← Struct: Retired Polymarket API and Migration

Alternatives to Struct

By PredictionToolkit · Updated

Choose a replacement around the data your application consumes. The two official interfaces below solve different tasks; this selection is neither a ranking nor a claim of complete Struct-equivalent coverage.

Match the data task

Official Polymarket CLOB price and book documentation
Polymarket CLOB API
Data API4.0Editorial

CLOB API: read bids, asks and trading constraints for an outcome token. Public books do not establish private-trading access or Struct-equivalent history.

  • Access API
Official Polymarket public analytics integration guide
Polymarket Data API
Data API4.0Editorial

Data API: inspect current account data and the documented v1-to-v2 migration. Verify current fields and pagination; old responses are not interchangeable.

  • Access API

Keep identifiers distinct

Separate an event, a market and the particular outcome token used for a book. A market can have several outcome token IDs; preserve the label-to-token mapping.

Test a small migration

  • Record an expected response for a chosen task.
  • Check identifiers and pagination.
  • Compare missing or changed fields.
  • Run the checks in your own client before relying on the replacement.

This selection requires a reviewed primary source, useful profile and clear task match. It makes no uptime, completeness or fee ranking. Gamma discovery and other streaming surfaces need their own integration review.
