# For AI agents (/for-agents)

These docs are built to be read by tools as well as people.

| Resource | URL | What it is |
| --- | --- | --- |
| `llms.txt` | [`/llms.txt`](/llms.txt) | Index of every page, with a one-line description each. |
| `llms-full.txt` | [`/llms-full.txt`](/llms-full.txt) | Every page, guides and API reference, as one markdown file. |
| Markdown per page | add `.md` to any URL, such as [`/quickstart.md`](/quickstart.md) | One page as markdown. |
| Content negotiation | any page with `Accept: text/markdown` | The same markdown, at the page's own URL. |
| OpenAPI | [`/openapi.json`](/openapi.json) | The Data API's OpenAPI 3.1 schema, generated from the API's code. |

Every page also has **Copy Markdown** and **Open in ChatGPT, Claude or Cursor** buttons under its title.

## Tips for generated code [#tips-for-generated-code]

- Send `OpenGrid-Version: 2026-11-03` on every request, so generated code doesn't change shape under you.
- Read the key from an environment variable. Never paste it into a prompt.
- Branch on `error.code`, not on `error.message`.
- Page with `meta.next_cursor` until it is `null`.
