How this service works

Pay-per-call structured web data. Failed or empty runs are not charged.

Output

A JSON object containing a count of matched records and an array of items, each with fields such as marketId, eventId, question, eventSlug, eventTitle, marketSlug, recordType, and description. The product field confirms the data source as Polymarket.

Example use cases

Monitor election market sentiment

“Get me the top 25 active Polymarket election markets sorted by 24-hour volume with at least $50,000 in liquidity — I want to see the questions, event titles, and descriptions so I can track current political sentiment.”

Research expiring crypto markets

“Find all active Polymarket crypto markets that are closing within the next 1440 minutes and have at least $10,000 in total lifetime volume, sorted by end date — return up to 100 results.”

Keyword search for sports event markets

“Search Polymarket for markets matching 'NBA Finals' and 'Super Bowl', return up to 50 results per search phrase, show me both active and closed records sorted by total lifetime volume.”

When to prefer

Choose this endpoint when you need structured, filterable Polymarket data without managing Polymarket's own API authentication or pagination — especially when querying by category, keyword, liquidity, or volume thresholds simultaneously. The pay-only-on-success model makes it safe for exploratory or conditional agent workflows where empty results are possible.

Side effects

Empty result set (count: 0) if filters are too restrictive — not charged
Payment failure if x402 USDC balance is insufficient
Timeout or upstream Polymarket API unavailability
Invalid enum values for sortBy, status, or itemType return validation errors
maxItemsPerSource too low combined with selective filters may miss relevant records
