How this service works
Invoice-to-JSON, on-chain tools (transaction explainer + payment check, wallet profile, contract ABI, ERC-20 token risk), company contacts and web-to-RAG for AI agents. Pay per call with x402 (USDC on Base). No signup, no API key.
Output
A JSON object containing the translated text string, the detected or specified source language code, and the target language code (e.g. {"to": "de", "from": "auto", "translation": "Danke für das Gespräch heute..."}).
Example use cases
Customer support multilingual reply
“Translate this support response into French so I can send it to a French-speaking customer: 'We have received your refund request and will process it within 5 business days.'”
Product description localization
“I need this product description translated into Japanese: 'Our organic coffee beans are sourced directly from small farms in Colombia and roasted fresh weekly.'”
User-generated content moderation
“Translate this user review into English so I can read it — it's in Arabic: 'المنتج رائع والتوصيل كان سريعاً جداً، سأشتري مرة أخرى بالتأكيد.'”
Technical details
Endpoint
GEThttps://freetier-agent-api.pages.dev/api/translate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, inexpensive ($0.005/call) text translation into one of 28 common languages with automatic source detection, especially in agent workflows where you don't know the source language in advance. Ideal for short-to-medium text (under 3,000 chars). Prefer alternatives for very large documents, specialized domains (legal/medical), or languages outside the supported 28.
Side effects
- Text exceeds 3,000 character limit — request rejected or truncated
- Unsupported target language code provided — returns error
- Malformed query parameters — missing required 'text' or 'to' fields
- Workers AI model timeout or rate limit — 5xx response
- Payment not processed (x402 protocol) — 402 response blocking the call
