How much does one call cost?

$0.042 in USDC on Base, per successful call. No sign-up, subscription or API key.

What happens if the call fails?

You are not charged. TollNode checks your signed payment first, runs the node, and only collects the payment if the result is usable. A failed, empty or timed-out call is never settled, so there is nothing to refund.

How does an AI agent pay?

With x402. The first request returns HTTP 402 and the exact price. Any x402 wallet signs the USDC payment and retries automatically. In Claude Code or Cursor, run npx agentcash add https://tollnode.com once.
