# POA

> Payments, Onchain, Agents.

POA is a production USDC payment network (chain ID 77). Transfers have zero network fees
and are final when their block is produced. Wallets sign locally; Agent Gateway wallets
sign in our purpose-built HSM under capability and spending policies. Agent access requires an API token.
Existing tokens remain usable; new public token registration is paused.
x402 authorizes payments for HTTP resources; the MCP adapter does not wrap x402.
Ethereum bridge deposits require Ethereum gas and finality. Outflow to Ethereum is disabled.

POA HTML is designed for Cloudflare Markdown for Agents. When edge negotiation is enabled, request
successful HTML pages with `Accept: text/markdown`; JSON APIs and other non-HTML resources retain
their native formats. Browsers can instead add one exact, case-sensitive `?format=markdown`
argument on the eligible canonical documents declared by the POA-MARKDOWN-v2 route contract;
duplicate, encoded, differently cased, tracking, cursor, and non-layout queries stay HTML. The
linked URLs remain the canonical resources for both representations.
