Programmatic access to the 39+ million biomedical literature citations in the NCBI's PubMed database via the Entrez Programming Utilities (E-utilities).

The PubMed API is officially the NCBI's Entrez Programming Utilities (E-utilities): a suite of eight server-side programs for the Entrez database system. It uses a fixed URL syntax to execute search, link, and retrieval operations against PubMed and 38 other NCBI databases (e.g., Gene, Protein). Developers typically use ESearch to retrieve a list of unique identifiers (PMIDs) from the 39+ million citations, then use EFetch to download full records, often in XML format. Usage requires specifying `tool` and `email` parameters; limit your requests to three per second.

## Recent Public Talks and Demos

### [Agentic Paper Verifier: Citing, Fact-Checking, and Contradicting Drafts with Hybrid Agents](https://poland.aitinkerers.org/talks/rsvp_SKAYDVw8sLY)

I'll demo a an agent that scans a user-drafted paper for uncited statements, inserts "Citation needed" comments, and spins up background jobs for verification. The TS Vercel AI SDK agent does quick scanning and RAG on user library; unsolved claims trigger Python LangGraph workflows for PubMed searches, relevance scoring, and factuality check. Outputs: inline citations, "couldn't find," or "contradicting evidence [citation]."
