Proxies.sx sells metered 4G/5G mobile and residential proxy traffic from a GB balance priced at $4/GB, down to $2.40/GB at volume; traffic in cheaper exit countries uses less balance, from $0.75/GB at list. Access is through one gateway credential or dedicated modem ports. It says it runs its own carrier modems in six countries plus an opt-in, paid peer network, with devices on sale in about 50 countries. It targets AI agents with an MCP server and account-less USDC payment via x402. No operating company is named.

Trial & refunds

The smallest purchase is 0.1 GB ($0.40) through the x402 USDC flow, at $4 per GB of traffic in every country; the account path lists 1-24 GB of balance at $4/GB. No refund policy is published; the agent Pool Gateway documentation states that unused GB are not refunded, and the terms say unused bandwidth may be forfeited on termination.
