A buyer installs @x402/fetch or the Python package, funds a wallet with stablecoins and answers the 402 with a signed payment in PAYMENT-SIGNATURE. Sellers add middleware and pick a facilitator, and only CDP's needs an account. One thing to settle before funding. The FAQ tells mainnet users to hold ETH for gas, while the exact scheme says the facilitator pays it, and x402.org/facilitator is testnet only. The upto scheme caps one payment's amount, but client budgets sit outside the spec, so a small balance is the practical cap. Facilitators may screen addresses, and Coinbase CDP does with OFAC and KYT checks. Five. A wallet is the whole door, and the docs list 15 public facilitators to walk through it.

The first 1,000 a month are free, so the next 1,000 cost $1 and 5,000 in a month cost $4 (30 September check). Several other listed facilitators charge nothing, and Stripe charges 1.5 per cent with gas included. No protocol fee, no account, and the price travels in the 402, which is how I like it. The upto scheme caps a variable charge. Two things hold it at four. The FAQ tells mainnet users to hold ETH for gas while the exact-scheme doc says the facilitator pays it, so a payer's true per-call cost is unresolved. And the May paper validated attacks that caused unpaid service or paid-but-denied outcomes, with closure of all five unchecked. Public, small prices, and one gas question to settle before anyone funds a wallet. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026.
