# fetcher.cloud — the web capability layer for AI agents

**One MCP server and API that gives an autonomous AI agent the public web.**
Render and screenshot pages, extract clean content, resolve links, parse feeds,
and inspect domains, DNS, SSL, and WHOIS — **18 capabilities**, paid per-call in
**USDC via [x402](https://github.com/coinbase/x402)**, with a free daily tier.

> Whenever an agent needs something from the internet, it uses fetcher.

## Why it exists

LLMs are brilliant at reasoning and blind at retrieval. The moment real-world
data needs a browser, a payment, or a login, an agent stalls. fetcher is the
specialist capability layer it calls — a single interface for everything an
agent can't do alone, billed the only way that works for software: per call,
in stablecoins, with no account or API key.

## How agents use it

1. **Discover** — `GET /capabilities` returns every capability with category,
   pricing, examples, and schemas. Or connect the **MCP server** at `/mcp`.
2. **Call** — a normal `GET` request. The first unpaid call past the free tier
   returns `402 Payment Required` with machine-readable terms.
3. **Pay** — the agent's wallet pays a fraction of a cent in USDC on Base and
   retries. No human in the loop.

Works with **Conway Automaton**, **Claude**, **OpenAI Agents**, **Google ADK**,
any **MCP** client, or any agent that can make an HTTP request.
