Samples
Action samples
Layer 1 — Check Agent Trust Score (KYA)
Score any AI agent 0-100. Identity (ERC-8004), wallet history, sanctions screening (Chainalysis), third-party attestations. Higher trust = higher payment limits.
Layer 2 — Merchant Payment Endpoint (MPE)
The agent knows the company name but not where to send money. AsterPay finds the merchant's payment details automatically from multiple sources and verifies the account matches the company. Now the agent knows exactly where to pay.
Layer 3 — Fiat Settlement
Agent pays in digital dollars. AsterPay converts to local currency and sends an instant bank transfer. EUR via SEPA, USD via ACH, GBP via Faster Payments. Same pattern, any currency. Under 10 seconds.

# AsterPay
> Trust, discovery, and EUR settlement layer for AI agent payments. Accepts both x402 (Coinbase) and MPP (Stripe/Tempo) on every paid endpoint. USDC/EURC in, EUR to bank — EUR via SEPA Instant in under 10 seconds today; GBP (Faster Payments) and USD (ACH) on the roadmap. EU-native via licensed partners; CASP authorization in preparation. Operated by AELIRA LTD (Cyprus).
The fastest way to learn AsterPay is the single-file skill at <https://asterpay.io/SKILL.md>. Read it once and your agent can install the SDK, run trust checks, resolve merchants, and settle EUR.

## Three Product Layers
1. **TRUST (KYA)** — Know Your Agent: ERC-8004 identity, Chainalysis sanctions screening, Trust Score 0-100, behavioral analysis
2. **DISCOVERY (MPE)** — Merchant Payment Endpoint: agent sends company name → AsterPay finds IBAN/BIC from 5 sources → Verification of Payee (PSD2) confirms account
3. **SETTLEMENT** — USDC/EURC → EUR via SEPA Instant (<5 sec), smart routing across 4 providers, MiCA-compliant
## Merchant Payment Endpoint (MPE) — Discovery
| Method | Endpoint | Description |

| GET | /v1/mpe/merchants/resolve?business_id={id}&business_id_type={type} | Find merchant bank details from company ID (VAT, LEI, DUNS) |
| POST | /v1/mpe/merchants | Register merchant with IBAN + Verification of Payee |
| GET | /v1/mpe/merchants/{id} | Get merchant details |
| POST | /v1/mpe/settle | Full flow: resolve → VoP → KYA → quote → SEPA Instant |
| GET | /v1/mpe/settle/{id} | Check settlement status |
MPE resolves the "agent knows the company name but not where to pay" problem. No other x402 facilitator offers merchant discovery.
