The endpoints in this API reference are split along 2 axes: the type of data being fetched and the universe being fetched.

  • The bond endpoints cover data on government and corporate bonds, whereas the muni endpoints cover the US municipal bond market. The munis are split from the rest of the bonds as they have unique characteristics and data schemas.

  • The search endpoints are meant for searching according to user-defined filters, such as maturity ranges, currency, country, etc. This endpoint will return a limited set of fields for each bond. This endpoint does not count toward your ISIN quota, so you can make as many searches as you want.

  • The reference endpoints are meant for fetching the full reference data on a particular set of ISINs.

  • The pricing_latest and pricing_history endpoints are meant for fetching the latest or historical pricing data on a set of ISINs, respectively.

Note: to receive the data in csv format, use the header 'Accept: text/csv' in your request. Using text/csv will bypass the default query limit of 1000 returns per request (with pagination), so we recommend that it is only used when you actually intend to download data in bulk into a csv file.
