Nevermined Payments Integration

Overview

Nevermined provides financial rails for AI agents — real-time monetization, access control, and payments. This skill gives you everything needed to:

• Protect API endpoints with the x402 payment protocol
• Charge per-request using credit-based billing
• Integrate with Express.js, FastAPI, Strands agents, MCP servers, or Google A2A agents
• Support subscriber-side flows (purchase plans, generate tokens, call protected APIs)
• Enable agent-to-agent payments via the Google A2A protocol

The x402 protocol uses HTTP 402 responses to advertise payment requirements. Clients acquire an access token and retry the request. The server verifies permissions, executes the workload, then settles (burns credits).
