Messages base

agent402.tools · x402

Anthropic Messages API over x402 - point the Anthropic SDK (or Claude Code / the Agent SDK) at base_url https://agent402.tools/v1 and pay $0.02 per call in USDC, no API key, no signup. Same models, caps and price as this tier's /chat/completions route; any model here is served through the Messages wire (Claude natively, others translated). Depth: `effort` (low..max) on Claude 4.7+ and Haiku 5.5, thinking.budget_tokens on older Claude.

x402: an unpaid request gets a 402 with the price and pay-to wallet. addrbook never pays.
