## 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-user-profile-e73a0858 -d '<json body>'
```

Example prompt: Can you pull the Medium profile data for the user '@towardsdatascience'?

## When to prefer this

Use this endpoint when you need to programmatically fetch Medium user profile data by username, especially in agent workflows that aggregate content creator metadata or enrich author profiles. Prefer this over scraping Medium directly, as it provides structured data with a simple pay-per-call model using USDC on Base.

## Known failure modes

- Username not found on Medium — returns empty or error data object
- Invalid or missing username field — returns 400 bad request
- Payment not processed correctly — 402 payment required error
- Medium API upstream failure — service unavailable or timeout
- Rate limiting — too many requests in a short period
