# Access DuyuSense content from AI agents and code

Everything on this site is available in machine-readable form: a public read-only REST API, an MCP server, an A2A agent, Markdown versions of every page and llms.txt. No registration or API key is required.

## Markdown for agents

Request any page with Accept: text/markdown and you receive a clean Markdown version (with an x-markdown-tokens header). Browsers still get HTML. Every page also links its Markdown twin via rel="alternate" type="text/markdown".

## llms.txt

[/llms.txt](https://www.duyusense.com/llms.txt) lists the most important pages with one-line summaries; [/llms-full.txt](https://www.duyusense.com/llms-full.txt) contains the full text of all pages in Markdown.

## REST API (read-only)

Base URL https://www.duyusense.com/api/v1. Endpoints: GET /pages, GET /pages/{id}, GET /search?q=...&lang=en, GET /company, GET /health. OpenAPI 3.1 description: [/openapi.json](https://www.duyusense.com/openapi.json); catalog: [/.well-known/api-catalog](https://www.duyusense.com/.well-known/api-catalog) (RFC 9727).

## MCP server

Streamable HTTP endpoint https://www.duyusense.com/mcp (stateless, JSON responses). Tools: search_duyusense, get_page, list_solutions, get_company_info. Server card: [/.well-known/mcp/server-card.json](https://www.duyusense.com/.well-known/mcp/server-card.json).

## A2A agent

JSON-RPC endpoint https://www.duyusense.com/a2a (message/send). It answers questions by retrieving the relevant DuyuSense guides. Agent card: [/.well-known/agent-card.json](https://www.duyusense.com/.well-known/agent-card.json).

## Agent skills

Skill index for agents: [/.well-known/agent-skills/index.json](https://www.duyusense.com/.well-known/agent-skills/index.json) (fiber sensing technology selection, querying DuyuSense knowledge, preparing a project enquiry).

## WebMCP

In browsers that support WebMCP, the site registers in-page tools (search, page retrieval, contact details) through document.modelContext.

## Authentication and use

All endpoints are public, anonymous and read-only; see [/auth.md](https://www.duyusense.com/auth.md). Content may be used for search, AI answers and training with attribution to DuyuSense (www.duyusense.com). Please keep automated traffic reasonable.
