## 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 rotary-agency-doaj-free-source-data-api-f77a6717
```

Example prompt: Search DOAJ for open access journals in the field of climate science and return their titles, ISSNs, and publishers.

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to DOAJ journal and article metadata without setting up your own DOAJ API key, particularly in agentic workflows that require on-demand open-access journal verification or discovery at low cost.

## Known failure modes

- Missing or invalid query parameters may return empty result sets
- DOAJ upstream unavailability could cause timeouts or error responses
- Overly broad queries may return paginated results requiring further calls
- Non-existent ISSNs return empty or not-found responses
- Rate limiting or payment failure results in 402 response
