AgentCite returns real, DOI-backed citations from 250M+ peer-reviewed works — for any topic, in one call. A REST API and an MCP server your agents can use. It never makes a source up.
Try it free → PricingLLMs invent citations. They produce plausible-looking references with fake DOIs that don't resolve — which ruins research, and gets content demoted by Google's E-E-A-T systems for unverifiable claims. Checking each one by hand doesn't scale.
One call returns the most relevant real studies on a topic — title, authors, year, journal, and a resolvable DOI — sourced live from openAlex (public-domain, CC0). Every result is a real record. There is no fabrication path.
Type a topic. Free tier is 25 requests/day.
Any MCP-compatible agent (Claude, Cursor, Codex…) can call the get_citations tool:
// MCP tool
get_citations({ topic: "collagen supplement skin elasticity", n: 5 })
// → real openAlex works with resolvable DOIs, relevance-ranked
Or hit the REST API directly:
GET https://agentcite-api.vercel.app/api/cite?topic=collagen+skin&n=5
