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 with: a unique listing ID, ok: true, the plan name ('month'), the page ID, the featured slug, payment provider ('x402'), duration (30 days), the current status (typically 'paid_pending_review'), and a flag indicating whether approval is required before the listing goes live.
Example use cases
Promote a new blog post
“I just published a new article on markdown.page with page ID 'xyz-789'. Can you buy the one-month featured slot for slug 'devtools-weekly' so it gets more visibility?”
Sponsor a featured slot for a project launch
“I'm launching my open-source project and the page ID on markdown.page is 'proj-launch-42'. Please purchase the monthly featured listing under the slug 'open-source-spotlight' so people find it this month.”
Recurring monthly feature for a newsletter
“Feature my markdown.page newsletter (page ID 'newsletter-99') at the slug 'weekly-reads' for a month — it's time to renew the featured placement.”
Technical details
Endpoint
POSThttps://markdown.page/api/featured/purchase/monthWhen to prefer
Use this endpoint when you need to purchase a featured listing specifically on markdown.page for an existing published page, paid via the x402 micropayment protocol. It is purpose-built for the monthly plan at $29 USDC per call. Prefer this over generic ad-placement APIs when the content is already hosted on markdown.page and you want native featured placement that directs markdown.page readers to that article.
Side effects
- Invalid or non-existent pageId returns an error
- featuredSlug not matching pattern ^[a-z0-9-]+$ causes validation failure
- Payment failure via x402 prevents listing creation
- featuredSlug already taken may result in conflict error
- Malformed requestId (not matching required pattern) causes rejection
- Missing required fields (pageId or featuredSlug) returns 400-level error
