Find web pages similar to a given URL via Exa's AI-powered search, settled over MPP/Tempo.
What it does
This endpoint wraps Exa's "Find Similar" functionality behind the Micro-Payment Protocol (MPP) on Tempo. Exa is an AI-powered web search engine that provides semantic search, content retrieval, and similarity lookups. The /findSimilar endpoint is intended to accept a URL and return a list of web pages that are semantically similar to the provided page.
The endpoint is hosted at exa.mpp.tempo.xyz and is expected to settle payments via the Tempo L2 network using pathUSD. However, during probing the endpoint returned 404 on both HEAD and GET requests, and no 402 MPP payment challenge was captured. The root domain and all documentation paths also returned 404. This suggests the endpoint may not currently be live or may have been moved/decommissioned.
Because no schema, pricing information, documentation, or working challenge was captured, all details about request/response format and cost are inferred from the endpoint name and the existing Bazaar listing description. Users should verify availability before attempting integration.
