Pricing
Credit-based subscriptions: 1 Credit = 1 PDF render. Free credits are issued monthly, subscription Credits renew monthly, packs never expire — and they are spent in that order.
- Free · $020 Credits per month, reset monthly; 5 renders per day, 1 concurrent. Sign up and start — no payment needed.
- Starter · $9/mo500 Credits per month, reset monthly; 4 concurrent renders; every capability unlocked.
- Pro · $29/mo3,000 Credits per month, reset monthly; 4 concurrent renders; built for high-volume agent pipelines.
- Credit pack · $5 one-time250 Credits that never expire; stacks with any plan and carries you over when monthly Credits run out.
Deduction order
Every render deducts from: free bucket → subscription bucket → pack bucket. Failed renders
cost nothing; when you're out, the API returns insufficient_credits (HTTP 402) with your
remaining balance, so the agent can decide what to do next.
Guardrails, same for every plan
- Up to 50 pages per PDF; Markdown source up to 1 MB; 60-second render timeout.
- Built-in Templates and Front-matter brand controls are available on every plan.
Payments & tax
Subscriptions and packs are settled through Creem (Merchant of Record): Creem processes the payment, issues receipts and handles sales-tax and VAT compliance as the merchant of record — payment details never touch Serifmark servers. Upgrades, downgrades and refunds follow the Terms of Service.
