工具概览
OpenSERP 是一个开源的 SERP API 和托管云平台，用于搜索数据工作流。它处理浏览器自动化、多引擎解析和重试逻辑，返回包含标题、URL、摘要、排名和 SERP 特性的结构化 JSON。SDK、MCP 服务器和 n8n 集成使用的是同一份结构化响应。
该产品支持 Google、Bing、Yandex、Baidu、DuckDuckGo 和 Ecosia 的网页和图片搜索。OpenSERP Cloud 还提供多引擎的 megasearch 端点，一次调用即可查询多个引擎。它可以通过一个 API 调用六个搜索引擎、提取页面内容、跟踪竞争对手并提供 AI 洞察。
OpenSERP 既可以作为自托管、采用 MIT 许可证的引擎使用，也可以作为托管云服务使用。开源版本可免费自托管，无需 API 密钥、按查询收费，也没有超出用户自己机器能力的速率限制。OpenSERP Cloud 起步赠送 60 个免费额度，之后按成功的搜索收费，无需订阅。

常见问题
Is OpenSERP really free?
The open-source version is permanently free under the MIT license; self-hosting has no API key, per-query fee, or rate limit beyond your own machine. OpenSERP Cloud starts with 60 free credits and then charges per successful search with no subscription.
Is OpenSERP a free alternative to SerpApi, Serper, or Scale SERP?
The self-hosted version is a free alternative providing structured results for Google, Bing, Yandex, Baidu, DuckDuckGo, and Ecosia from one REST endpoint, with no subscription or vendor lock-in. OpenSERP Cloud is the hosted alternative priced per successful search.
Which search engines does the SERP API support?
Google, Bing, Yandex, Baidu, DuckDuckGo, and Ecosia for web and image search. Cloud also exposes multi-engine megasearch endpoints that query several engines in one call.
How do I self-host OpenSERP?
Use the Docker image or Go binary to start a local REST server. Full installation commands and configuration details live in the docs.
Do I need an API key to use OpenSERP?
No key is needed for the open-source self-hosted version. OpenSERP Cloud uses bearer-token API keys (osk_live_…) to meter usage and bill credits per successful response.
What output format does OpenSERP return?
JSON by default, with Markdown, TXT, and NDJSON output options when requested. The JSON shape stays consistent across engines with titles, URLs, snippets, rank, and SERP features.
What is a credit?
A credit is the billing unit across OpenSERP Cloud. For single-engine web search, billing is 1 credit per 10 returned result positions, rounded up.
Do failed requests cost credits?
No. Errors, timeouts, and empty result pages are never charged. Only successful responses with real data are billed.
Is there a subscription or minimum?
Neither. Credits are pay-as-you-go with no recurring fee and no minimum spend.
Do credits expire?
No. Purchased credits never expire. Top up once and draw down at your own pace with no monthly reset and no surprise renewals.
