## 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 markdown-page-featured-purchase-weekly-slot-9011f649 -d '<json body>'
```

Example prompt: Can you purchase a one-week featured slot on markdown.page for my page ID 'abc123', listing it under the featured slug 'my-awesome-guide'?

## When to prefer this

Use this endpoint when you have an existing markdown.page page and want to pay for a one-week featured promotion slot under a specific slug. This is the right choice when the goal is content promotion and discovery on the markdown.page platform specifically, funded via x402 crypto payment. It is not for creating new pages, for featured placements longer or shorter than a week, or for promotion on other publishing platforms.

## Known failure modes

- Invalid or non-existent pageId — page must already exist on markdown.page
- featuredSlug not matching the required pattern (lowercase alphanumeric and hyphens only)
- Payment failure via x402 — insufficient funds or unsupported wallet
- requestId not matching required pattern or duplicate requestId causing conflict
- articleUrl not a valid public markdown.page URL
- Featured slug already taken or unavailable for the requested week

## How this service works

Publish Markdown to a public URL. Browsers receive HTML; command-line tools and agents receive plain text. No account or API key required.

## Output

Returns a JSON object confirming the purchase, including a unique purchase ID, the plan ('week'), the pageId and featuredSlug, a status of 'paid_pending_review' indicating human approval is required before the page goes live as featured, the duration in days (7), and a flag confirming approval is required.
