[Z333Q]

Add P402 Router

Service: P402 Router — OpenAI-compatible AI router with per-request micropayment billing
URL: https://p402.io
npm package: @p402/mpp-method@0.1.0

What it does

Routes AI inference requests to 13 LLM providers (OpenAI, Anthropic, Gemini, Groq, etc.) with intelligent cost/speed/quality selection. Payment accepted via:

• Tempo (USDC.e, TIP-20) — primary rail
• Base (EIP-3009 USDC/EURC) — secondary rail

mppx integration

Uses @p402/mpp-method (published today) — a first-party mppx payment method package with baseCharge (EIP-3009) and p402Charge (multi-rail) methods. Authorization: Payment header accepted on POST /api/v2/chat/completions.

import { Mppx } from 'mppx/server';
import { p402Charge } from '@p402/mpp-method';

const mppx = Mppx.create({
  methods: [p402Charge],
  secretKey: process.env.MPP_SECRET_KEY!,
});

Checklist

• id is unique (p402)
• All ServiceDef fields present and typed correctly
• status: "beta" (launched today)
• integration: "first-party" (direct mppx integration via @p402/mpp-method)
• payments: [TEMPO_PAYMENT] (USDC.e on Tempo, primary rail)
• realm: "p402.io" (P402 issues its own MPP challenges)
