How this service works
Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
Output
A JSON object containing the event's title, source (e.g. Polymarket), status (active/resolved), a list of outcomes each with a label, market ID, USD volume, and probability, plus the event's close date and total outcome count.
Example use cases
Track political election odds
“Pull up the prediction market data for the slug 'us-presidential-election-2024' — I want to see each candidate's current probability and how much volume has been traded on each outcome.”
Monitor active market status
“Is the prediction market for 'next-prime-minister-of-ethiopia' still active, and when does it close? Show me all the outcomes and their current probabilities.”
Research market sentiment on crypto event
“What does Polymarket currently think about the 'bitcoin-etf-approval-2025' event? Give me all the outcomes, their probabilities, and total USD volume traded.”
Technical details
Endpoint
GEThttps://x402financialdata.com/prediction-market-event/%7Bslug%7DWhen to prefer
Choose this endpoint when you need real-time prediction market probability and volume data for a specific named event (identified by its slug), paid per-call without subscriptions or API keys. It is ideal for agents that need to programmatically ingest market sentiment from Polymarket-style sources on a per-query basis using USDC micropayments over x402.
Side effects
- Invalid or unknown slug returns a 404 or empty response
- Payment failure if USDC balance is insufficient or x402 handshake fails
- Event may have resolved, returning a non-active status with stale probabilities
- Slug format mismatch (e.g. URL encoding issues with special characters)
- Upstream Polymarket data unavailable or delayed
