Polaris provides REST endpoints at https://api.polaris.supply. Most endpoints are public. Add bearer auth only when you need broader historical access, account-tier visibility, or a dataset policy that requires it. Choose the endpoint that matches your task, then read the smaller page for that endpoint.

Start with the right endpoint

​
Endpoint families

​
Metadata

  • GET /catalog for public market discovery, with optional account-tier visibility when you send bearer auth

​
Historical files

  • GET /snapshots for public hourly snapshot listing. Add raw=true to list venue-native raw snapshot files (requires paid auth)
  • GET /download for bulk daily download manifests or single-file download. Use source/market/date for the bulk JSON manifest, or key for one file

​
Common response patterns

/snapshots returns a paginated JSON response:
/download supports two response shapes: a bulk daily manifest when you request source, market, date, and mode=json, or a single-file redirect / JSON URL response when you request key.
