🔒 Data Security & Direct API Access

Your translation requests are processed directly by Google Cloud Translation servers. We do not store, log, or analyze your translation content. All traffic is encrypted via TLS 1.3.

For clients requiring data to never pass through any intermediary, we provision dedicated Google Cloud Translation API keys. Purchase any credit pack, then email [email protected] to arrange direct API access.

How x402 Works

1
Agent sends HTTP request to x402 endpoint
2
Server returns HTTP 402 with payment requirements
3
Agent pays via USDC on Base network
4
Request retried with payment proof → data returned
# Example: AI Agent calling x402 endpoint # Step 1: Initial request → 402 Payment Required curl -X POST https://x402.api.socketsio.com/v1/translate \ -H "Content-Type: application/json" \ -d '{"text": "Hello world", "target_lang": "zh"}' # → HTTP 402 {"price": "0.001", "currency": "USDC", "network": "base", ...} # Step 2: Agent pays on-chain, retries with X-PAYMENT header curl -X POST https://x402.api.socketsio.com/v1/translate \ -H "X-PAYMENT: <signed-payment-proof>" \ -d '{"text": "Hello world", "target_lang": "zh"}' # → HTTP 200 {"translated_text": "你好世界", "detected_lang": "en"}

Frequently Asked Questions

A Credit Pack is a one-time purchase of translation credits. Each character in the text you translate uses one credit. For example, translating "Hello World" (11 characters) uses 11 credits. Credits never expire — use them at your own pace, no monthly pressure.
After payment, your credits are added to your existing account instantly. Use your existing API key — the credits are automatically available. New users: sign up first, then purchase. Add your key to requests as the X-API-Key header. See our API Docs for full examples.
No. Credits never expire. Once you purchase a pack, the credits are added to your account balance and remain there until you use them. There are no monthly minimums, no expiry dates, no "use it or lose it" pressure.
SocketsIO API keys give you access to our Google Cloud-powered translation gateway — you get 500K free trial credits on signup plus any packs you purchase. 90% cheaper than Google's direct pricing.

Dedicated Google Cloud API keys are official Google keys we provision for enterprise clients who need data to never pass through any intermediary. Available after purchasing any credit pack — contact [email protected].
Yes! You can purchase multiple packs at any time. Credits are cumulative — buying a Starter pack and a Growth pack gives you 12M credits total. All credits are pooled in your account and never expire.
We accept all major credit/debit cards and PayPal via our secure PayPal checkout. Your payment is processed by PayPal — we never store your card details.
We offer refunds within 7 days of purchase if you haven't used any characters from the pack. Contact us at contact page with your order ID and we'll process the refund promptly.
Translation API keys are delivered instantly after payment confirmation. Maps API keys are typically delivered within 24 hours as we need to configure the proper GCP project settings and quota limits for your account.
x402 is an HTTP-native payment protocol. Instead of managing API keys, your AI agent pays per request using USDC on the Base blockchain. The flow is: agent sends request → server returns HTTP 402 with price → agent pays on-chain → request is fulfilled. No signup, no monthly fees, no key management. Ideal for autonomous AI agents that need to call APIs without human intervention.
x402 works with any HTTP client. Native support is available in Coinbase AgentKit, and it's compatible with Claude Computer Use, LangChain, AutoGPT, and custom agent frameworks. You need a Base network wallet with USDC to pay for requests. The endpoint is x402.api.socketsio.com.
