How this service works
All active crypto markets with live probabilities in one call — One-call board of the most active crypto prediction markets: top markets by volume with blended live probabilities, resolution dates, and per-market slugs for drill-down. The bulk read for agents tracking the state of crypto at a glance.
Output
A JSON object containing a 'data' field with the category label ('crypto') and an array of up to 50 market objects, each including: slug (unique market identifier for drill-down), question (market description), probability (0–1 float representing current blended odds), volume_24h_usd (24-hour trading volume in USD), and resolution_date (ISO date string). A 'meta' object is also returned with request metadata.
Example use cases
Crypto market sentiment dashboard
“Give me a live snapshot of the most active crypto prediction markets — show me the top 20 by volume with their current probabilities and when they resolve.”
Automated crypto event tracker
“Every hour, check the top 50 active crypto prediction markets and alert me if any probability moves more than 5 points since the last check.”
Research briefing on crypto odds
“I'm writing a briefing on what the prediction markets think will happen in crypto this month — pull the full board of active markets with their live probabilities and resolution dates.”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/board/cryptoWhen to prefer
Choose this endpoint when you need a broad, ranked overview of the entire active crypto prediction market landscape in a single call — especially for dashboard builds, monitoring agents, or research briefings. It is preferable over per-market drill-down endpoints when you don't yet know which specific markets are active or relevant. Use sibling 'moves' endpoints instead if you specifically want to track probability changes over time rather than current state.
Side effects
- Payment failure (402): x402 micropayment of $0.03 USDC not fulfilled — request blocked
- Invalid limit parameter: value outside 1–50 range returns a validation error
- Service unavailability: upstream prediction market data source offline, returns 5xx
- Empty markets array: no active crypto markets found (rare edge case)
- Rate limiting: too many rapid calls may result in throttling
