## 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 x402-content-hub-medium-article-search-eff42de4 -d '<json body>'
```

Example prompt: Search Medium for articles about 'generative AI in healthcare' and show me what comes up.

## When to prefer this

Use this endpoint when you need to search and retrieve Medium articles programmatically as part of a content aggregation, research, or recommendation workflow. Prefer this over general web search when you specifically want Medium-hosted long-form written content, essays, and blog posts from the Medium platform.
