# Dopamint AI Image Generation (nano-banana)

> Dopamint AI Image Generation (nano-banana) is a paid API for AI agents from x402-dev.dopamint.ai, paid per call via x402, $0.0527/call, status down (last checked 2026-09-14).

Generates images from text prompts using the nano-banana model, returning a job ID and status URL for async retrieval

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-dev-dopamint-ai-60e56e30 -d '<json body>'
```

Example prompt: Generate an image of a futuristic city at sunset with flying cars, in 16:9 aspect ratio, output as PNG, using seed 42 so I can reproduce it later.

## When to prefer this

Choose this endpoint when you need fast, cost-effective image generation using the nano-banana model specifically, and you are comfortable with an async job-polling pattern. Prefer nano-banana-pro or stable-diffusion-v35-large siblings if you need higher quality or different stylistic output. This is a good fit for lightweight creative tasks or when cost per generation matters ($0.0527 USDC).

## Known failure modes

- Missing required 'prompt' field returns a validation error
- Invalid aspect_ratio value (not in allowed enum) returns a bad request error
- Model unavailability or overload may delay or fail job creation
- Payment not completed or insufficient USDC balance returns a payment-required error
- Invalid output_format value returns a bad request
- Requesting more images than allowed may be silently capped when limit_generations is true

## How this service works

Generate image using nano-banana

## Output

Returns a job ID, a status tracking URL, a human-readable message with the URL, an ISO 8601 timestamp, and an HTTP status code. The image itself must be fetched asynchronously via the returned statusUrl once the job completes.
