Endpoint
GEThttps://agentdiet.dev/v1/prediction-markets?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live crowd-sourced probability estimates for discrete future events — especially macro, crypto, or AI/political outcomes — rather than relying on analyst forecasts or news sentiment. Prefer it over general news APIs when you need quantified market-implied probabilities and volume-backed sentiment from active traders on Polymarket.
Side effects
- Topic keyword too vague — no matching Polymarket market found, returns empty or null result
- Polymarket API upstream outage — endpoint returns error or stale data
- Payment failure (HTTP 402) if x402 USDC micropayment is not properly attached
- Rate limiting if too many calls are made in quick succession
- Topic returns multiple ambiguous markets with no clear best match
