How this service works
A security by ISIN, CUSIP or ticker (with an optional exchange code): its OpenFIGI id, name, ticker, exchange, security type and market sector, and for an ISIN the issuer's LEI and legal name from GLEIF. ISIN and CUSIP check digits are verified before the call. Attribution: FIGI by OpenFIGI; LEI by GLEIF.
Output
Returns a JSON object containing the original query parameters, a list of matching securities (each with FIGI, name, ticker, exchange, market sector, and security type), the issuer's LEI and name sourced from GLEIF, the timestamp of the check, and data attribution and disclaimer notices.
Example use cases
Resolve ticker to FIGI for trading system
“I need the OpenFIGI identifier for AAPL on the US exchange — can you look it up so I can use it in my order routing system?”
Enrich compliance data with issuer LEI
“We have an ISIN of US4592001014 and need the issuer's LEI number for our KYC compliance records — can you pull that?”
Map CUSIP to exchange listings
“Can you take CUSIP 037833100 and tell me all the exchanges where this security is listed along with its FIGI codes?”
Technical details
Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/securities/id?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve financial security identifiers — ISIN, CUSIP, or ticker — to canonical FIGI codes, issuer LEI numbers, or multi-exchange listings. It is ideal for compliance workflows requiring LEI enrichment, order routing systems needing FIGI, or any pipeline that must map between different financial identifier standards. Prefer this over generic financial data APIs when you specifically need FIGI/GLEIF data sourced from OpenFIGI and GLEIF.
Side effects
- Invalid or malformed ISIN (not 12 characters) returns an error
- Unknown ISIN/CUSIP/ticker not found in OpenFIGI returns empty securities array
- Ambiguous ticker without exchange code may return multiple exchange listings
- OpenFIGI or GLEIF upstream service unavailability causes lookup failure
- Payment required (x402) if USDC payment is not provided
