# Use CometAPI docs with LLMs

> Use CometAPI llms.txt and llms-full.txt with coding assistants, retrieval systems, and model prompts.

Use `llms.txt` when you need a compact index of CometAPI documentation pages. Use `llms-full.txt` when your tool can ingest the full documentation text for retrieval, question answering, or coding assistance.

## Fetch the compact index

The following request downloads the CometAPI `llms.txt` index:

```bash theme={null}
curl https://apidoc.cometapi.com/llms.txt
```

The response starts with the documentation title and linked page list:

```text theme={null}
# CometAPI Documentation

> CometAPI developer documentation for unified API access...

## Docs

- [Create a new API key](https://apidoc.cometapi.com/api/api-keys/create-api-key.md)
```

## Fetch the full text

The following request downloads the full text export:

```bash theme={null}
curl https://apidoc.cometapi.com/llms-full.txt
```

The response contains page content grouped by source URL:

```text theme={null}
# Create a new API key
Source: https://apidoc.cometapi.com/api/api-keys/create-api-key

Create a new CometAPI API key for the authenticated account.
```

## Add docs to a retrieval job

The following Python example downloads the full text and writes it to a local file for indexing:

```python theme={null}
from pathlib import Path

import requests

url = "https://apidoc.cometapi.com/llms-full.txt"
response = requests.get(url, timeout=60)
response.raise_for_status()

Path("cometapi-docs.txt").write_text(response.text, encoding="utf-8")
print(len(response.text))
```

The result is the number of characters saved. This is example output only; your value will differ whenever the documentation changes:

```text theme={null}
449946
```

## Common errors

| Error                      | Fix                                                                 |
| -------------------------- | ------------------------------------------------------------------- |
| Tool context is too small  | Use `llms.txt` first, then fetch only the linked pages that matter. |
| Full text is too large     | Chunk `llms-full.txt` by heading or source URL before indexing.     |
| Broken local cache         | Refresh the file during your documentation sync job.                |
| Missing page in AI results | Confirm that the page appears in navigation and in `llms.txt`.      |
