How this service works
Attested instrument-identity enrichment for AI agents: map a ticker, ISIN, CUSIP, SEDOL, FIGI, or instrument name to canonical FIGI records (name, security type, market sector, exchange) via Bloomberg open symbology, with provenance (source, retrieval time) attached to every answer. Built for agents that must know WHICH security a claim, order, or document is about before acting on it.
Output
Returns one or more FIGI-matched records, each containing the canonical instrument name, FIGI identifier, security type, market sector, and exchange, plus provenance metadata including the data source and retrieval timestamp for auditability.
Example use cases
Example prompt
“Before I process this trade confirmation, can you resolve 'AAPL' as a ticker to its canonical FIGI record so we know exactly which security we're dealing with — including its security type, market sector, and exchange?”
Technical details
Endpoint
POSThttps://groundcheck.seiche.info/resolveWhen to prefer
Use this endpoint when an AI agent needs to unambiguously identify a financial instrument before acting on a claim, order, or document — especially when provenance (source + retrieval time) must be attached to the answer for auditability. Prefer this over generic search when you need Bloomberg-standard FIGI canonical identity with attested metadata, rather than just name-matching or price data.
Side effects
- Unrecognized or ambiguous identifier returns empty results or low-confidence matches
- Mismatched id_type hint causes lookup failure even for valid identifiers
- Rate limiting or upstream Bloomberg OpenFIGI API unavailability returns 5xx error
- Invalid query string (empty or malformed) returns 400 validation error
- Payment failure via x402 protocol blocks the request before resolution
