A2Agent charges per token consumed, in USD, on a prepaid balance. There is no subscription and no monthly fee. This page explains the rules behind your bill. Per-token rates for each model are published on the A2Agent pricing page and are deliberately not repeated here, so this page can never show you a stale number.

How Billing Works

  • Per-request token counting — Input tokens (your prompt, the system message, and the conversation history you send) and output tokens (the model’s response) are counted separately and billed at their respective rates.
  • Real-time balance deduction — Your balance is deducted immediately after each request completes. Track spend as it happens in the console, or see Usage.
  • No minimum spend — Top up any amount and start making requests right away.
  • Balance never expires — Unused balance stays in your account indefinitely. Inactivity does not burn credits.
