Description
x402-layer helps agents pay for APIs with USDC, deploy monetized endpoints, manage credits/webhooks/marketplace listings, and handle wallet-first ERC-8004 registration/discovery/management/reputation on Base, Ethereum, Polygon, BSC, Monad, and Solana. Optional credentialed flows may use private keys, Solana signer keys, endpoint API keys, PATs, AWAL, or OWS depending on the exact runbook; read-only discovery requires no secrets. Only ask for or use privileged credentials after choosing a runbook that actually needs signing or owner-scoped writes. Use this skill when the user asks to "create x402 endpoint", "deploy monetized API", "pay for API with USDC", "check x402 credits", "consume API credits", "list endpoint on marketplace", "buy API credits", "topup endpoint", "browse x402 marketplace", "set up webhook", "receive payment notifications", "manage endpoint webhook", "verify webhook payment", "verify payment genuineness", "integrate crypto payments into my app", "add USDC payments to my platform", "sell with x402", "build a paywall with webhooks", "register ERC-8004 agent", "register Solana 8004 agent", "submit on-chain reputation feedback", "rate ERC-8004 agent", "use World AgentKit", "unlock human-backed agent wallet discount", "check if an endpoint has an AgentKit benefit", "add API schema to endpoint", "document my API routes", "auto-detect OpenAPI schema", "open support chat", use "Coinbase Agentic Wallet (AWAL)", "OpenWallet", "OWS", "openwallet.sh", or use optional Singularity MCP access with a dashboard PAT to manage x402 Singularity Layer operations on Base, Ethereum, Polygon, BSC, Monad, or Solana networks. Also use this skill to stake $SGL agentically: "stake SGL", "stake $SGL", "unstake SGL", "claim staking rewards", "check my staking position", "stake to run a node", "agentic staking" — sign and submit on-chain Solana staking transactions with a wallet keypair.
