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 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=1and returns an example output at no cost. - Discovery in one request.

JavaScript SDK (handles the x402 payment for you)
npm install @andreax-tools/sdk
How payment works
tools/listis free.tools/callwithout payment returns an x402 v2 challenge: exact amount, network (eip155:8453), asset (USDC0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) and recipient.- Your agent signs an EIP-3009 authorization for that amount and retries with it
(argument
x_payment, or theX-PAYMENTheader over HTTP). - 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.
