The short answer: at the root of the documentation there is an llms.txt file: a plain-text index of every page, in both languages, each with a link to its Markdown version and a sentence about what it covers. At the end, a link to the OpenAPI specification. It is the quickest way to get an AI assistant working from our documentation rather than from what it thinks it knows.
What the file contains
| Part | What it says |
| Header | The Interweb name, the API base address and a note that every page has a Markdown version. |
| Documentação em português | Every page in Portuguese, with its .md link and description. |
| Documentation in English | The same, in English. |
| Specification | The link to the OpenAPI specification. |
How to use it with an assistant
|
|
|
A well-written request
The more precise the request, the less the assistant makes up. An example:
Read the llms.txt of this documentation and the API rules and SMS pages.
Write a Python function that sends an SMS through the API.
The key comes from the RLX_API_KEY environment variable.
Always send Idempotency-Key and wait for Retry-After after a 429.
Use only operations that appear in the documentation.
| Never paste your API key into a conversation with an assistant. It does not need it to write the code; the key only goes into the environment where the program runs. And check the result: if the assistant uses an operation that is not on the "What the API does today" list, that operation does not exist. |
| What llms.txt is in general, and whether it is worth having on your own website, is covered in llms.txt: what it is. |

Open the index and see how it is laid out. Open llms.txt |
