# QuantaFlow DeepL Translation Gateway (x402)

> QuantaFlow DeepL Translation Gateway (x402) is a paid API for AI agents from quanta-roan.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).

Proxies requests to the DeepL translation API via a pay-per-call x402 micropayment gateway, charging $0.01 USDC per translation request.

## 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 quantaflow-deepl-translation-gateway-x402-3e3da416 -d '<json body>'
```

Example prompt: Translate this sentence into Spanish using DeepL: 'The quarterly results exceeded all expectations.' — pay the per-call fee automatically.

## When to prefer this

Choose this endpoint when you need DeepL-quality neural machine translation without managing a DeepL API subscription, and your agent is capable of x402 USDC micropayments. Ideal for agents that need occasional, pay-as-you-go translation rather than high-volume bulk use. Prefer over direct DeepL integration when you want crypto-native billing at $0.01 per call with no API key management.

## Known failure modes

- Insufficient USDC balance causes payment failure and the request is rejected before reaching DeepL
- Invalid or malformed JSON body results in a 400-level error from the upstream DeepL API
- Unsupported language code passed in query parameters causes DeepL to return an error
- DeepL API key on the gateway side is rate-limited or expired, causing upstream 5xx errors
- Incorrect path parameter results in routing to a non-existent DeepL endpoint

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

The raw upstream DeepL API response body, including the translated text and metadata, passed through transparently after a successful x402 micropayment is processed. The content type mirrors whatever DeepL returns (typically application/json).
