Web extraction returns static public pages as clean markdown; every payable operation declares x-payment-info and a 402 response. Free betas: Agent Purchase Guard adds retry-safe purchase intent controls; Outcome Router accepts a desired result plus max budget and autonomously discovers fulfillment, tries zero-dollar proof-of-work first, and supports buyer-signed x402 paid execution where available.\n\nBuyer-signed paid HYDRA execution\n- Outcome request: POST https://earn-tools-backend.onrender.com/outcome-router\n- Paid execution: POST https://earn-tools-backend.onrender.com/outcome-router/execute/{requestId}\n- First execution call returns the relayed Agent402 Smart Order Router x402 PAYMENT-REQUIRED challenge.\n- An x402-capable buyer wallet signs locally and retries with PAYMENT-SIGNATURE.\n- HYDRA forwards the proof and returns the routed result.\n- HYDRA never receives the buyer private key or uses owner working capital.\n- Current beta platform fee: $0.
