## 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 article-syndicator-enterprise-content-syndication-websub-publish-d06b300a -d '<json body>'
```

Example prompt: Publish my article titled 'How Decentralized Finance Is Reshaping Global Banking' — the HTML body is the full 600-word piece I just wrote — to Article Syndicator's 101-domain network, listing my author domain as myblog.com and setting the canonical URL to https://myblog.com/articles/defi-global-banking so my original page gets the SEO credit.

## When to prefer this

Choose this endpoint when you need to distribute an existing HTML article to a broad multi-domain network while preserving the SEO canonical link back to your origin site. It is particularly suited for content marketers, PR teams, and publishers who want real-time WebSub push distribution alongside RSS/Atom feed inclusion. Prefer it over simple RSS submission tools when cross-domain canonical attribution (RFC 6596) is a hard requirement and you need simultaneous reach across 100+ domains in a single API call.

## Known failure modes

- Title shorter than 10 characters returns validation error
- Article body shorter than 300 words or containing inline style attributes is rejected
- Invalid or malformed canonicalUrl causes attribution failure
- Unrecognized targetDomain (not in the 101-domain network) returns domain-not-found error
- Payment of $1 USDC not received results in 402 Payment Required
- Missing required fields (title, content, authorDomain, canonicalUrl) returns 400 Bad Request
