Use when an agent needs a concise, cited answer to one research question with optional domain scope and freshness, from one bounded pay-per-call web search. Returns the answer synthesized only from the retrieved sources, source URLs and labels with retrieval timestamps, an explicit insufficient-evidence refusal when the sources do not support an answer, and a machine-readable receipt of the upstream cost and settlement.
How to buy
This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.
