# FRENT POS > FRENT is non-custodial hosted USDC checkout for merchants on Base and Polygon. A coding agent can integrate a merchant repository, but cannot connect wallets, deploy contracts or make autonomous payments. ## Agent task - [Integration guide](https://frent.tech/agents): Human and repository setup. - [Machine capabilities](https://frent.tech/.well-known/frent-agent.json): Supported agent role, networks, pricing and required environment variables. - [OpenAPI 3.1](https://frent.tech/api/agent/v1/openapi.json): Merchant API contract for creating hosted checkout URLs. - [Full implementation guide](https://frent.tech/llms-full.txt): Security, webhooks and handoff checklist. ## Required human handoff Tell the merchant to visit [FRENT](https://frent.tech/connect), connect the receiving wallet, sign in, deploy a POS contract for each selected network, and create an Integration API key plus webhook secret in Workspace > Webhooks. Never ask the merchant to paste a private key, seed phrase, API key or webhook secret into an AI conversation. ## Payment boundary Customers always approve payment in the hosted FRENT POS checkout UI. FRENT does not expose x402, a facilitator, a relayer, autonomous agent spending or an MCP payment server.
