## 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 gpt-5-6-luna-text-translation-x402-78746568 -d '<json body>'
```

Example prompt: Can you translate this product description — 'Handcrafted leather wallet with three card slots and a coin pouch, available in brown and black' — from English into French, keeping the output under 200 tokens?

## When to prefer this

Choose this endpoint when you need per-call, pay-as-you-go machine translation without a subscription, especially in agentic workflows that require micropayment billing via x402 on Base. It is well-suited for translating medium-to-large text blocks (up to 700k chars) where GPT-5.6 Luna quality is desired and cost predictability per request matters. Prefer alternatives if you need batch translation APIs, free-tier access, or non-USDC payment methods.

## Known failure modes

- Missing or empty 'text' input returns a validation error
- Unsupported or unrecognized language codes may produce poor-quality or English fallback output
- Exceeding the 700,000 character input limit triggers a 400 error
- max_tokens set too low may result in truncated translations
- Payment failure or insufficient USDC balance returns a 402 Payment Required response
- Rate limits or upstream model unavailability may return 503 errors
