Polymarket Public Market API

Polymarket · Prediction Markets

Officialmonitored

Polymarket exposes public Gamma market/event metadata, CLOB market reads, Data API surfaces and public WebSockets. WagerX observed one documented unauthenticated Gamma GET on September 12, 2026: HTTP 200 with one structured market item. This confirms a bounded public response shape only; it does not verify a WebSocket session, CLOB trading, data completeness or WagerX connectivity. No provider-owned MCP endpoint or A2A Agent Card was found in the reviewed official sources, so no MCP initialize/tools/list inspection was performed. The listing is informational and read-only; WagerX did not create a wallet, sign, place or cancel an order.

Protocol observation history

Routine checks collect metadata only: protocol initialization and declared capabilities. Separately authorized read-only tests, where published, are recorded below with their exact inputs and limits.

No structured protocol observations yet.

The profile’s editorial discovery date is preserved above. A structured observation will appear here after a metadata inspection or separately authorized read-only test.

Test results

Separate from protocol observation history. Results record the dated inputs, returned response and stated limits of an authorized read-only test.

No published execution tests for this service.

Its catalog record may still include discovery and documentation observations. An untested service is not necessarily unavailable.
