Talk, don't code
Describe what you need in natural language. Claude knows the base URL, auth format, that POST requests require idempotency, and how to handle errors.
Knows the full API
Endpoints, parameters, invoice types, statuses, lifecycle — Claude knows everything without you passing documentation.
Generates correct code
Typed clients, correct headers, error handling. The code it generates works on the first try.
Always-current docs
The skill points to docs.beel.es/llms.txt to fetch the latest documentation automatically.
llms.txt — Your API, readable by AI
BeeL. publishes an llms.txt file describing the entire API in a format readable by any LLM. Compatible with Claude Code, ChatGPT, Cursor and any agent.
Automatic discovery
Agents read llms.txt to understand what endpoints the API has, what parameters it accepts and how to authenticate.
Always up to date
Auto-generated from the OpenAPI spec. Every new endpoint is instantly available to your AI.
Open standard
Compatible with any LLM agent that supports the llms.txt standard — not just Claude Code.
