For SaaS & APIs

Let AI agents pay your API. Get EUR in your bank.

Shoppers and integrations are becoming AI agents. Make any SaaS endpoint or API agent-payable: agents pay per call in USDC over x402 or MPP, and AsterPay settles real euros to your IBAN via SEPA Instant — in under 10 seconds, no card, no checkout, no human in the loop.

Go live in three steps

No new merchant account, no card-network onboarding. If you can return an HTTP header, you can get paid by agents.

01

Gate your endpoint

Return HTTP 402 with an x402 payment header pointing to AsterPay. Every 402 carries both x402 and MPP headers, so agents use whichever SDK they already have.

02

Agent pays per call

The agent pays in USDC on Base, Polygon, Arbitrum, Optimism or Ethereum. AsterPay scores the payer (KYA) and verifies the payment before your resource is served.

03

You receive EUR

AsterPay settles to your bank in EUR via SEPA Instant in under 10 seconds, through licensed European payment partners. 0.5% per payout.

Why SaaS teams use AsterPay

Pay-per-call, no minimums

Charge $0.001 to $0.10 USDC per call. No subscription, no token, no minimum volume — meter exactly what an agent consumes.

EUR in the bank, not USDC on a wallet

The last mile is the hard part. AsterPay closes it: stablecoins in, euros out to your IBAN, reconciled with a signed receipt.

Trust before settlement (KYA)

Every payer is scored 0-100 on identity (ERC-8004), wallet history and sanctions screening before a cent settles.

Non-custodial, MiCA-aligned

Funds route through licensed PSP/CASP partners, not AsterPay's balance sheet. AsterPay is the technical and trust layer.

SaaS & API FAQ

How do I make my SaaS or API accept AI agent payments?

Return HTTP 402 with an x402 payment header pointing to AsterPay. The agent pays in USDC on Base, Polygon, Arbitrum, Optimism or Ethereum, AsterPay verifies and settles, and you receive EUR via SEPA Instant. Every 402 response also carries an MPP header, so agents can use either SDK.

What does it cost?

Free endpoints (KYA trust score, settlement estimate, merchant resolve) require no payment. Paid API calls cost $0.001 to $0.10 USDC per call via x402 or MPP. EUR settlement costs 0.5% per payout. No subscription, no token, no minimum volume.

Is AsterPay custodial?

No. AsterPay operates a non-custodial architecture; customer funds route through licensed European payment partners (PSP/CASP), not through AsterPay's balance sheet. Settlement is performed by the licensed partner under their MiCA, EMI and PSD2 authorisations.

What currencies can I settle to?

EUR via SEPA Instant is live today, in under 10 seconds. GBP via Faster Payments and USD via ACH are on the roadmap (Q4 2026).
