## 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 replicate-via-locus-x402-fd075b85 -d '<json body>'
```

Example prompt: Use the black-forest-labs flux-schnell model on Replicate to generate an image of a golden retriever playing in the snow — pass the prompt as the model input.

## When to prefer this

Choose this endpoint when you need to run any of thousands of open-source models on Replicate without managing your own API keys or subscriptions — especially useful for agents that need pay-per-call billing via x402/USDC, access to niche or cutting-edge open-source models, or want to avoid Replicate account setup overhead.

## Known failure modes

- Invalid model_owner or model_name returns an error or empty result
- Malformed or missing input parameters cause inference failure
- Insufficient USDC balance or payment authorization failure blocks the request
- Model-specific input schema mismatch causes a 400-level error
- Long-running models may require polling the statusUrl for completion

## How this service works

## Output
