AI-powered answers via Exa search, settled over MPP on Tempo L2.
What it does
This endpoint is listed as an MPP (Micropayment Protocol) gateway to Exa's AI-powered answer service, hosted at exa.mpp.tempo.xyz/answer. Exa is known as an AI-powered web search and content retrieval platform; this particular route is intended to return AI-generated answers to queries, with payment settled via the Tempo L2 network.
However, during probing the endpoint returned HTTP 404 on both HEAD and GET requests, and no valid MPP 402 challenge was captured. All crawled pages on the origin domain (root, /docs, /api, /pricing, /README) also returned "Not Found." This means the endpoint is currently not responding as expected — it may have been moved, deprecated, or is only accessible via a different HTTP method (e.g., POST) that was not probed. No OpenAPI schema, pricing details, or documentation were recoverable.
Because no live challenge or documentation could be obtained, nearly all details about capabilities, pricing, and request/response format are inferred from the existing catalog title and description. Users should verify availability before attempting integration.
