Translate text API: any language to any language with detection

$0.01 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

Translate text between languages with an open LLM (gpt-oss-20b; M2M100 for less common languages): the source language is detected, the target is an ISO code such as en, sv, de, fr, es, zh or ja, and long text is split at sentence ends and checked so a cut-off translation is never charged. Use to localise messages, documents, product copy and support replies.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/ai/translate-text?text=Payment%20received%2C%20thank%20you!&to=sv"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/ai/translate-text?text=Payment%20received%2C%20thank%20you!&to=sv&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.

Example result

  "translatedText": "Betalning mottagen, tack!",
  "from": "en",

  "chars": 28,
