OpenFIGI API

Varies by plan (check documentation)

Overview

OpenFIGI is a free API from Bloomberg that lets you look up financial instrument identifiers (FIGIs) for equities, indices, futures, and options. You can map tickers, ISINs, CUSIPs, and other identifiers to standardized FIGI codes used across global markets. It is a valuable tool for developers building financial data pipelines who need to normalize instrument identifiers.

💡

Beginner Tip

You can make up to 250 requests per minute without an API key, which is plenty for getting started; register for a free API key to increase your limits when needed.

Common Errors & Troubleshooting

400 Bad Request The mapping request body is malformed or missing required fields
Ensure your request body is an array of mapping objects each containing at least idType and idValue fields.
Empty data array in response No FIGI matches found for the provided identifier
Double-check the identifier value and type; try alternative ID types to find a match.
429 Too Many Requests Exceeded the unauthenticated rate limit of 250 requests per minute
Add your API key in the X-OPENFIGI-APIKEY header to increase limits, and implement request throttling in your code.
