# Research Paper APIs and Tools: arXiv, Semantic Scholar and More

Open APIs and tools for finding, mapping and reading scientific papers, for a research agent or your own literature review.

## Open sources

- Semantic Scholar: A free search engine for scientific papers from Ai2, with a public Academic Graph API and bulk dataset releases of papers, authors, citations and abstracts. [API, no key; commercial use with conditions] https://agentgid.com/resources/semantic-scholar/agent.md
- Connected Papers: A web tool that takes one paper and draws a graph of related papers grouped by similarity, so you can see earlier and later work in a field. [API with key; commercial use with conditions] https://agentgid.com/resources/connected-papers/agent.md
- Elicit: An AI research assistant that searches 138 million academic papers and 545,000 clinical trials and turns the results into tables, systematic reviews and cited reports. [API with key; commercial use with conditions] https://agentgid.com/resources/elicit/agent.md
- Consensus: An AI search engine over 400 million scholarly papers that answers research questions with cited summaries and a meter of how many studies say yes or no. [API with key; commercial use unclear] https://agentgid.com/resources/consensus/agent.md
- SciSpace: An AI research assistant for reading and writing papers: chat with a PDF, search over 280 million papers, pull data out of many PDFs and format citations. [no API; commercial use unclear] https://agentgid.com/resources/scispace/agent.md
- arXiv: The open preprint server for physics, maths, computer science and other fields, with a free keyless query API, OAI-PMH metadata harvesting and full-text PDFs and sources in bulk on Amazon S3. [API, no key; commercial use ok] https://agentgid.com/resources/arxiv/agent.md
