Technical details

Endpoint

GEThttps://blockrun.ai/api/v1/pm/markets/search?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to discover prediction markets on a specific topic without knowing which platform hosts them. It is especially valuable when comprehensive coverage across Polymarket, Kalshi, Limitless, Opinion, and Predict.Fun is needed in a single call, saving the need to query each venue individually.

Side effects

No markets found matching the search query — returns empty result set
Query too vague — may return unrelated or low-relevance markets
Rate limiting or payment failure — 402 payment required error if x402 payment not attached
Upstream venue unavailable — partial results if one or more platforms are temporarily down
Invalid query format — returns 400 bad request
