## Skills

- **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 4 — Official-source data feeds (33 doors)**: Pay-per-call data behind x402/MPP: Stablecoins and crypto, Energy, Company checks, FX, Macro, World risk, Security feeds. 29 paid ($0.001-$0.005 USDC), 4 free. Every response carries source, observed_at (upstream timestamp), cadence and stale. Catalog: GET https://x402.asterpay.io/v1/data.
- **Layer 2 — Merchant Payment Endpoint (MPE)**: The agent has an identifier for the business but not where to send money. GET /v1/mpe/merchants/resolve takes a VAT or company-registry identifier (business_id + business_id_type) or an AsterPay merchant_id and returns the IBAN/BIC on file for merchants registered with AsterPay. POST /v1/mpe/settle additionally accepts a domain (read from its /.well-known/pay.json) or a structured UBL/CII e-invoice URL. Company-name search is not supported. The IBAN is structure- and checksum-checked; bank-side PSD2 Verification of Payee (account-holder name matching) runs at payout with the licensed settlement partner, not here.
- **Prepaid Agent Budget (/budget)**: Give an agent spending money with a hard cap. One USDC transfer (1-500 USDC on Base, 1:1 credit, no platform fee) becomes a prepaid budget token the agent spends per call across every paid AsterPay endpoint. Funding wallet screened against the Chainalysis Sanctions Oracle before issuance. No API key, no card on file, no KYC. Valid 90 days, rollover on request. Setup: claude mcp add asterpay -- npx -y @asterpay/mcp-server — /budget is a native slash command in Claude Code.
- **Layer 3 — Fiat Settlement**: Agent pays in digital dollars. AsterPay converts to EUR and sends an instant SEPA bank transfer in under 10 seconds today. USD (ACH) and GBP (Faster Payments) are on the roadmap (Q4 2026).
