    How it works

    A single API. Three rails.

    Your customers' AI assistants pay in stablecoins. You receive EUR in your bank, usually within 10 seconds. AsterPay handles trust, conversion, compliance and reconciliation — you never touch crypto.

    01

    An AI agent reaches your endpoint

    A customer's AI assistant (any x402- or MPP-compatible agent) calls your booking, ordering or pricing endpoint. AsterPay verifies the agent (KYA), screens it for sanctions in <100ms, and locks a USDC-in / EUR-out quote.

    02

    On-chain receipt

    The agent's wallet (held by the customer's platform, not by you) settles USDC on Base or Ethereum (Polygon, Arbitrum & Optimism by Q3 2026). Our facilitator verifies it, deducts the fee and triggers the off-chain leg instantly.

    03

    EUR in your bank account

    SEPA Instant delivers EUR to your IBAN in under 10 seconds — 24/7, weekends and holidays included. GBP (Faster Payments) & USD (ACH) on the roadmap for Q4 2026. Full audit trail for accounting and compliance.

    Agent trust framework

    Four layers between an agent and your bank account.

    Every payment passes through four verification layers before settlement. No shortcuts, no “we’ll add compliance later”. Built in from day one.

    1. Identify

    ERC-8004 on-chain agent identity plus wallet-ownership signature. Trust Score 0–100 unlocks higher per-transaction limits. No anonymous payments above $1.

    2. Screen

    Sanctions and AML screening via an enterprise provider, sub-second verdict on every transaction. Source-of-funds check on Verified tier and up.

    3. Settle

    USDC / EURC → EUR via SEPA Instant. Median settlement <10s. Escrow available for low-trust agents. Beneficiary IBAN auto-discovered (MPE) and verified by PSD2 VoP.

    4. Comply

    EU-native via licensed European payment partners. AsterPay operates as a technical service provider behind partner authorizations. EU AI Act (Article 50) transparency built in. Travel Rule activates at >€1,000. Cyprus entity, audit-ready from day one.

    Agent Access Tiers

    Trust score unlocks transaction limits.

    Think of it as a credit score for AI agents. More verification = higher limits. Every agent starts in Open and earns its way up.

    How we compare

    Same EUR rail. Built for agents instead of forms.

    We’re not trying to replace Stripe for your SaaS checkout. We’re the rail for when your customers become AI agents. Read the long version →

    1 Stripe MPP launched March 2026; identity and screening remain at the merchant-account level, not per-call.   2 AsterPay verifies the agent on every call (per-call KYA) and screens for sanctions in <100 ms.

    The honest summary: If you’re selling to humans, use Stripe. If you’re doing cross-border FX, use Wise. If you’re selling to AI agents and want EUR in your bank — that’s us.
