Endpoint
POSThttps://tollbooth.memerhuwhite.workers.dev/paid/markets/cross-platform-scanWhen to prefer
Use this endpoint when you need to search for prediction markets on a specific topic across multiple platforms simultaneously and want to identify arbitrage or comparison opportunities. Prefer this over single-platform lookups when cross-platform visibility matters.
Side effects
- No markets found for query — opportunities and candidate_matches arrays return empty
- External prediction market API downtime — partial or no results returned
- Malformed or overly broad query — returns empty result set
- Payment failure via x402 — call not executed
