}FAQ
- What does the Grok Imagine image generation node return?
- xAI's image model: vivid, photorealistic images and edits from a prompt, at a low flat price.
- How much does one call cost?
- $0.028 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.
- Can I use an API key instead?
- Yes. Create a free account, add funds in USDC on Base, create an API key and send it as Authorization: Bearer. Each successful call is deducted from your balance at the same price; failed calls cost nothing.
