How this service works
Process the files and content an agent gives you. Nothing else. A pay-per-call kit for AI agents in USDC on Base (x402/MPP): pdf, web-read, extract, summarize, and the free detect-language entry point - see GET /capabilities. Plus two tools outside the kit: translate and jobs.
Output
A JSON object containing the translated text, the target language code, the model used (agentindex-translate-1), and the detected source language code (useful when auto-detection was requested).
Example use cases
Localizing multilingual e-commerce listings
“I have 150 product descriptions in French that I need translated into English for our US store — please keep all the markdown bold and italic formatting unchanged.”
Auto-detecting and translating user feedback
“I've got a mix of customer reviews in unknown languages — can you detect each one's language and translate them all into English so I can read them?”
Translating templated UI strings for an app
“Translate these 80 UI strings from English to Japanese, but make sure the {username} and {{count}} placeholders stay exactly as they are and don't get translated.”
Technical details
Endpoint
POSThttps://x402.agentindex.world/translateWhen to prefer
Choose this endpoint when you need pay-per-call translation without a subscription, especially for batch workloads of up to 200 segments in a single call, or when localizing structured content like markdown, HTML, or template strings where format preservation is critical. It is ideal for AI agent pipelines that need on-demand translation billed in USDC micro-payments.
Side effects
- Unsupported or invalid target_lang ISO 639-1 code returns an error
- Array exceeding 200 items is rejected
- Payment failure via x402 protocol results in 402 response before translation occurs
- Ambiguous or very short text may produce incorrect language auto-detection
- Heavily formatted content may have placeholder corruption if preserve_format is not set
