llms.txt

llms.txt is a proposed standard for making website content accessible to large language models. Similar to robots.txt for web crawlers, llms.txt tells AI tools what documentation is available and how to access it.

Files

Binance Web3 API provides two llms.txt files:

File	URL	Description
llms.txt	/en/dev-docs/llms.txt	Summary — document titles, descriptions, and links
llms-full.txt	/en/dev-docs/llms-full.txt	Full content — complete documentation in a single file

Format

llms.txt (Summary)

The summary file contains a structured list of all documentation pages with titles, descriptions, and URLs:

Code
# Binance Web3 API

> On-chain data & trading services for developers.

## Market API

- [Introduction](/market-api/introduction): Market API overview
- [Get Price](/market-api/api-reference/get-price): Real-time token price
