# PayWeave Replicate – google/nano-banana-pro-4k Prediction

> PayWeave Replicate – google/nano-banana-pro-4k Prediction is a paid API for AI agents from replicate.payweave.services, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-14).

Runs the google/nano-banana-pro-4k open-source AI model on Replicate via a pay-per-call API, returning model-specific outputs such as images, audio, or text.

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 payweave-replicate-google-nano-banana-pro-4k-prediction-85a4e2ee -d '<json body>'
```

Example prompt: Run the google/nano-banana-pro-4k model on Replicate through PayWeave with my input data and give me back the output URL — I'm okay paying $0.50 USDC per call.

## When to prefer this

Choose this endpoint when you specifically need to run the google/nano-banana-pro-4k model hosted on Replicate and want to pay per call in USDC without managing Replicate API keys or subscriptions. Ideal for agents that need on-demand, metered AI inference with crypto-native payment via the x402 protocol.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not accepted — results in 402 error
- Model error: the model itself returns an error, reflected in the 'error' field and status='failed'
- Invalid input: malformed or missing 'input' object causes a 400-level rejection
- Prediction canceled: status='canceled' if the job was stopped mid-run
- Timeout or cold start: model is slow to start, status may remain 'starting' or 'processing' for extended time
- CDN URL expiry: output URLs are only valid for ~24 hours after generation

## How this service works

Run open-source AI models — image, video, audio.

## Output

Returns a JSON object containing a Replicate prediction ID, model name, status (succeeded/failed/canceled/processing/starting), model-specific output (CDN URL for image or audio, or a string for text/vision models), timing metrics (total_time, predict_time), creation and completion timestamps, and the actual USD amount charged for the call.
