Payments for AI agents: Atto, Nano, USDC and Lightning compared
An AI agent needs one data lookup. The price is $0.001. Before the provider can return a result, the agent needs a way to pay that leaves the sale worth making.
We build Atto for small, direct agent payments: no protocol transfer fees, first-party MCP, CLI and n8n integrations, and public node access. Its wallet tools are available today; a complete paid-HTTP service still needs custom payment logic.
USDC brings dollar pricing and existing x402 support. Lightning serves bitcoin payments through L402. Nano offers another feeless option with community agent tools. For AI agent micropayments, the useful choice depends on the service, the payment size and the integration you want to run.
