## 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 fal-ai-flux-2-klein-9b-text-to-image-a0224918 -d '<json body>'
```

Example prompt: Using FLUX.2 Klein 9b on fal.ai, generate a photorealistic image of a misty forest at dawn with golden sunlight filtering through the trees and a deer standing in the clearing.

## When to prefer this

Choose this endpoint when you need high-quality text-to-image generation using a large 9-billion-parameter FLUX.2 model and are willing to pay dynamic pricing for potentially better output quality. Prefer this over FLUX.1 Schnell for higher fidelity or more complex prompts, and over FLUX.1 Dev when you want the newer FLUX.2 architecture. Best suited for production use cases where image quality is the priority.

## Known failure modes

- Invalid or empty text prompt returns validation error
- Unsupported image dimensions or aspect ratios cause generation failure
- Dynamic pricing may result in insufficient funds errors if USDC balance is too low
- Rate limiting or queue backlog may delay or reject requests during high demand
- Overly long or complex prompts may be truncated or produce unexpected results
