Pay-per-use web search returning structured results via Browserbase headless browsers.
What it does
Browserbase's /search endpoint provides web search with structured results, priced at $0.01 per request. It is part of the Browserbase Payment Gateway, which offers pay-per-use headless browser sessions, web search, and page fetching for AI agents. The service requires no API keys or accounts — callers pay per request using crypto (USDC on Base via x402, or Tempo chain via MPP).
The /search endpoint accepts POST requests and returns structured search results. It sits alongside companion endpoints for browser session management ($0.12/hour) and page fetching ($0.01/request). The gateway advertises support for both the x402 protocol (HTTP 402 + X-PAYMENT header with USDC on Base) and the MPP protocol on Tempo mainnet.
Note: During probing, the /search endpoint returned 404 on both HEAD and GET methods rather than the expected 402 MPP challenge. Since the endpoint is documented as accepting POST requests, the probe may have used the wrong HTTP method. The endpoint's actual liveness via POST could not be confirmed from the probe data alone.

}Endpoint
Quality
The endpoint is documented on the provider's landing page with pricing ($0.01/request) and method (POST /search), but the probe did not capture a 402 MPP challenge (returned 404 on HEAD/GET — likely because the endpoint only accepts POST). No OpenAPI schema, no response examples, and no dedicated docs pages were available. The request/response schemas are inferred.
Warnings
- —Probe returned 404 on HEAD and GET; the endpoint is documented as POST-only, so liveness via POST could not be confirmed
- —No OpenAPI or schema documentation available — request and response formats are inferred
- —Docs, API, pricing, and README pages all returned 'Cannot GET' errors
- —Example response JSON is unavailable; structured result format is unknown
