# Coding Agents

> Set up Claude Code, Cursor, GitHub Copilot, or Codex with the Egon documentation and OpenAPI schema, so they write code that matches the Egon API.

Set up **Claude Code, Cursor, GitHub Copilot, or Codex** to write code that matches the Egon API.

## Add the Project Instructions

Coding agents read an instructions file in your repository. Add this block to `AGENTS.md` (Codex, Cursor, GitHub Copilot) or `CLAUDE.md` (Claude Code):

```text
## Egon API

- Documentation index: https://documentation.egon.com/llms.txt (add .md to any page URL for its markdown)
- OpenAPI schema: https://documentation.egon.com/openapi.json
- Authentication: use the header described in securitySchemes in the schema.
- Read the API key from the EGON_API_KEY environment variable. Never hardcode it and never call Egon from the browser.
- Check the quality indicators in each response before trusting the data: https://documentation.egon.com/docs/quality-indicators.md
```

## Generate a Client

Then ask for what you need, for example:

```text
Using the Egon OpenAPI schema at https://documentation.egon.com/openapi.json,
write a typed TypeScript client for the endpoints this project uses.
```

For prompts on specific integrations, see the [Prompt Library](https://documentation.egon.com/docs/build-with-ai/prompt-library.md). To give your agent the same rules as an installable skill, see [Agent Skills](https://documentation.egon.com/docs/build-with-ai/skills.md).
