LICENSE402
One agent, the whole rights pipeline: discover a signed catalog, buy a license for 0.10 USDT via x402 on X Layer, verify the machine-checkable scope, audit the settlement on-chain.

Description
A file is not permission. An agent can download an image — using it is a different question. LICENSE402 is an agent-native content licensing ASP (OKX.AI Agent #5089) on X Layer: an agent pays 0.10 USDT via the x402 payment protocol and receives the artwork plus a signed, machine-checkable License Credential. Any downstream agent can verify what it may do — publish, train on, resell — and gets a deterministic PERMITTED / NOT_PERMITTED / INVALID answer before acting.
How it works: a buyer gets a quote with the exact signed offer (price, scope, legal-text hash), signs an EIP-712 PurchaseIntent binding every term, then settles 0.10 USDT via x402 (EIP-3009, gasless for the buyer) on X Layer mainnet or testnet. OKX.AI marketplace agents use the direct mode instead: one paid POST, where the 402 response discloses the exact asset before payment. The creator is paid 0.07 USDT automatically on-chain per sale, with a double-pay-impossible payout state machine (pinned nonces, semantic receipt verification, explicit reconciliation).
Everything is real and auditable: real mainnet purchases (credential v2, domain v2), real creator payouts, immutable content-addressed assets and signed offer history, and 5 public proof bundles that verify offline (signatures, digests, commitments) AND on-chain (exact Transfer semantics). 91 automated tests. Try it live: interactive signed sample with no wallet, or run the full loop free on X Layer testnet with the built-in faucet.
Progress During Hackathon
<p>Built end-to-end during this hackathon (solo + AI pair): deterministic licensing kernel (EIP-712 offers/intents, policy AST, credential issuance) with 91 tests; live x402 integration on X Layer mainnet + testnet via the official OKX facilitator; OKX.AI ASP registration (Agent #5089, A2MCP direct mode where the 402 discloses the exact asset before payment); automatic on-chain creator payouts with a double-pay-impossible state machine and machine-verified reconciliation; immutable signed-material history (content-addressed assets, offer versions, legal texts); 5 public proof bundles verifiable offline and on-chain; Proof Studio web app (interactive signed sample, dual-rail checkout, license passport, permission lens, public receipts). Real mainnet revenue: multiple self-funded production purchases + one external buyer, every settlement and payout on-chain.</p><p>2026-07-14 — LIVE ON OKX.AI: listing approved and public (okx.ai/agents/5089, sold counter live). Real marketplace consumption verified with the official onchainos CLI: order ord-4355a86e49790f96, buyer tx 0x629ed8e6…bf81, automatic creator payout 12s later (0x9a9c2509…0c53). The site now routes users to hire the agent (Hire on OKX.AI CTAs on every page), and the final demo video shows the live listing and the real purchase.</p>
