OpenSERP

OpenSERP is an open-source, self-hostable SERP API that returns structured search results from Google, Bing, Yandex, Baidu, DuckDuckGo and Ecosia through one REST interface, alongside OpenSERP Cloud, a managed pay-as-you-go version of the same API adding page extraction, multi-engine megasearch, image search and scheduled rank monitoring. The self-hosted server ships an MIT-licensed Go binary and CLI with a published OpenAPI 3.0.3 contract, a v2 response envelope carrying query echo, metadata, normalized results and pagination, plus cache, proxy-pool and circuit-breaker telemetry endpoints. OpenSERP Cloud adds bearer-token authentication, credit-metered billing, engine health routing, batch URL extraction and Search Monitor webhooks, and the project publishes first-party JavaScript and Python SDKs, an MCP server and an n8n community node.

OpenSERP publishes 1 API on the APIs.io network: Server (self-hosted). Tagged areas include Company, Search, SERP, Search API, and Web Scraping.

The OpenSERP catalog on APIs.io includes 1 event-driven AsyncAPI specification.

OpenSERP’s developer surface includes documentation, API reference, getting-started guide, authentication, pricing, engineering blog, signup flow, and 37 more developer resources.
