information for the requested ticker, a 'status' field ('ok'), and an 'roi_proof' object that includes a compression_ratio_pct showing how much the context was compressed (e.g. 91.4% compression). Payment is settled in USDC on Base via x402.
Example use cases
Hedge fund position research for a stock
“Can you get me the 13F institutional holding data for Tesla — I want to know which major funds are holding it right now?”
Pre-earnings institutional sentiment check
“Before MSFT earnings, pull the latest 13F data for Microsoft so I can see how institutional positioning looks.”
Small-cap institutional ownership scan
“Look up the 13F filings for AMD and give me a distilled view of who the top institutional holders are.”
Technical details
Endpoint
GEThttps://rag-diet.agentdiet.dev/v1/institutional-13f?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need token-efficient, compressed institutional 13F ownership data for a specific stock ticker and want a machine-readable output with a verifiable compression ratio. Useful for agents operating under strict context-window budgets that still need institutional holding intelligence. Choose this over raw SEC EDGAR scraping when you want pre-distilled, structured output without bloat.
Side effects
- Missing or invalid ticker symbol returns empty or error data
- Unknown ticker with no 13F filings returns empty data object
- Payment not settled (x402 402 response) if USDC not provided
- Rate limiting or node unavailability may cause non-200 responses
- Stale filing data if 13F source has not been updated post-quarterly filing deadline
