FAQ

About the Polymarket Markets API

The AnyAPI Polymarket Markets API returns Polymarket markets data as normalized JSON from one POST call to /v1/run/polymarket.markets. Discover Polymarket prediction markets (question, outcome prices, volume, liquidity, and end dates) by keyword or sorted by activity, as normalized JSON. AnyAPI returns one normalized schema whichever source serves it. It costs $5.28 per 1,000 results, and never more than $0.132 for a single request, in US dollars with no subscription and no monthly minimum. Over the last 30 days, 100.0% of Polymarket markets calls through AnyAPI succeeded, with a median response time of 5.8 seconds across 5 measured calls.

It costs $5.28 per 1,000 results, and never more than $0.132 for a single request, in US dollars with no subscription and no monthly minimum. You fund one USD wallet and each call draws it down. Some failed wallet-funded requests incur processing charges that we pass through at cost, with no markup; the error response shows the amount charged.

Discover Polymarket prediction markets (question, outcome prices, volume, liquidity, and end dates) by keyword or sorted by activity, as normalized JSON. The response is normalized JSON with the same envelope every AnyAPI endpoint returns, so parsing a second endpoint is a change of URL and nothing else.

Over the last 30 days, 100.0% of Polymarket markets calls through AnyAPI succeeded, with a median response time of 5.8 seconds across 5 measured calls. These are AnyAPI's own measurements of traffic through the gateway, recomputed continuously, not a published service-level target.

Yes. A new AnyAPI account starts with $0.10 of free balance and no card required.

Send a POST request to https://api.getanyapi.com/v1/run/polymarket.markets with your AnyAPI key in an "Authorization: Bearer" header and the input as a JSON body. The same key and the same wallet work on every AnyAPI endpoint.

No. You add US dollars to one prepaid AnyAPI balance and each request draws it down. There is no monthly plan and no minimum, and the same balance pays for every AnyAPI endpoint.

Yes. Install @getanyapi/sdk from npm for TypeScript or getanyapi from pip for Python. Both call every AnyAPI endpoint with the same key, and any HTTP client works too.

Yes. An agent can connect to the AnyAPI MCP server at https://api.getanyapi.com/mcp, or create its own free-trial key with one unauthenticated POST to https://api.getanyapi.com/agent/signup and call this endpoint over HTTP.
