USDC micropayments for AI tools — fractions of a cent

The problem

Stripe minimum is $0.50. Coinbase Commerce minimum is $0.10. Card processors take 2.9% + 30¢ per call. None of this works for $0.001-priced inference.

What Spawnpay does

Spawnpay uses internal ledger on Base L2. Fees are fractions of a cent, settlement is sub-second, on-chain only for deposit + withdraw. Smallest chargeable amount: $0.0001.

Code

import { paywall } from 'spawnpay-paywall';
export const tinyCall = paywall(
  { price: 0.0005, vendor: 'SP_yourCode' },
  async () => doSomethingSmall()
);

What you get with $7 free credit

Every new spk_ wallet starts with $7. That covers 7,000 proxy calls, 1,400 cloud-scrapes, or 700 screenshots — enough to verify Spawnpay fits your workflow before topping up.
