Each call is charged $0.035 in pathUSD on Tempo L2 with no subscription or API key required — just a per-request payment challenge.\n\nThe news-search endpoint accepts a query string and optional parameters for result count (1–50, default 20), freshness filtering (past day, week, month, year, or custom date range), and country code. It is part of a broader Brave Search suite on the same gateway that also offers web search, image search, video search, LLM context retrieval, and AI answers.\n\nThe endpoint uses POST with a JSON body. The only required field is `q` (the search query). The MPP probe returned 404 on HEAD/GET, which is expected since the endpoint is POST-only. The OpenAPI spec confirms the payment intent is \"charge\" (one-shot per call) via the Tempo method. Documentation is referenced at https://api.search.brave.com/app/#/documentation and https://beta.paywithlocus.com/mpp/brave.md.","tags":["search","web-search","privacy","news","images"],"capabilities":["news-search","freshness-filter","country-filter","result-count-control","pay-per-call","tempo-l2-settlement","privacy-first-search"],"categories":["search"],"synonyms":["brave news api","news search api","brave search news","current events search","headline search","news aggregation api","brave mpp news"],"warnings":["Endpoint returned 404 on HEAD/GET probes; it is POST-only so liveness is inferred from OpenAPI spec but not directly confirmed via 402 challenge","No response schema documented — output format must be inferred from Brave Search API docs","Currency address 0x20c000000000000000000000b9537d11c60e8b50 assumed to be pathUSD with 6 decimals based on Tempo L2 conventions"],"endpointUrl":"https://brave.mpp.paywithlocus.com/brave/news-search","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"brave.mpp.paywithlocus.com","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.620","qualityRationale":"OpenAPI spec is well-defined with clear request schema and payment info, but no response schema or example response is provided.
