What is tx402.ai?

tx402.ai is an x402 payment gateway for agent-native EU LLM inference. AI agents pay per-request with USDC on Base — no API keys, no accounts, no KYC. Wallet = authentication.

• OpenAI-compatible API — drop-in replacement (/v1/chat/completions, /v1/models)
• USDC micropayments on Base — x402 protocol with dynamic per-model pricing
• SSE streaming — full streaming support for real-time responses
• EU-sovereign — GDPR-compliant, zero data retention, EU infrastructure (Tensorix)
• Agent-friendly discovery — llms.txt, ai-plugin.json, .well-known/x402, OpenAPI 3.1

How agents use it

import { wrapFetchWithPayment } from "@x402/fetch";
import { ExactEvmScheme } from "@x402/evm";

const paidFetch = wrapFetchWithPayment(fetch, signer, [new ExactEvmScheme()]);

const res = await paidFetch("https://tx402.ai/v1/chat/completions", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    model: "deepseek/deepseek-v3.2",
    messages: [{ role: "user", content: "Hello from an autonomous agent" }],
  }),
});
