llms.txt

Make Caesar's documentation accessible to AI coding assistants

Caesar’s documentation supports llms.txt, a standard for exposing documentation to AI developer tools like Cursor, GitHub Copilot, ChatGPT, and Claude.

What is llms.txt?

When AI coding assistants access documentation, they typically receive HTML pages full of navigation, styling, and other markup. This wastes tokens and reduces context quality.

llms.txt solves this by providing:

  • Markdown instead of HTML: 90%+ reduction in token usage
  • Structured summaries: Each page distilled to a one-sentence description
  • Hierarchical organization: AI tools can understand your documentation structure

Available endpoints

EndpointDescription
/llms.txtLightweight summary with page descriptions and URLs
/llms-full.txtComplete documentation content in Markdown

Use /llms.txt for discovery and navigation. Use /llms-full.txt when you need the AI to understand specific implementation details.

Using with AI tools

Cursor

Add Caesar’s documentation to your Cursor context:

  1. Open Cursor settings
  2. Navigate to Features → Docs
  3. Add https://docs.caesar.org/llms.txt

Now you can reference Caesar documentation in your prompts with @Caesar.

Claude / ChatGPT

Paste the llms.txt URL directly in your conversation:

Read https://docs.caesar.org/llms-full.txt and help me integrate Caesar's research API into my Python application.

GitHub Copilot

Reference the documentation in your comments:

1# See https://docs.caesar.org/llms.txt for Caesar API documentation
2# Implement a function that creates a research job with auto mode

Query parameters

Filter the output to reduce tokens further:

ParameterDescriptionExample
langInclude only specific SDK language?lang=python
excludeSpecExclude OpenAPI specification?excludeSpec=true
Python-only documentation
$curl https://docs.caesar.org/llms.txt?lang=python
Exclude API spec
$curl https://docs.caesar.org/llms-full.txt?excludeSpec=true

Hierarchical access

Access llms.txt at different documentation levels:

/llms.txt                              # Full documentation summary
/documentation/get-started/llms.txt    # Get Started section only
/api-reference/llms.txt                # API Reference only

The comprehensive /llms-full.txt is only available at the root level.

Example output

llms.txt format
# Caesar API Documentation
> Caesar is an agentic research API that transforms questions into comprehensive, citation-backed answers.
## Get Started
- [Introduction](/): Overview of Caesar's research capabilities
- [Authentication](/documentation/get-started/authentication): API key generation and usage
- [Rate Limits](/documentation/get-started/rate-limits): Concurrency and monthly limits
## Integration
- [SDKs](/integration/sdks): Python and TypeScript client libraries
- [OpenAI Compatibility](/integration/openai-compatibility): Use OpenAI SDK with Caesar
...

Best practices

Start with the summary

Use /llms.txt first to help the AI understand what’s available, then drill into specific pages.

Filter by language

If you’re working in Python, use ?lang=python to exclude irrelevant code examples.
