## 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 ciel-m2m-api-marketplace-mm-hf-micro-service-f18714ce
```

Example prompt: Call the CIEL mm-hf micro-service with my properties payload and return the parsed result — charge the 0.5 USDC fee to my Base wallet.

## When to prefer this

Prefer this endpoint when you need a lightweight, pay-per-call AI micro-service accessible via x402 USDC micropayments on Base, especially when integrating into autonomous agent workflows that require no subscription setup and on-demand inference or data transformation from a Hugging Face-backed model.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Malformed or missing properties string returns error or empty result
- Endpoint unresponsive due to bare-IP hosting instability
- Ambiguous input schema leads to unexpected or generic output
- Rate limiting or subscription cap exceeded on RapidAPI side
