What it does

Brave Search AI Answers is an endpoint that accepts chat-style messages and returns AI-generated answers grounded in Brave's independent web search index. It is part of a broader suite of Brave Search endpoints (web, news, image, video, LLM context) exposed through the Locus MPP (Micropayment Protocol) gateway. This specific endpoint (`/brave/answers`) supports an OpenAI-compatible messages array, optional streaming, and two model tiers: "brave" and "brave-pro" (default).

Each call costs 85,000 base units of pathUSD (a 6-decimal stablecoin on Tempo L2), which works out to $0.085 per request. The endpoint uses the MPP "charge" intent, meaning each request is a one-shot payment. The request body requires a `messages` array of `{role, content}` objects; optional parameters include `model`, `stream`, and `max_completion_tokens`. The endpoint is POST-only; HEAD and GET probes return 404, which is expected for a POST-based API.

The broader Brave Search suite available at the same gateway includes web search, news search, image search, video search, and LLM context endpoints, each priced at $0.035 per query. All endpoints settle payments via the Tempo method on pathUSD. Documentation is referenced at the official Brave Search API docs and the Locus MPP skill file.

The OpenAPI spec is well-structured with clear request schemas, pricing, and multiple endpoints documented. However, no response schema is provided, the probe returned 404 on HEAD/GET (expected for POST-only but no 402 challenge was captured), crawl pages yielded no additional documentation, and no example responses are available.

Warnings

  • —No 402 MPP challenge was captured on HEAD/GET probes; the endpoint is POST-only so liveness could not be confirmed via the probe methods used.
  • —No response schema is documented in the OpenAPI spec — response structure must be inferred.
  • —The currency address 0x20c000000000000000000000b9537d11c60e8b50 is assumed to be pathUSD with 6 decimals based on the Tempo settlement method; if this assumption is wrong, the price calculation would be incorrect.
  • —All crawled pages returned 404 JSON errors; no supplementary documentation was retrieved from the gateway itself.
