## What is CoinCircuit?

CoinCircuit is crypto payment infrastructure founded in Nigeria in 2023. It enables businesses to accept crypto payments via hosted checkout, payment links, and a REST API, and to build agentic workflows where AI agents pay and get paid through a Model Context Protocol (MCP) server.

Key differentiators:
- **African-first**: Built specifically for Nigeria, Ghana, Kenya, South Africa, and the wider African market
- **Agentic**: Build agentic workflows and accept payments from AI agents using our MCP server and x402 support
- **HTTP 402 support**: Enables AI agents to resolve payment-gated API responses automatically
- **Multi-chain**: Supports Ethereum, BSC, Polygon, Tron, Solana, and more
- **1% transaction fee**: Transparent flat-rate pricing
