How this service works

Output

Returns a JSON object containing the market ID queried, source attribution, a trades array (each with side, size, price, outcome label, timestamp, USDC value, taker wallet address, and transaction hash), total trade count, query timestamp, and a disclaimer that data is informational only.

Example use cases

Technical details

Endpoint

GEThttps://api.sitecheck-api.workers.dev/api/pm/trades?utm_source=zero.xyz

When to prefer

Use this endpoint when you need recent trade-level data (individual buy/sell events) for a specific Polymarket prediction market, as opposed to aggregate order book data or top-level market metadata. Prefer this over Polymarket's direct API when you need pay-per-call access without API key management, or when combining with other SiteCheck tools in a single workflow.

Side effects

Invalid or unknown market/asset ID returns empty trades array or error
Missing required 'market' query parameter returns 400 bad request
Limit exceeding 100 is capped or returns an error
Network timeout or Polymarket upstream API unavailability returns 5xx
Malformed market ID format may return no results
