How this service works
817 pay-per-call APIs for AI agents. Every endpoint is POST /<name> and is payable in USDC over x402 on Base and Solana — no signup, no API key, just pay-per-call. GET https://x402.agentutility.ai/ returns the same catalog as machine-readable JSON.
Output
Returns a JSON object containing: the echoed query string, a search object with total matching papers count, number returned, and an array of paper PMIDs and titles, a summary object with style ('bullets') and a multi-line bullet-point synthesis of the retrieved papers, a boolean 'degraded' flag indicating partial failures, an array of internal component timings (pubmed-search and summarize-text steps), a disclaimer clarifying this is not medical advice, and a 'composed_of' list of sub-services used.
Example use cases
Drug efficacy literature review
“Pull the latest PubMed papers on metformin and cardiovascular outcomes in type 2 diabetes — summarize the top 5 findings in bullet points.”
Rare disease research overview
“Search PubMed for studies on Huntington's disease gene therapy and give me a brief summary of up to 8 papers.”
Clinical guideline evidence check
“Find peer-reviewed literature on mRNA vaccine safety in immunocompromised patients and summarize the key findings from the top 5 papers.”
Technical details
Endpoint
POSThttps://x402.agentutility.ai/pubmed-brief?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to rapidly survey biomedical literature on a specific topic without maintaining a PubMed API key or building a multi-step search+summarize pipeline. It is ideal for research assistants, clinical decision-support agents, or scientific writing tools that need a quick evidence snapshot. Prefer it over raw PubMed API access when you want both retrieval and synthesis in a single pay-per-call step. Not suitable for downloading full-text papers, real-time clinical advice, or queries requiring more than 10 papers.
Side effects
- Query exceeds 300 character limit — truncation or rejection
- max_results out of range (must be 1–10) — validation error
- PubMed API unavailable — degraded=true with partial results
- Summarization step fails — degraded response with search results only but no summary
- No papers found for query — empty papers array and empty summary
- Malformed query syntax — zero or unexpected results returned
