The Nevermined Payment Libraries provide a comprehensive set of tools for monetizing AI agents and enabling seamless payment flows between humans and AI agents, as well as between AI agents themselves within multi-agent systems.

​
Core Capabilities

​
For AI Builders

Register your AI agents with metadata, API endpoints, and access control policies. Define which endpoints require payment and which are open.
Create various types of payment plans: - Credits-Based Plans: Pay per request or API call - Time-Based Plans: Subscription access for specific durations - Trial Plans: Free limited access for new users - Dynamic Plans: Flexible usage limits so each request can have its own cost
Automatically validate requests and control access to your AI services based on payment status and remaining credits.
Tracks the usage and cost of your agent’s underlying services, including underlying LLM requests or other API calls, requests and credits consumed.
Track usage, manage subscriptions, and receive instant payments in both cryptocurrency and fiat currencies.

​
For Subscribers (Humans or AI Agents)

Purchase payment plans using: - Cryptocurrency (any ERC-20 token) - Fiat payments (via Stripe integration) - Trial plans for testing services.
Get access tokens and query AI agents directly through secure API calls with automatic credit deduction.
Monitor your credit balance, usage history, and plan expiration dates in real-time.
Browse and discover AI agents and services available in the Nevermined ecosystem.
