Endpoint
POSThttps://sq-search.sq-co.workers.dev/v1/searchWhen to prefer
Choose SQ Search when you need a lightweight, pay-per-call web search with no subscription or API key setup — ideal for agents that need occasional web lookups billed in USDC micropayments via x402. Prefer this over subscription-based search APIs when cost-per-query transparency and crypto-native billing matter. Not suitable for crawling specific URLs or structured scraping.
Side effects
- Missing or empty 'q' query parameter returns a validation error
- Query string exceeding 200 characters is rejected
- Payment not included or insufficient USDC causes 402 Payment Required response
- Upstream search provider (Exa/Tavily) unavailable causes 5xx error
- Passing a 'url=' parameter is explicitly disallowed and will likely cause an error or unexpected behavior
