Live arXiv preprint search for AI research agents.
Research agents hallucinate citations. Dynamic Feed serves real arXiv preprint records — title, authors, arXiv id — keyless over MCP or REST, each signed and sourced, so the agent cites a real, verifiable record instead of inventing one. (arXiv is a preprint server; most results aren't peer-reviewed.)
The call
Keyless over MCP, or one REST call with a free key. Every datapoint is provenance-stamped and citeable.
# Keyless over MCP — point any client at https://dynamicfeed.ai/mcp
# Or one signed REST call (free key) — full reference at https://dynamicfeed.ai/docs:

A model asked for a citation will often invent one. Dynamic Feed's research_papers tool returns real arXiv records — title, authors, arXiv id — in a provenance envelope, signed over their exact bytes; the source is arXiv (Cornell University), and each result carries its arXiv id and the exact time the record was served. arXiv is a PREPRINT server — most results are not peer-reviewed, and a record existing is not a judgement of the paper's validity. The agent cites a sourced record it can verify against /.well-known/keys (authenticity and integrity — not a guarantee the paper is genuine, current, or correct). It surfaces what arXiv returned at a time — not every paper on a topic — and it does not rank or endorse the research. (For broader scholarly metadata, the separate scholarly_search tool draws on OpenAlex.)
Use it for
- Stop a research agent inventing citations — ground it in real, sourced arXiv records
- RAG over preprint literature with citeable, signed records
- A verifiable record of what an arXiv search returned, at a time
- Lit-review agents that must cite a real, sourced record
FAQ
Does this stop citation hallucination?
It gives the agent real, sourced arXiv records to cite instead of inventing them. The agent still has to use them — but a citeable, signed record beats a guess.
Is this peer-reviewed research?
No — the source is arXiv, a preprint server, so most results are not peer-reviewed, and a record existing is not a judgement of validity. For broader scholarly metadata, our separate scholarly_search tool draws on OpenAlex.
What does the signature prove?
That Dynamic Feed returned this exact record at this time and it hasn't been altered since — authenticity and integrity, verifiable against /.well-known/keys. Not that the paper is genuine, current, or correct.
