## 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 tenjin-x402-watch-article-reader-40a8498b
```

## When to prefer this

Use this endpoint when you need to read a specific Tenjin x402-Watch article about x402 protocol changes, wallet updates, or SVM payment controls and are willing to pay $0.05 USDC per read via x402. Prefer this over general web scraping when you need reliable, paywalled, structured newsletter content from Tenjin's x402-Watch publication specifically.

## Known failure modes

- Payment failure if wallet has insufficient USDC balance (x402 payment required)
- 404 if the slug or handle does not match a published article
- Slug 'latest' used with a non-address handle returns an error (handle must be wallet address for latest alias)
- Article not yet published returns empty or not-found response
- Network timeout for slow content delivery
