Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/libretranslateWhen to prefer
Choose this endpoint when you need on-demand, pay-per-call text translation via LibreTranslate without a subscription, especially in a web3 or DeFi context where x402 micropayments in USDC are preferred over API key billing. Ideal for agents that need low-volume, cost-controlled translation without managing API credentials.
Side effects
- Insufficient USDC balance causes payment failure and 402 response
- Invalid or unsupported language pair returns upstream error
- Malformed JSON body forwarded to upstream results in 400 error
- LibreTranslate upstream service unavailable returns 502/503
- Unsupported path below upstream origin returns 404
