## 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 pubmed-trends-snapshot-14fc11f1 -d '<json body>'
```

Example prompt: Give me a snapshot of the current trending research topics on PubMed so I can see what biomedical subjects are getting the most publication activity right now.

## When to prefer this

Use this endpoint when you need a real-time snapshot of trending biomedical and medical research topics from PubMed, particularly for research intelligence, competitive landscape analysis, or monitoring emerging science areas. Prefer this over manual PubMed searches when you want aggregated trend data rather than individual paper lookups.

## Known failure modes

- Payment failure if USDC balance is insufficient (x402 payment required before response)
- PubMed upstream unavailability causing empty or stale snapshot
- Rate limiting if too many consecutive calls
- Invalid request body causing 400 error
- Worker timeout if PubMed data retrieval takes too long

## Output

A snapshot object containing trending topics, publication frequency data, and research activity patterns extracted from PubMed biomedical literature at the time of the call.
