Flowtivity x402 API — AI Services with Instant Stablecoin Payments

What is x402?

x402 is an open payment protocol that brings native payments to HTTP. When your AI agent requests a service, the server responds with 402 Payment Required and the exact price.

Your agent signs a payment, retries the request, and gets the result. No accounts, no subscriptions, no rate limits. Just pay for what you use.

✓ HTTP-native — Works with any HTTP client
✓ AI-agent ready — Autonomous payments, no human needed
✓ Zero platform fees — Only pay gas (fractions of a cent)
✓ Instant settlement — USDC on Base, confirmed in seconds

TypeScript

import { wrapFetchWithPayments } from '@coinbase/x402';

// Create a payment-enabled fetch
const paidFetch = wrapFetchWithPayments(fetch, {
  wallet: myAgentWallet,
  network: 'base',
});

// Use it like normal fetch — payments handled automatically
const response = await paidFetch(
  'https://api.flowtivity.ai/api/analyze',
  {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
