How this service works
Fetches structured document summaries for one or more PMIDs via NCBI esummary: title, authors, journal source, publication date, DOI and article IDs as JSON. Enables autonomous biomedical agents and agent-to-agent enrichment workflows to resolve PubMed IDs into full citation metadata keylessly. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.
Output
A JSON object containing structured citation metadata for the requested PMID, including article title, author list, journal source, publication date, DOI, and various article identifiers as returned by NCBI eSummary.
Example use cases
Enrich research pipeline with citation metadata
“I have a list of PMIDs from my literature search — can you pull the full citation info for PMID 33400468, including the title, journal, authors, and DOI?”
Verify paper details before reference list submission
“Before I submit my paper, can you confirm the exact title, publication date, and journal name for PMID 29440439 on PubMed?”
Build structured bibliography for systematic review
“I'm compiling a systematic review and need structured citation metadata for PMID 31860441 — please get me the authors, journal source, publication date, and article IDs.”
Technical details
Endpoint
POSThttps://pubmed-esummary.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need to resolve one or more PubMed IDs into full structured citation metadata (title, authors, journal, date, DOI) without requiring an NCBI API key. It is ideal for biomedical agent workflows, literature enrichment pipelines, or any agent-to-agent workflow where PMIDs must be converted into human-readable or machine-structured bibliographic references at low cost.
Side effects
- Invalid or non-existent PMID returns empty or error result
- NCBI eSummary API downtime causes service unavailability
- Malformed input ID (non-numeric or wrong format) may return no results
- Rate limiting or upstream NCBI throttling could delay responses
- Very recent articles may lack complete metadata (e.g. missing DOI)
