AsterPay primary sources — 2026-05-03

Project status in this pass

  • No canonical standalone AsterPay whitepaper or litepaper surfaced.
  • The clearest current source of truth is the homepage, docs portal, public SKILL.md, and live facilitator / trust-framework endpoints.
  • The project is best understood as an agent trust-and-settlement control plane layered around x402 / MPP payments and optional EUR payout rails.
  • Important nuance: the public marketing and docs portray EUR settlement as a current core product, but the live supported endpoint still labels EUR settlement coming_soon and available: false, so rollout status appears partially in transition.

Primary-source snapshots

1) Official homepage

  • URL: https://asterpay.io/
  • Key excerpt:
    • The homepage says AsterPay is the “only EUR-native x402 facilitator” and presents the core story as “AI agents pay in stablecoins. You get EUR.”
    • It describes a flow where agents settle USDC on-chain and AsterPay handles trust, conversion, compliance, and reconciliation before delivering EUR via SEPA Instant.
    • It also highlights trust tiers, KYA scoring, ERC-8004 identity checks, sanctions screening, and MiCA-aligned positioning through licensed partners.

2) Docs portal

  • URL: https://asterpay.io/docs
  • Key excerpt:
    • The docs describe AsterPay as the trust, discovery, and EUR-settlement layer for AI agent commerce.
    • They say the platform supports x402 + MPP + AP2 compatibility, exposes free trust APIs, and includes optional x402r escrow/refund routing.
    • The API reference shows a much broader product surface than the homepage alone, including agent analysis, market-data endpoints, utility endpoints, settlement endpoints, and facilitator endpoints.

3) Public SKILL.md

  • URL: https://asterpay.io/SKILL.md
  • Key excerpt:
    • The file markets AsterPay as a single-file install for Claude, Cursor, Codex, and other MCP-aware agents.
    • It describes three product layers: TRUST (KYA), DISCOVERY (merchant resolution / MPE), and SETTLEMENT (stablecoin to EUR via SEPA Instant).
    • It also claims 18 MCP tools, 16 of them free, and links to discovery manifests, OpenAPI docs, and compliance posture notes.

4) Live facilitator capability endpoint

  • URL: https://x402.asterpay.io/v2/x402/supported
  • Key excerpt:
    • The endpoint says AsterPay supports x402 exact-scheme payments across several networks and exposes a facilitator description centered on EUR settlement.
    • Crucially, the eurSettlement object says supported: true but status: "coming_soon" and available: false, with a note that “production KYB is in progress” while on-chain USDC settlement is live now.
    • This is the clearest first-party evidence that the fiat-settlement rollout may not yet be broadly live despite stronger language on the homepage.

5) Trust-framework endpoint

  • URL: https://x402.asterpay.io/v1/agent/framework
  • Key excerpt:
    • The endpoint describes a layered agent trust framework: VERIFY, SCREEN, SCORE, SETTLE, and COMPLY.
    • It enumerates concrete score components such as wallet age, wallet activity, Chainalysis sanctions screening, ERC-8004 registry verification, operator KYB, AsterPay transaction history, trust bond, and optional endpoint quality scoring.
    • This is strong evidence that AsterPay is packaging policy and identity infrastructure around payments, not just payment transport itself.

Working conclusion

AsterPay is best cataloged as an AI-agent trust-and-settlement control plane. The deciding evidence in this pass was the combination of KYA scoring, ERC-8004 identity, sanctions screening, dual x402/MPP positioning, merchant/discovery language, and SEPA-oriented payout claims. The main caution is that the marketing copy and live capability endpoint do not fully agree on whether EUR settlement is already live versus still moving through production rollout.
