# For AI agents & LLMs

> How AI assistants and agents can read the Crius documentation (llms.txt, llms-full.txt, Markdown pages) and call the Crius API (OpenAPI document, anonymous endpoints).

Source: https://crius.sh/docs/ai/

The Crius documentation is built to be read by language models as easily as by people.

| Resource | URL | Use |
|---|---|---|
| `llms.txt` | [`https://crius.sh/llms.txt`](https://crius.sh/llms.txt) | Index of the docs with one-line summaries ([llmstxt.org](https://llmstxt.org) format) |
| `llms-full.txt` | [`https://crius.sh/llms-full.txt`](https://crius.sh/llms-full.txt) | All documentation in one Markdown file |
| Markdown pages | `https://crius.sh/docs/<page>.md` | Any docs page as clean Markdown, e.g. [`/docs/quickstart.md`](https://crius.sh/docs/quickstart.md) |
| OpenAPI 3 | [`https://api.crius.sh/openapi.json`](https://api.crius.sh/openapi.json) | Machine-readable endpoints and parameters, for tool or function definitions |

Every docs page also has a **Copy page** button that copies its Markdown, ready to paste into a chat.

## Giving an agent access to the API

- Core endpoints (prices, token profiles, pools, trades, candles, search, stats) work **without a key**, so an agent can explore at 2 requests per second.
- For anything more, create a dedicated API key for the agent with only the `read` scope, an IP allow-list if it runs on a fixed host, and a per-key rate limit. Rotate or revoke it from the dashboard at any time.
- Responses are compact JSON with plain decimal numbers and a `meta.block` that lets the agent cite exactly which block its answer reflects.

## Suggested system prompt snippet

```text
You can call the Crius API (https://api.crius.sh) for Robinhood Chain (chain id 4663) data.
Docs: https://crius.sh/llms.txt. Send the key in the x-api-key header.
Token price: GET /v1/robinhood/token/{address}/price. Token profile: GET /v1/robinhood/token/{address}.
Candles: GET /v1/robinhood/token/{address}/candles?interval=1h. Search: GET /v1/robinhood/search?q=.
Amounts are in human units, USD values are plain decimals, timestamps are unix milliseconds.
