x402 Seller Growth Tools: X402 Seller Action Plan

Overview

Return a seller action plan for directory and conversion improvements. x402-buyer-shortlist first: turn seller route inventory into a buyer-facing shortlist for directory ROI, conversion repair, quote inspection, competitor audits, submission kits, price bands, buyer intent, and action plans. Start buyer evaluation at https://x402-seller.558686.xyz/x402/buyer-use-cases or machine JSON https://x402-seller.558686.xyz/x402/buyer-use-cases.json; checkout contract JSON is https://x402-seller.558686.xyz/x402/checkout.json. Route payment activation JSON is https://x402-seller.558686.xyz/x402/route/x402-seller-action-plan/payment-activation.json. Browsers can inspect the quote, but payment requires a buyer-owned runtime that signs and retries the same request with X-PAYMENT. Buyers can download the route-specific first-payment client at https://x402-seller.558686.xyz/x402/route/x402-seller-action-plan/first-payment-client.mjs, run node first-payment-client.mjs for quote-only checks, then opt into a buyer-owned x402 payment with PAY_REAL_X402=1. Copy-ready first paid request: curl -fsSL https://x402-seller.558686.xyz/x402/route/x402-seller-action-plan/first-payment-client.mjs -o first-payment-client.mjs && npm install @x402/fetch @x402/core @x402/evm @x402/svm viem @solana/kit @scure/base && PAY_REAL_X402=1 EVM_PRIVATE_KEY=$EVM_PRIVATE_KEY node first-payment-client.mjs. Generic clients can also discover it from the live 402 response headers: the standard Payment-Required header includes firstPaymentClient, paymentClientUrl, and sameRequestRetryRequired pointers; X-First-Payment-Client, X-Download-Install-Then-Pay-Command, and Link rel=payment-client mirror the same handoff.
