# Alternatives to Struct

By PredictionToolkit · Updated 2026-10-01

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

Data API**4.0**Editorial

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

Data API**4.0**Editorial

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.
