Discover, browse, filter and (optionally) pay for x402-compatible API endpoints and MCP tools; supports pay-per-call USDC payments on Base.
This skill lets agents discover x402 Bazaar services (machine-readable payable APIs), inspect pricing and network details, and optionally pay per-call using USDC on Base. It automates the 402 payflow: discover, read 402 response, pay via a facilitator, then retry with proof to receive the paid result. Typical uses include finding weather, inference, or market-data endpoints and executing low-cost paid calls without pre-shared API keys.
Activate when you need to find a payable API or MCP tool (eg: "find weather APIs", "services under 0.01", "call this x402 endpoint"). Use Browse-only mode for discovery without keys; enable Pay mode (EVM_PRIVATE_KEY in .env) when executing paid calls. Not for wallet balance checks or listing as a seller.
Works with agents that can run Python / shell commands and manage env secrets (Claude Code, OpenClaw/agents that support Python-based skills).
