Its Polymarket service closed on September 30, 2026, so this profile is a migration reference for existing users.

An application that relied on Struct may need several replacements rather than a single endpoint swap. The former service brought market discovery, order-book updates and wallet analytics together; each dataset and any derived calculations need to be mapped to a current source. The hosted Explorer has ended, while its separate open-source repository has its own installation requirements and lifecycle. Keep locally retained records: the shutdown notice does not offer a complete historical Polymarket export. ### Who it is for - Developers removing Struct dependencies from an existing application. - Researchers looking for the former Explorer code or preserving saved data. ## Features and coverage - **Former REST service** Market and analytics queries were available through one API integration; this describes the retired offering. - **Former streaming delivery** Push updates supported applications that needed ongoing market data rather than repeated polling. - **Explorer source code** A separate open-source project contains market, trader and builder analytics views. - **Shutdown guidance** The notice explains closure, migration constraints and subscription closeout. ## Workflows with Struct ### Replace a dashboard's data sources Inventory Struct endpoints and calculated metrics. Map event discovery to Gamma, live books to CLOB and account activity to the Data API. Reconcile sample records and P&L calculations before switching. ### Protect existing research history Build the historical dataset from dated observations: retain the Struct responses you saved locally with their timestamps, and source missing order-book periods from an archive provider. A current quote is a new observation and cannot supply the earlier book's orders or depth. ## Pricing and total cost Struct's closed Polymarket service has no subscription available to buy. For existing customers, the shutdown notice sets out billing closeout: renewals were halted ahead of closure, refunds were scheduled in proportion to unused prepaid time, and enterprise closeout follows a separate process. ## Getting started **Before you start:** Struct's Polymarket API and hosted Explorer have been discontinued. 1. List the Struct calls and derived metrics your application still uses. 2. Select replacement sources for each dataset and delivery method. 3. Change authentication and field mappings, then compare sample market and wallet records. 4. Remove the retired endpoints once the replacement works. A complete historical Polymarket export is unavailable from Struct.

A closer look ## Ratings & reviews Editorial rating **1.0**/ 5 0 user reviews PredictionToolkit editorial ### Our take on Struct Struct no longer serves as a choice for a new Polymarket integration. Its remaining value is understanding the migration; data feeds and derived metrics must be replaced elsewhere. Based on documented features, setup and access terms.

No. Choose a current official API or another data provider. ### Is the Explorer source code still a separate project? Yes. See its dedicated profile for the repository and installation requirements; it is distinct from the closed hosted service. ### What happened to subscriptions? Renewals stopped before shutdown. The notice schedules prorated refunds for unused prepaid time and treats enterprise closeout separately. In this profile
