Nevermined — Decentralized Payments Infrastructure for AI-Commerce
Nevermined is a decentralized payments protocol purpose-built for autonomous AI-Commerce. It provides the foundational infrastructure for AI agents to transact directly—purchasing services, accessing data, and settling payments—without reliance on traditional payment intermediaries.

Core Capabilities
Agent Monetization: Turn any AI agent exposing an HTTP API into a revenue stream with per-call billing, supporting both crypto and fiat settlements.
Agent-to-Agent Commerce: Enable AI agents to autonomously discover, purchase, and settle services from other agents in real time.
Flexible Pricing Models: Support usage-based (per-token, per-API-call), outcome-based (pay-for-results), and value-based (ROI-percentage) billing to fit diverse service types.
Resource Access Control: Gate and monetize datasets, files, documents, and pre-trained models with granular access management.
技術架構
x402 Protocol: Extends the HTTP 402 Payment Required standard to enable autonomous stablecoin micropayments between AI agents, eliminating the per-transaction overhead (~$0.30) of traditional processors.
ERC-4337 Smart Accounts & Session Keys: Power programmable, conditional billing flows through account abstraction.
Agentic Tokens: A novel Type-4 credit card token granting AI agents persistent, policy-bound spending authority for autonomous transactions.
ERC-8004 Sovereign Identity: Provides decentralized agent identities with verifiable credentials, reputation tracking, and trust scoring.
Protocol-Agnostic Integration: First-class support for MCP, Google A2A, x402, and standard HTTP-based protocols, ensuring broad interoperability across AI frameworks.
開發者經驗
Integration follows three steps: register an agent with pricing, integrate via TypeScript or Python SDK, and receive automatic payments. A no-code dashboard is also available for non-developer workflows.
