The data

Polymarket data,
ready to work with.

A market search can return several contracts for one event. In a recorded search for the 2026 F1 Drivers’ Champion, ten results included individual driver questions under the same event URL. The selected Kimi Antonelli contract has its own question, active state, scheduled end date and a Yes-side quote from the collection time. That quote is a market price, not a guaranteed probability or a forecast from Monocrawl. The returned list was not ordered by likelihood: its first result was a different driver. Use the contract ID and source URL when comparing later snapshots so a similar question is not mistaken for the same market.

Before you build

Polymarket API questions,
answered.

Need to check a particular workflow?
Talk to us

Is the first search result the most likely outcome?

No. The recorded F1 search returned a different driver first. Inspect each question and exact contract ID; result order is not a probability ranking.

Are outcome prices predictions or live guarantees?

No. They are dated market quotes that can move or disappear. Preserve the capture time and source URL; do not treat a saved quote as trading advice.

What Polymarket operations can I use?

The catalogue shows 1 currently available operations with their individual prices. Open an endpoint for its accepted inputs, returned fields and limitations.

How much does the Polymarket API cost?

Start with 150 free credits. Paid subscriptions start at $29 per month for 10,000 credits, before applicable tax. Each operation has its own price. Check the endpoint reference for variable charges. Compare plans

How do I authenticate requests?

Use your Monocrawl API key in the x-api-key header. The endpoint reference lists any additional inputs needed for the operation. Authentication guide

What request limits apply?

Limits depend on your Monocrawl plan. The Free account ceiling is 600 requests per minute and 50 simultaneous requests. Endpoint capacity and Free daily protections also apply; these ceilings do not guarantee source throughput. Read the limits guide

What should I know about Polymarket coverage?

Outcome prices change and are market quotes, not guaranteed event probabilities or investment advice. Search order is not a ranking by likelihood; inspect the question, event and contract ID before comparing results.
