What Counts as an API Call

Each request to a billing-eligible endpoint counts as one API call. The following endpoints are free and do not count toward your quota:

• GET /v1/templates
• GET /v1/usage
• GET /v1/documents
• GET /v1/documents/:id

Demo publish (POST /v1/demo/publish) does not require authentication and has no quota.

API Cost

The API is computationally inexpensive. Markdown-to-HTML conversion is a server-side text transformation with no GPU, external API, or database-heavy operations. This makes it possible to offer generous free tier limits.

Estimated cost per 1,000 API calls: $0.001 to$0.004 (serverless compute only).

When to Upgrade

Consider upgrading to Pro when:

• You need more than 3 documents.
• You want access to all 63 templates.
• You are making more than 1,000 API calls per month.
• You need custom URL slugs for published pages.
• You want to hide the Unmarkdown™ badge.
• You need file downloads (DOCX, HTML, PDF).

Demo Publish: Always Free

The Demo Publish endpoint requires no authentication and has no usage limits. Demo pages expire after 72 hours. This is ideal for:

• Trying the API before committing to an account.
• LLM agents that need to publish quickly.
• One-off document sharing without signup.

To keep a demo page permanently, claim it with an authenticated account.

Frequently Asked Questions

Is there overage pricing?
No. When you reach your monthly quota, API calls are rejected with a 429 error until the quota resets on the 1st of the next month. There are no overage charges.

Do read endpoints count toward my quota?
No. GET requests for templates, usage, and documents are free and do not count.

Can I use the API on the Free tier?
Yes. Free accounts get 1,000 API calls per month with 10 req/sec rate limiting.

Is there a separate API pricing tier?
No. API access is bundled with the Free and Pro plans. There is no standalone API plan.
