# PayWeave Replicate — google/nano-banana-2-2k Model Inference

> PayWeave Replicate — google/nano-banana-2-2k Model Inference is a paid API for AI agents from replicate.payweave.services, paid per call via x402, $0.22/call, status unknown (last checked 2026-09-15).

Runs the google/nano-banana-2-2k open-source AI model on Replicate via pay-per-call USDC micropayment, returning model-specific output such as images, audio, or text.

## 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 payweave-replicate-google-nano-banana-2-2k-model-inference-747699bd -d '<json body>'
```

Example prompt: Run the google/nano-banana-2-2k model on Replicate through PayWeave and give me the output — here's my input object: {"prompt": "a glowing tropical fruit in neon light"}.

## When to prefer this

Choose this endpoint when you need to run the specific google/nano-banana-2-2k model on Replicate without a Replicate account or subscription, paying only per prediction in USDC via x402. Prefer this over direct Replicate API access when you want micropayment-based billing or are operating in an agent environment that supports x402 payments natively.

## Known failure modes

- Model inference fails — status returns 'failed' with a non-null error field
- Payment rejected or insufficient USDC balance — x402 payment handshake fails before prediction starts
- Input schema invalid — model rejects malformed or missing input fields
- Model is unavailable or cold-start timeout — status may return 'starting' or 'canceled'
- CDN URL expires after ~24h TTL making output inaccessible if not saved promptly

## How this service works

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

## Output

Returns a Replicate prediction result object containing: a unique prediction ID, the model identifier, a status (succeeded/failed/canceled/processing/starting), any error message, model-specific output (CDN URLs for images or audio with ~24h TTL, or a string for vision-LLM models), timing metrics (total_time, predict_time), creation and completion timestamps, and the USD amount charged for the call.
