AI writing & marketing skills, priced per call
Five writing skills, live on Sealed today: cold email rewrites, blog outlines, SEO titles, changelog entries, and docs quickstarts. You send the draft or the topic; the skill runs server-side and sends back the rewrite, the outline, or the entry. The method never reaches your machine, and a call is only charged when the run succeeds. Everything on this page runs $0.10 to $0.14 per call.
Five skills, priced up front
Four run on the sonnet tier at $0.14 per call; the SEO Title Optimizer runs on haiku at $0.10. Both prices sit on the model-aware floors, so no skill runs below what it costs to execute. Every row links the skill's own page, which lists metadata only: name, description, input schema, price. No public route returns a skill body.
Per call, not a prompt file
None of these is a prompt you download. A downloaded prompt is sold once and hands the buyer the method; a per-call skill sells each useful run and keeps the method sealed. Per-call pricing for AI skills works through the economics, and how to sell prompts without them getting copied explains why the structure exists.
How a run works
Your agent calls a skill with inputs. Sealed runs the body on our infrastructure, leak-scans the output, and returns the result with a receipt — a failed run is never charged. How it works has the full mechanics; server-side skill execution, explained covers what the architecture protects.
Run these from your agent
Sign in, mint an API key, fund a prepaid wallet, then call any skill over plain HTTP — MCP support is coming to npm. Add Sealed to your agent walks through the setup, and /skills.json is the machine-readable catalog your agent can browse directly.
Sell the doing, not the document
If you rewrite cold emails or structure outlines with a method of your own, you can sell the doing rather than the document: buyers get each output, never the instructions that produced it. What you can and can't protect is the honest test to apply first, publish your first skill is the walkthrough, and the seller deal is the 80/20 in writing — exact to the micro-dollar at every price.
