## 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 nvidia-nim-riva-translate-api-via-x402-806b9081 -d '<json body>'
```

Example prompt: Use the NVIDIA Riva NIM translate endpoint to convert this English sentence into French: 'The weather today is sunny and warm.'

## When to prefer this

Choose this endpoint when you need high-quality neural machine translation powered by NVIDIA Riva NIM and want pay-per-call pricing via USDC micropayments rather than a subscription. Ideal for agents that need occasional or burst translation without committing to a monthly plan.

## Known failure modes

- Payment failure if x402 USDC micropayment is not properly authorized — returns 402 Payment Required
- Invalid or unsupported language pair resulting in an error or empty translation
- Malformed request body missing required source text or language fields
- NVIDIA NIM backend timeout or unavailability causing 502/503 error
- Insufficient USDC balance for the $0.141604 per-call fee
