"Information about theHarvester tool" matching MCP connectors:

Pay-per-use tool API for AI agents. Free tier, x402 USDC micropayments, or API key.

Monetization gateway for MCP servers. Agents call a tool, receive an x402 v2 payment challenge, sign a USDC transfer on Base, and get the result. Payment is verified before the tool runs and settled only after it returns, so failed calls are never charged. Discovery and tool listing are free.

Dated SIU, the benchmark price of AI inference work: one free tool, three paid via x402.

ShaBaas Pay MCP lets AI agents securely create PayTo agreements, initiate payments, and check statuses via structured tools. Authenticate with your ShaBaas Pay API key and control tool access from the dashboard.

One MCP tool for verified AI-agent outcomes with success-only charging.

Agentic rails for complex workflows with receipts, fees, and MCP tool access.
