What is Cra Agent?
Overview
Cra Agent solves the problem of how artificial intelligence agents can directly pay for third-party services without human intermediation. It allows AI systems to request paid APIs, evaluate pricing and terms, and settle payments in USDC through Circle Gateway. The system operates as an MCP server compatible with any LLM client, and as TypeScript libraries published under MIT license, making it accessible to both API consumers and providers.
How it works
When an AI agent requests a paid API endpoint that returns a 402 Payment Required response, Cra Agent reads the price and conditions, checks the operator's spending policy, verifies the seller, and signs a USDC payment using Circle Gateway before retrying the request. Two payment mechanisms are supported: batched nanopayments for per-call APIs that avoid gas fees, and ERC-8183 escrow contracts for larger projects involving an evaluator. API providers can monetize their endpoints with minimal code modifications on Arc.
Token and supply
CRA has a maximum supply of 1 billion tokens. The source material does not describe the token's utility, fees, staking, governance role, or emission mechanics.
