## Description
270 pay-per-call AI tools for agents, paid via x402 (USDC on Base). No signup, no API keys.

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "andreax": {
    "command": "npx",
    "args": ["-y","andreax"]
  }
}
```

## Documentation & README

# Andreax — pay-per-call AI tools for agents (MCP + x402)

**Remote MCP server:** `https://pagos.andreax.dev/mcp` (Streamable HTTP, JSON-RPC)

Andreax is a remote MCP server with 270 pay-per-call tools for AI agents — text, code, documents,
audio, web research and on-chain data. There is no signup and no API key: each call is paid
individually with [x402](https://www.x402.org/) in USDC on Base, from $0.001 per call.

- **No accounts, no keys.** The payment is the authentication.
- **Gasless for the payer.** EIP-3009 `transferWithAuthorization`; the settlement gas is paid by Andreax.
- **Free preview.** Every tool accepts `?sample=1` and returns an example output at no cost.
- **Discovery in one request.** `GET https://pagos.andreax.dev/.well-known/x402.json`

> This repository only contains the public listing (README + directory metadata). The server itself
> is hosted; there is nothing to install.

## Connect

### Claude Desktop / Cursor / any MCP client (via `mcp-remote`)

```json
{
  "mcpServers": {
    "andreax": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://pagos.andreax.dev/mcp"]
    }
  }
}
```

### Clients with native remote-MCP support

Add a remote server with URL `https://pagos.andreax.dev/mcp` (transport: Streamable HTTP, auth: none).

### JavaScript SDK (handles the x402 payment for you)

```bash
npm install @andreax-tools/sdk
```

## How payment works

1. `tools/list` is free.
2. `tools/call` without payment returns an **x402 v2 challenge**: exact amount, network
   (`eip155:8453`), asset (USDC `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) and recipient.
3. Your agent signs an EIP-3009 authorization for that amount and retries with it
   (argument `x_payment`, or the `X-PAYMENT` header over HTTP).
4. The result comes back together with the on-chain settlement reference.

Your agent only needs a wallet with a little USDC on Base — no ETH.
