Example use cases
Compliance check for cross-border fund holdings
“I need to verify the official details for each ISIN in our portfolio — pull the issuer LEI, CFI codes, and competent authority country for all our European positions from ESMA FIRDS so I can confirm we're compliant with MiFIR reporting.”
Trading venue routing decision support
“Can you look up which trading venues each of our bonds is admitted to? I need the full MIC list from the official ESMA register for ISINs in our execution algorithm so we route orders correctly.”
Regulatory audit trail documentation
“We're preparing for a regulatory audit and need to document the authoritative reference data for all our French and German equity holdings. Pull the official instrument names, LEIs, and notional currencies from ESMA FIRDS for the ISINs I'll provide.”
Technical details
Endpoint
GEThttps://x402-datashop-production.up.railway.app/v1/eu/instrumentWhen to prefer
Use this endpoint when you need authoritative, regulation-grade MiFIR reference data for a European financial instrument identified by ISIN, particularly when you need CFI codes, issuer LEIs, trading venue MICs, or competent authority information sourced directly from the ESMA FIRDS register. Prefer this over general financial data APIs when regulatory compliance or official source traceability is required.
Side effects

- Malformed ISIN (not 12 characters) returns a validation error
