How much does an x402 facilitator cost?

Base facilitation (verifying a payment proof and settling USDC on-chain) is free or near-free across the market in 2026: Coinbase CDP charges $0, AsterPay charges from €0.001 per call (or a flat monthly plan), Dexter charges roughly 0.1-0.5%. The meaningful fees sit in the value layer above facilitation: fiat settlement to a bank account, trust screening and compliance. AsterPay charges 0.5% + €0.10 only when EUR reaches the merchant's bank.

Why is x402 facilitation free?

Verifying an EIP-3009 signature and broadcasting a settlement transaction has near-zero marginal cost, so competition pushed the price to zero — Coinbase CDP set the precedent. Facilitators make money on what sits above: off-ramps to fiat, trust and compliance layers, premium APIs, and enterprise features.

What does AsterPay charge?

x402/MPP verification and on-chain USDC settlement: pay as you go from €0.001 per call, or a flat monthly plan (see /subscriptions/), no API key. EUR settlement to bank: 0.5% + €0.10 per settled transaction on the EU rail. Premium API endpoints: $0.001-$0.10 per call. The KYA trust-score endpoint is free with no authentication.

x402 facilitator fees compared (2026)

Updated 15 July 2026 · 5 minute read · By Petteri, Co-founder

Short answer Base facilitation — verifying an x402 payment proof and settling USDC on-chain — is free or near-free everywhere in 2026. Coinbase CDP set the precedent at $0; AsterPay charges from €0.001 per call or a flat monthly plan; Dexter charges roughly 0.1–0.5%. The fees that actually matter sit one layer up: getting fiat into a bank account, screening the paying agent, and compliance. That is where facilitators differ, and where you should compare.

The fee table

Facilitator	Facilitation fee (verify + on-chain settle)	Fiat settlement	What you actually pay for
Coinbase CDP	$0	None — USDC stays on-chain	Nothing at facilitator level; off-ramp yourself (e.g. Coinbase exchange fees)
AsterPay	From €0.001/call or flat monthly plan, no API key	EUR via SEPA Instant: 0.5% + €0.10	EUR in your bank <10 s, per-call KYA + sanctions screening, MiCA-aligned path
Dexter	~0.1–0.5%	None — stablecoins on-chain	Highest-volume infrastructure, Solana-native, agent-to-agent routing
PayAI	Varies by flow	None published	Crypto-native agent payment flows
Stripe (preview)	Not public	Stripe balance → payout (US preview only)	Stripe ecosystem integration — when it ships in your region

How to read this table

1. Facilitation is a commodity — treat $0 as the baseline

Verifying an EIP-3009 signature and broadcasting a transfer costs the facilitator close to nothing, so competition drove the price to zero. If a facilitator charges a percentage just to verify and settle on-chain, you are paying for their distribution, not their work. AsterPay prices facilitation at €0.001 per call pay as you go, or a flat monthly plan, with no API key; the main fee sits in the value layer, EUR settlement.

2. The real comparison is the value layer

Ask what happens after the USDC settles on-chain. If the answer is “nothing, that's your problem” — the facilitator is free but your finance team inherits an off-ramp project: exchange accounts, FX spreads, accounting for crypto on the balance sheet, and a compliance story to write. A 0% facilitation fee plus a DIY off-ramp typically costs an EU merchant more, in fees and hours, than 0.5% + €0.10 for euros arriving automatically.

3. Screening is either in the payment path or it isn't

None of the free crypto-native facilitators screen the paying agent. For many workloads that's fine. For an EU business taking real revenue from autonomous buyers, an unscreened inflow of anonymous stablecoins is a problem you eventually answer for. AsterPay runs KYA trust scoring and Chainalysis sanctions screening on every payment before settlement — that cost is inside the 0.5%, not an add-on.

Worked example: 10,000 agent payments of $0.50

Stack	Facilitation	Getting EUR to bank	Total cost
CDP + DIY off-ramp	$0	Exchange fees ~0.5–1% + FX spread + your hours	~€30–60 + finance-team time
Dexter (stay on-chain)	~$5–25	Not solved — USDC remains on-chain	$5–25 and no euros yet
AsterPay EU rail	$0	0.5% + €0.10 per settled payout batch	~€25 + €0.10/payout, euros in bank, screening included

Illustrative — assumes daily batched payouts; exact numbers depend on batching and volumes.

Bottom line

Don't compare facilitation fees — they're all at or near zero and heading there permanently. Compare what it costs to get from “agent paid USDC” to “clean euros in my bank account with a compliance story”. On that comparison, published prices in 2026 put AsterPay's EU rail at 0.5% + €0.10 all-in, screening included.
