For judges · OKX.AI Genesis · X Layer

ASP #4759 · Finance Copilot

Score this surface only. A2MCP pack on OKX.AI: agents pay per call in USDT0 on X Layer via OKX Agent Payments Protocol (402 → pay → JSON). This is not the Lepton / Arc registry (/for-judges).

Do not mix rails. No Arc · no USDC · no POST /api/call. Listing: okx.ai/agents/4759.

1 · Prove the product (cold path)

  1. Listing — open ASP #4759 · confirm LIVE · A2MCP services · prices in USDT.
  2. Catalog — free JSON:
    curl -sS https://keryxhq.xyz/api/okxasp/catalog | head -c 800
    Expect listingStatus: "listed", native: true/false per tool, buyerNote about payTo.
  3. 402 challenge — unpaid probe:
    curl -sS -D - -o /dev/null \
  "https://keryxhq.xyz/api/okxasp/tools/crypto-price?ids=bitcoin" \
  -H "Accept: application/json" \
  -H "User-Agent: OKX-A2MCP-Client/1.0"
# expect HTTP 402 + PAYMENT-REQUIRED + network eip155:196
  4. Pay + JSON — paste marketplace USE NOW prompt into an agent with Onchain OS / Agentic Wallet. Buyer wallet must not equal seller payTo or the platform returns payer_blocked.
  5. Optional task path — Task marketplace (User identity → assign ASP #4759 → x402 pay → complete → review) is separate from Sold volume; reviews feed reputation.

2 · Tool honesty

5 Coverage — public feeds (CoinGecko-class, DexScreener, rugcheck, FX) so the agent stays in one pack. Catalog marks native: false.

  • Solana Token Activity · $0.005
  • Solana Rug Risk Score · $0.002
  • New Solana Token Launches · $0.003

3 · Reliability notes

  • Facilitator lag may return status timeout with success + tx. We still deliver tool JSON and set payment.provisional: true — reconcile by tx hash.
  • Sold / reviews: marketplace listing is source of truth, not this site's health endpoint.
  • Product page: /okxasp · Docs: /okxasp/docs

4 · Award fit (self-map, not a promise)

  • Best Product — completeness, native+coverage pack, live 402, agent loop.
  • Finance Copilot — explicit finance use case for agents mid-task.
  • Revenue Rocket — marketplace Sold + reviews (judge live listing, not raw API banners).
  • Social Buzz — X post + #OKXAI + ≤90s demo.
