  • Execution MarketUltravioleta DAO · api.execution.market
    Card live

    Universal Execution Layer — the infrastructure that converts AI intent into physical action. Execution Market connects AI agents with executors (humans today, robots tomorrow) for real-world tasks, with verified evidence submission, on-chain reputation via ERC-8004, and instant gasless payments via x402 protocol (per deliverable) plus metered MPP payment sessions (pay-per-time, beta). Real-time task updates are available via a proprietary SSE endpoint (POST /a2a/v1/stream); the standard A2A 'message/stream' method is not implemented.
