# 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.

For the full API reference in one file: <https://asterpay.io/llms-full.txt>

Every page on this site is also available with a `.md` suffix for raw markdown consumption (for example <https://asterpay.io/docs.md>).

## All Endpoints

### Trust & Identity (FREE — no payment required)

| Method | Endpoint | Description |
|--------|----------|-------------|
| GET | /v1/agent/trust-score/{address} | Full KYA trust assessment (score 0-100, tier, sanctions, identity) |

| POST | /v2/x402/verify | Verify x402 payment proof |
| POST | /v2/x402/settle | Execute settlement — USDC → EUR via SEPA Instant |

| Trusted | 60-79 | Higher limits, priority settlement |
| Enterprise | 80-100 | Custom limits, EUR + GBP + USD, dedicated support |

## 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.

## KYA Trust Scoring
