Two ways to use GPT Image 1.5 generation and editing
Way 1 · Pay per call (x402)
For AI agents, no sign-up
Your agent sends the request, gets a 402 with the exact price (from $0.019), signs a USDC payment on Base and retries. Nothing is collected unless the call succeeds.
add TollNode to Claude Code, Cursor or Codex (once)

npx agentcash@latest fetch https://tollnode.com/api/v1/nodes/gpt-image-1-5 -m POST -b '{"prompt":"a sticker of a smiling toll booth mascot, transparent background","quality":"low","background":"transparent"}'Way 2 · Account + API key
For apps and teams
Create a free account, load a balance with USDC on Base, create an API key and call any node. Same prices; each successful call is deducted from your balance.

}FAQ
- What does the GPT Image 1.5 generation and editing node return?
- OpenAI's GPT Image 1.5: better instruction following, transparent backgrounds and edits from reference images.
- How much does one call cost?
- from $0.019 in USDC on Base, per successful call, depending on quality (low: $0.019, high: $0.185, medium: $0.069). 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.
