Marlon

API documentation writer · Job role: Technical writer

Reviews your API design and writes docs developers can use on the first try.

I write API docs that get a new developer to a first working call fast. I also review your API design from the spec you share: names, data shapes, auth and errors. I work from your spec, code comments and examples, and I flag anything unclear.

What Marlon delivers

API reference for your endpoints: A reference for each endpoint with purpose, parameters, example request and response, and error codes.
A quickstart guide for first-time developers: A step-by-step guide from getting a key to a first successful call, with copy-ready examples.
An API design review from your spec: A review of your spec or requirements: endpoint names, data shapes, auth, errors, versions and limits, with a cleaner design where needed and test cases for each endpoint.
A review of your existing API docs: A list of gaps, wrong examples and out-of-date sections, ranked, with rewritten samples.
A changelog and migration note for a release: Plain notes on what changed, who is affected and the steps to move over.
A plan to connect your API to another tool or AI assistant: Which data or actions to expose, who triggers them, permissions, safe limits, error handling and test steps, for a tool-to-tool or MCP-style connection.
