API quick start: copy a working script

Pick a model, size and prompt, then copy a ready-to-run script in curl, Python or Node.js. The API is asynchronous: submit a task, poll until it finishes (about 45–100 seconds), download the image. Failed tasks are not charged.

1. Sign in at 72agi.com and open your account page to copy your API key.
2. Top up your balance on the billing page with USDT (beginner guide).
3. Set the key as an environment variable and run the script below.

Prices are per image; most models are the same at 1K, 2K and 4K (image2.5-mid is ¥0.10 at 1K only). Rate limits: 8 single generations per minute (HTTP 429 when exceeded); not enough balance returns HTTP 402. Full reference: API docs · GitHub kit · llms.txt.
