x402 gets agents to pay. AsterPay gets you paid in EUR.
The protocols move stablecoins between machines. We turn that into money in a European bank account, with the trust and compliance layer agents do not bring with them.

Questions agents and builders ask.
What is AsterPay?
AsterPay is the EUR settlement layer for AI agent payments. It is an x402 facilitator that converts USDC, EURC and EURCV stablecoins from any chain to EUR via SEPA Instant in under 10 seconds, with settlement performed by licensed European payment partners. GBP via Faster Payments and USD via ACH are on the roadmap (Q4 2026).
How do I accept x402 payments in euros?
Use AsterPay as your x402 facilitator and EUR settlement endpoint. Your API returns HTTP 402 with an x402 payment header pointing to AsterPay; the agent pays in USDC on Base, Polygon, Arbitrum, Optimism or Ethereum, and AsterPay pays you EUR via SEPA Instant. KYB onboarding takes 10 minutes through Sumsub. No per-transaction KYC, no manual off-ramp.
What is an x402 facilitator?
An x402 facilitator is the trusted party that verifies and settles a HTTP 402 payment. It checks the payment proof, executes the on-chain settlement, and forwards the result to the resource server. Coinbase CDP runs the default facilitator on Base. AsterPay runs an EU-native facilitator that adds EUR settlement (via licensed European payment partners), KYA trust scoring and ERC-8004 identity attestation on top of the standard x402 flow.
How do I convert USDC to EUR for AI agents?
Send USDC to AsterPay's settlement endpoint and we convert it to EUR via licensed CASP partners and pay your bank account through SEPA Instant. AsterPay supports USDC, EURC and EURCV on Base, Polygon, Arbitrum, Optimism and Ethereum. End-to-end latency is under 10 seconds.
What is KYA (Know Your Agent)?
KYA (Know Your Agent) is AsterPay's open trust-scoring framework for AI agents in payment flows. It scores any agent wallet 0-100 across seven components: wallet age, wallet activity, sanctions screening, ERC-8004 identity, operator KYB, transaction history and trust bond. KYA is the agent-payments equivalent of KYC for humans.
How does AsterPay compare to Stripe for AI agent payments?
Stripe is built for human checkout flows; AsterPay is built for autonomous AI-agent payments. Stripe requires merchant accounts, card-network fees and 2-7 day settlement. AsterPay accepts stablecoin payments via x402 and MPP, settles to EUR via SEPA Instant in under 10 seconds, and includes KYA trust scoring. Use Stripe if your customer is a human; use AsterPay if your customer is an AI agent.
How do I integrate AsterPay?
Three ways: (1) MCP server — npm install @asterpay/mcp-server — for any LLM agent that speaks MCP. (2) Python SDK — pip install asterpay — for Python agents. (3) Direct HTTP API at x402.asterpay.io for any language. Free endpoints (KYA trust score, settlement estimate) require no auth. Paid endpoints accept either x402 or MPP payment proofs. Full docs at asterpay.io/docs.
What payment protocols does AsterPay support?
AsterPay supports six agent-payment protocols natively: x402 (Coinbase HTTP-402 standard), x402r (escrow + refund extension), MPP / Machine Payments Protocol (Stripe and Tempo open standard), AP2 (Google Agent Payments), A2A (agent-to-agent) and ERC-8004 (on-chain agent identity). Every 402 response includes both x402 and MPP headers, so agents use whichever SDK they already have installed.
What chains and stablecoins does AsterPay accept?
AsterPay accepts stablecoin payments on five EVM chains with native USDC: Base, Polygon, Arbitrum, Optimism and Ethereum. Supported stablecoins include USDC, EURC and EURCV. Bitcoin Lightning is also live for sub-cent micropayments. All payments settle to EUR via SEPA Instant today; GBP (Faster Payments) and USD (ACH) settlement is on the roadmap (Q4 2026).
Is AsterPay regulated in the EU?
AsterPay operates through AELIRA Ltd (EU entity) and is built on a non-custodial architecture: customer funds never touch AsterPay's balance sheet. Off-ramps run through licensed CASP partners under MiCA, with KYB onboarding via Sumsub. AsterPay operates as a technical service provider; settlement is performed by licensed European payment partners under their MiCA, EMI and PSD2 authorisations.
How much does AsterPay cost?
Free endpoints (KYA trust score, settlement estimate, merchant resolve, market data) require no payment or auth. Paid API endpoints cost $0.001 to $0.10 USDC per call via x402 or MPP. EUR settlement costs 0.5% per transaction. No subscription, no token, no minimum volume.
How does an AI agent pay a business when it only knows the company name?
Through AsterPay's Merchant Payment Endpoint (MPE). The agent sends the company name or VAT number to GET /v1/mpe/merchants/resolve, which resolves the payee only from provable sources and returns the IBAN/BIC with logged provenance and a confidence level. Full IBAN validation runs on every resolve; bank-side PSD2 Verification of Payee is performed by the licensed settlement PSP before payout. POST /v1/mpe/settle then chains resolve, payee validation, KYA trust check, USDC-to-EUR conversion and SEPA Instant payout in one call. Resolution is free.
Does AsterPay have a native token?
No. AsterPay has no native token, no on-chain governance, no airdrop, no presale, and no plans for any of these. Customers pay in USDC, EURC, EURCV or fiat. There is no $ASTERPAY, $ASTER, or any other AsterPay-issued token in existence or in the roadmap.
Is AsterPay related to Aster (ASTER) DEX?
No. AsterPay is not affiliated with Aster (ASTER) DEX, the BNB Chain perpetual exchange. AsterPay is operated by AELIRA LTD (Cyprus, HE 490977) and is an EUR settlement and trust layer for AI agent commerce on the x402 (Coinbase) and MPP (Stripe/Tempo) protocols. AsterPay has no native token, no $ASTER, no on-chain governance, and no presence on BNB Smart Chain. Different company, different product, no token.
