SERP context is different from answer APIs
OpenSERP keeps URLs, ranks, engines, and snippets visible so AI systems can preserve provenance and reviewability.
Comparison
Search API comparison for LLM grounding
AI grounding workflows need source discovery, extractable pages, and traceable URLs. OpenSERP is a SERP-first option for teams that want ranking signals and source URLs alongside extraction.
The short answer
Reach for OpenSERP when you want real search engine results - ranks, URLs, snippets - that your agent can cite and a reviewer can trace, plus the option to self-host. If you want semantic/neural retrieval over a curated index, Exa is built for that; if your workload is mostly heavy crawling, Firecrawl leans that way. They're good tools for different shapes of the same problem.
Can the workflow discover fresh URLs from search engines?
Does it expose ranking and source context?
Can pages be extracted into LLM-ready text or markdown?
Is there a free self-hosted path for teams that need control?
| Provider | Model | Focus | Best fit |
|---|---|---|---|
| OpenSERP Cloud | Self-hosted OSS plus managed Cloud API | SERP results, ranks, URLs, snippets, extraction | AI workflows that need search engine context and self-hosting |
| Tavily | Managed API | Search and extract workflows for AI agents | Managed agent search pipelines |
| Exa | Managed API | Neural/web search for AI applications | Semantic search-oriented AI discovery |
| Firecrawl | Managed and developer tooling | Crawling, scraping, and page extraction | Extraction-heavy workflows |
How to decide
Pair search with extraction
A practical grounding pipeline can search first, choose sources, then extract selected pages into markdown or text.
Frequently asked questions
What is LLM grounding?
Grounding means fetching live web results at query time and passing them to the model as context, so answers cite current sources instead of relying on stale training data.
Why do ranks and source URLs matter for grounding?
They preserve provenance: your agent can choose which sources to trust, cite the exact pages used, and a reviewer can trace every claim back to a URL and its search rank.
Is there a self-hosted option for agent search?
Yes. OpenSERP's open-source engine runs locally with Docker, so agents can search without sending queries to a third-party API. The managed Cloud API uses the same response shape.
