# SiteCheck PubMed Search

> SiteCheck PubMed Search is a paid API for AI agents from api.sitecheck-api.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).

Searches PubMed for biomedical research articles by keyword, returning titles, authors, journals, DOIs, and publication dates.

## Facts

- Endpoint: GET https://api.sitecheck-api.workers.dev/api/pubmed?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sitecheck-pubmed-search-d434546e
```

Example prompt: Search PubMed for recent articles about GLP-1 receptor agonists published from 2022, and give me up to 15 results with their titles, authors, and journal names.

## When to prefer this

Choose this endpoint when you need structured, attributed biomedical literature from PubMed with filtering by publication year and result count. It wraps NCBI's eUtils API with a simple pay-per-call interface, ideal for agents that need to surface peer-reviewed studies without managing NCBI API keys or rate limits directly.

## Known failure modes

- Missing required 'q' parameter returns an error
- Invalid or non-numeric 'from' year may cause unexpected results
- Limit values outside 1-20 may be rejected or clamped
- Network or NCBI upstream outage may cause timeout or empty response
- Very broad queries may return large total counts but only return 'limit' articles

## How this service works

PubMed articles matching words, optionally from a year: PMID, title, first five authors, journal, date, DOI and link. Two NCBI requests. Attribution: PubMed (NCBI). Information only, not medical advice.

## Output

Returns a JSON object with the search query echo, total matching article count, data source attribution, and an array of articles each containing PubMed ID, DOI, publication date, article title, author list, journal name, and a direct PubMed link. Also includes a timestamp and a disclaimer that the information is not medical advice.
