OpenAPI

Tools that import APIs from an OpenAPI description can use https://quarry.market/openapi.json. It covers the dataset contract, the x402 pay-per-question endpoint and the subscription routes (bearer: an API key). MCP remains the better option when available: it adds free search across every dataset.
