Research Index
Search papers, read paper passages, find related work, and search across related GitHub repos
Firecrawl Research is a purpose-built index for scientific and engineering research agents. It exposes a research-specific toolset for searching papers, inspecting paper metadata, reading relevant full-text passages, discovering related papers through structural expansion, and searching over research-related GitHub repos.
- Find papers by topic, method, benchmark, author, or category
- Inspect canonical paper metadata and source ids
- Read the passages in one paper that answer a specific question
- Expand from strong seed papers to related papers, citers, or references
- Search GitHub history and READMEs for implementation notes, bugs, and design discussions
To give your agent access to the Research Index, we strongly recommend using our CLI or MCP, combined with our dedicated research skill, which you can install with:
npx skills add firecrawl/skills@firecrawl-research-indexEndpoints
| Task | Endpoint |
|---|---|
| Search papers | GET /search/research/papers |
| Inspect metadata or read passages | GET /search/research/papers/{id} |
| Find related papers | GET /search/research/papers/{id}/similar |
| Search GitHub history | GET /search/research/github |
Search papers
Search paper abstracts with a natural-language query. The response returns ranked papers with canonical paperId, preferred primaryId, source ids, title, abstract, score, and optional ranking signals.

Inspect a paper
Use a canonical paperId or a source-specific primaryId.

curl -s "https://api.firecrawl.dev/v2/search/research/papers/arxiv:1706.03762"Read paper passages
Add query to the same paper path to retrieve the top full-text passages for a question. This is useful for verifying whether a candidate paper actually contains a method, dataset, constraint, or result before you include it.

Expand from one or more seed papers through semantic expansion and rank the candidates against a natural-language intent.

Search GitHub history
Search GitHub issues, pull requests, discussions, and repository READMEs for implementation details and engineering prior art.
