# Morfee > HTML templates plus JSON, a PDF from one API call. Paste HTML and a sample of your JSON into the builder, point at the fields that have to change, and save. From then on one POST with your data comes back as a finished document: the PDF bytes, a download link, or the rendered HTML. Every call needs an API key from /keys, sent as `X-Api-Key` or as `Authorization: Bearer`; a key belongs to one organization and reaches nothing outside it. ## Documentation - [The API, as markdown](https://morfee.furo.solutions/docs.md): the whole thing in one file. Authentication, the three ways to make a document, the template helpers, and what a document is not allowed to fetch. - [OpenAPI 3.1](https://morfee.furo.solutions/openapi.json): every endpoint, derived from the server's own route table, so it cannot be out of date. - [Error codes](https://morfee.furo.solutions/errors): every code an answer can carry, and what to do about each one. Branch on the code, never on the sentence. - [The same documentation as a page](https://morfee.furo.solutions/docs): for a person. ## For an assistant - [The skill](https://morfee.furo.solutions/.well-known/agent-skills/morfee/SKILL.md): how to drive Morfee, written for an agent. Listed at [/.well-known/agent-skills/index.json](https://morfee.furo.solutions/.well-known/agent-skills/index.json), so a client can find it without being told. - [MCP](https://morfee.furo.solutions/mcp): one JSON-RPC endpoint, the same API key, sixteen tools. Reading the library, making documents, folders, versions and the bin; nothing that deletes anything for good. ## Guides - [Power Automate](https://morfee.furo.solutions/power-automate): the HTTP action, its exact settings, what the response looks like, and how to make a retry safe with an idempotency key. - [Quote to PDF](https://morfee.furo.solutions/quote-to-pdf): a bundled worked example, from HTML to finished document. - [Invoice to PDF](https://morfee.furo.solutions/invoice-to-pdf): the same shape as a quote, plus what an invoice template needs beyond it. ## About - [What it costs](https://morfee.furo.solutions/pricing): plans, what is included, and what a document over the bundle costs. - [What it is](https://morfee.furo.solutions/): the product in screenshots, for somebody who has not seen it.
