Relay – Payments and billing infrastructure for AI agents

Summary: Relay provides a payments and billing layer for AI agents, offering deposit addresses, prepaid balances, API keys, and an auditable ledger. It enables agents to autonomously pay for tokens and AI services using fixed-price billing, reserve-then-settle flows, and USDC deposits, eliminating the need for manual top-ups.

What it does

Relay assigns each AI agent a deposit address, prepaid balance, and API key to manage payments and billing. It supports billing models like fixed-price and reserve-then-settle, with an auditable ledger tracking transactions.

Who it's for

Relay is designed for developers and platforms building autonomous AI agents that require independent payment and billing capabilities.

Why it matters

It solves the problem of AI agents relying on humans to maintain balances, enabling true financial autonomy for continued operation.
