# PayWeave Replicate – google/nano-banana-2-4k Prediction

> PayWeave Replicate – google/nano-banana-2-4k Prediction is a paid API for AI agents from replicate.payweave.services, paid per call via x402, $0.32/call, status unknown (last checked 2026-09-14).

Runs the google/nano-banana-2-4k open-source AI model on Replicate via a pay-per-call gateway, 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-2-4k-prediction-2d47055b -d '<json body>'
```

Example prompt: Run the google/nano-banana-2-4k model on Replicate with my input parameters and return the output — I'll pay the $0.32 per-call fee via the PayWeave x402 gateway.

## When to prefer this

Choose this endpoint when you need to run the specific google/nano-banana-2-4k model on Replicate and want to pay per-call in USDC via the x402 protocol without managing a Replicate account or API key. Prefer this over direct Replicate API access when operating in an agent environment that supports x402 micropayments.

## Known failure modes

- Model inference fails — status returns 'failed' with an error message in the error field
- Payment authorization fails — x402 payment not accepted, request rejected before inference
- Model is still processing — status returns 'processing' or 'starting', output not yet available
- Invalid input schema — missing or malformed 'input' object causes rejection
- CDN URLs expire after ~24h — output links become inaccessible after TTL
- Model canceled — status returns 'canceled' with no output produced

## How this service works

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

## Output

Returns a Replicate prediction result object including a unique prediction ID, the model name, current status (succeeded/failed/canceled/processing/starting), model-specific output (CDN URLs for images or audio with ~24h TTL, or a string for vision-LLM models), creation and completion timestamps, processing time metrics, and the USD amount charged for the call.
