## 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 synthora-doaj-open-access-article-search-761360c6 -d '<json body>'
```

Example prompt: Search the DOAJ open-access article index for peer-reviewed papers on CRISPR gene editing and give me the titles, authors, DOIs, abstracts, and full-text links for the top results.

## When to prefer this

Choose this endpoint when you need legally free, peer-reviewed academic literature with guaranteed open-access full-text links and no authentication overhead. It is ideal for autonomous agents that cannot handle OAuth or API key flows, for agent-to-agent research pipelines, or when you specifically need DOAJ-indexed content (which guarantees open-access compliance). Prefer it over general web search when citation-quality metadata (DOIs, ISSNs, structured abstracts) is required.

## Known failure modes

- Empty result set if query terms are too narrow or obscure
- Partial metadata if the DOAJ record lacks an abstract or full-text link
- Upstream DOAJ API unavailability causing service errors
- Malformed query input returning an error or empty response
- Rate limiting or payment failure returning a non-200 response
