Technical details
Endpoint
POSThttps://agent402.tools/api/polymarket-marketWhen to prefer
Use this endpoint when you need comprehensive details about a specific Polymarket market and already know the market slug or numeric ID. Prefer this over generic web scraping when you need structured data including CLOB token IDs for further orderbook or trade history lookups.
Side effects
- Neither slug nor id provided — returns validation error
- Invalid or non-existent slug/id — returns not found error
- Polymarket API upstream outage — returns 502 or timeout
- Market exists but has been delisted — may return empty or error response
