Polymarket APIs and Data Providers

Choose Polymarket data access by coverage: markets, order books, wallet activity or historical records.

How to choose data apis

Which data do you need, and how will you receive it?

  • Match the provider to the entity you need: a market, outcome token, trade or wallet.
  • Check REST versus streaming delivery, authentication, coverage and rate limits.
  • Distinguish public data reads from signed account actions; an SDK is a separate choice.
