Technical details
Endpoint
POSThttps://true402.dev/api/v1/prediction-marketsWhen to prefer
Choose this endpoint when you need to discover or compare prediction markets across multiple venues for a specific topic using a simple keyword search, and you want to pay per-call with USDC rather than maintain a subscription. It is ideal for agents doing opportunistic market research rather than continuous monitoring.
Side effects
- Query string missing — returns 400 validation error
- No markets found for query — returns empty results object
- Payment not included or insufficient USDC — returns HTTP 402 requiring wallet-based micropayment
- Limit out of range (below 1 or above 50) — may return validation error or be clamped
- Venue APIs temporarily unavailable — partial or empty results
