Builder API
For AI agents
Machine-readable docs for AI coding agents and app builders, on this site and on the API host.
Every page here, and the API's own docs, are available as plain text for AI tools.
On this site
| What | Where |
|---|---|
| Index of all pages | /llms.txt |
| All pages in one file | /llms-full.txt |
| One page as Markdown | Add .md or .mdx to the page's URL, or send Accept: text/markdown |
Every page also has buttons to copy it as Markdown or open it in ChatGPT, Claude and other tools.
On the API host
The API host serves docs generated from the same function definitions the API runs, so they are always current. They are public and need no sign-in.

- Coding agents (Claude Code, Cursor, Codex): put
AGENTS.mdin the app's repository, or install the Agent Skill asskills/relynk/SKILL.md. - AI app builders (Replit, Bolt): paste the starter prompt into your first prompt, and add the project knowledge where the builder takes it.
- Lovable: use the custom connector and its knowledge files instead.
All of them describe sign-in with OAuth 2.0 user tokens, as in Authentication.
