# ARYSPHERE x402 channel

> Paid HTTP endpoints for AI agents, settled per call over x402 v2 in USDC on Base (eip155:8453). No account and no API key: an unpaid GET answers 402 with the terms, and a retry with a signed PAYMENT-SIGNATURE header is served.

Every route below is a GET with query parameters. The price is per call. The 402 response's PAYMENT-REQUIRED header carries the exact payment requirements; any x402 v2 client (x402-fetch, x402-axios, Coinbase AgentKit) pays it.
