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 payment via x402, with a unique listing ID, the plan name ('quarter'), page ID, featured slug, duration of 90 days, current status ('paid_pending_review'), and a flag indicating that editorial approval is required before the listing goes live.
Example use cases
Promote a developer tutorial for a quarter
“Feature my markdown.page article with page ID 'intro-to-agents' under the featured slug 'ai-agents-tutorial' for the full 90-day quarter plan.”
Sponsor a product announcement page
“I want to buy a 90-day featured slot on markdown.page for my page ID 'product-launch-2025' — use the featured slug 'new-launch' so people can find it in the featured section.”
Boost visibility for an open-source project page
“Purchase the quarter featured plan on markdown.page for the page 'open-source-toolkit' with featured slug 'dev-tools', and use my contact email dev@example.com for the listing.”
Technical details
Endpoint
POSThttps://markdown.page/api/featured/purchase/quarterWhen to prefer
Use this endpoint when you want to pay for a 90-day promotional featured listing for an existing markdown.page page. Choose this over shorter plans if the user wants maximum sustained visibility. This is specifically for markdown.page's featured placement product and requires an existing published page on the platform, not for initial page creation or one-time publishing.
Side effects
- Invalid pageId — page does not exist on markdown.page
- featuredSlug does not match required lowercase alphanumeric pattern
- Payment failure via x402 protocol
- Duplicate requestId — idempotency key already used
- articleUrl is malformed or not a valid markdown.page URL
- Featured slug already taken by another page
- Approval rejected after payment — listing does not go live despite successful payment
