## 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 logos-by-readia-edit-article-7af8e49d -d '<json body>'
```

Example prompt: Update my Logos by Readia article (ID 123) — change the title to 'Bitcoin in 2025', set the price to $0.25, and update the categories to ['Technology', 'Crypto'].

## When to prefer this

Use this endpoint when a user wants to modify an existing article they own on the Logos by Readia marketplace — changing its title, HTML content, price, or categories. Prefer this over re-publishing when the article already exists and only needs updating rather than creation.

## Known failure modes

- Article ID not found or not owned by the paying wallet — authorization error
- articleId is missing from the request — validation error
- Price outside allowed range ($0.01–$1.00) — validation error
- Payment of $0.01 USDC via x402 fails or is rejected — payment error
- Invalid HTML in content field — parsing or validation error
- Network or blockchain transaction failure — transient error
