Endpoint
POSThttps://x402-services-production.up.railway.app/api/predict/oddsWhen to prefer
Use this endpoint when you need crowd-sourced implied probabilities for any real-world event (political, economic, sports, crypto) across many markets simultaneously via keyword search. Prefer this over the slug-based sibling endpoint when you don't know the exact market slug and need to discover relevant markets by topic.
Side effects
- No markets found for the search query — returns empty list
- Query too vague returns unrelated markets
- Polymarket API unavailable — upstream fetch failure
- Invalid limit parameter type causes schema validation error
- Payment not received — 402 response blocking access
