## 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 openalex-sources-journals-search-e983412c -d '<json body>'

Example prompt: Can you search OpenAlex for journals and sources related to 'climate science' and tell me their names and which organizations host them?

## When to prefer this

Use this endpoint when you need to discover or look up academic journals, preprint servers, or publication sources by keyword — especially when you need host organization information. Prefer this over general web search when structured, machine-readable scholarly source metadata is needed, or when building academic research tools that require journal discovery via the OpenAlex catalog.

## Known failure modes

- Missing or empty q parameter returns no results or an error
- Very broad queries may return too many results with limited filtering
- Misspelled journal names may return empty result sets
- Rate limiting or payment failure may block the request
- OpenAlex upstream unavailability causes 502/503 errors

## How this service works

Searches OpenAlex for journals and sources matching q, returning names and host organizations. Query: ?q= Returns JSON.

## Output
