# QuantaFlow x402 API Gateway – Rapid Deep Translate

> QuantaFlow x402 API Gateway – Rapid Deep Translate is a paid API for AI agents from quanta-roan.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-14).

Proxies paid translation requests through an x402 micropayment gateway, forwarding the request body and path to an upstream deep-translation service and returning its response.

## 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-x402-api-gateway-rapid-deep-translate-40eee767 -d '<json body>'
```

Example prompt: Translate the following paragraph from Spanish to English using the QuantaFlow deep translate service: 'El clima de hoy es soleado y agradable para salir a caminar.'

## When to prefer this

Choose this endpoint when you need a pay-per-call translation capability gated by x402 micropayments (USDC on-chain), making it suitable for autonomous AI agents that manage their own crypto wallets and need to pay for translation without a traditional API subscription. Prefer this over conventional translation APIs when operating in a web3 or DeFi context where on-chain payment attestation is required or desired.

## Known failure modes

- Payment verification failure if x402 header is missing or malformed — returns 402 Payment Required
- Upstream translation service unavailable — passes through 5xx error from upstream
- Invalid or missing request body — upstream may return 400 Bad Request
- Unsupported language pair — upstream returns an error indicating the language is not supported
- Rate limiting by upstream service — 429 Too Many Requests passed through
- Invalid path parameter causing routing failure — 404 Not Found

## How this service works

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

## Output

The raw upstream response body from the deep translation service, passed through as-is after successful x402 payment verification. Includes the translated text and the original content type returned by the upstream provider.
