Minimal docs

Submit any order from an app or coding agent.

One buy-button helper for web apps, one service endpoint for server-side agents, a required spend cap for real orders, and Markdown docs that coding agents can read directly.

2 callable services

LLM coding agent ready

Agent-ready by default.

Works with Codex, Cursor, Claude Code, and any agent that can read Markdown URLs.

Start

Add a buy button

Load checkout.js and call OttoAuth.buy. OttoAuth handles sign-in, confirmation, files, and fulfillment after the click.

Give your agent the skill

Paste it into Codex, Cursor, Claude Code, or another coding agent. It tells the agent exactly which OttoAuth docs to read.

Use API keys for agents

Server-side agents can submit compact work orders to the general order endpoint with dashboard-generated credentials.
