Tools and snippets
OpenAPI, generated clients, copy-and-paste helpers, and coding agents.
- The playground Try the REST API, the MCP server and signed embed tokens in your browser. Sample data needs no account, a playground key reads your own organization, and you can paste a key of your own.
- OpenAPI and typed clients Download Halo's OpenAPI file, generate a typed TypeScript client with openapi-typescript and openapi-fetch, or import it into Postman or Bruno.
- Snippets Copy-and-paste helpers for the Developer API in cURL, JavaScript, Python and Go. The auth header, keyset paging, and retries that follow Retry-After.
- Use Halo with coding agents Point Cursor or Claude Code at these docs with llms.txt, connect the Halo MCP server so they can see your data, and keep keys out of prompts and repositories.
- Planned features What's planned for the Developer API after its first version, including service keys, write scopes, webhooks from Halo Data, IP allowlists, SDKs and a CLI. None of it exists yet.
