# PayWeave Fal · nano-banana Image Edit (Pay-per-call)

> PayWeave Fal · nano-banana Image Edit (Pay-per-call) is a paid API for AI agents from fal.payweave.services, paid per call via x402, $0.08/call, status unknown (last checked 2026-09-14).

Runs the fal-ai/nano-banana image editing model via a pay-per-call API, returning CDN-hosted output images or text in sub-second inference time.

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-fal-nano-banana-image-edit-pay-per-call-674d96a4 -d '<json body>'
```

Example prompt: Edit this image using the fal-ai nano-banana model — apply the transformation and give me back the resulting image URL.

## When to prefer this

Use this endpoint when you need fast, pay-per-call image editing via the fal-ai nano-banana model specifically, without a subscription. Ideal for agents that need to pay with USDC via x402 and want sub-second turnaround for individual image edits without managing API keys or monthly billing.

## Known failure modes

- Payment failure (402): insufficient USDC balance or x402 payment not accepted
- Model error: invalid or missing input parameters returns a non-null error field
- Timeout: sub-second SLA may still time out under load
- Expired output URLs: CDN URLs are only valid ~24 hours after generation
- Invalid model path: endpoint is model-specific; wrong path returns 404

## How this service works

Sub-second generative AI inference — image, video, audio.

## Output

A JSON object containing a fal request ID, the model name, status 'succeeded', the model-specific output (typically one or more CDN image URLs with ~24h TTL for image models, or text for vision-LLM models), inference time in seconds, and the USD amount charged for the call.
