curl -X POST https://agentsvc.io/api/v1/try/translate -H "Content-Type: application/json" -d '{}'

JavaScript

npm i @x402/fetch @x402/evm viem

  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ text: "Hello, how are you?", target_lang: "de" }),
});
console.log(await res.json());

Python

pip install "x402[httpx]" eth_account

from eth_account import Account
from x402 import x402Client
from x402.http.clients import x402HttpxClient
from x402.mechanisms.evm import EthAccountSigner
from x402.mechanisms.evm.exact.register import register_exact_evm_client

client = x402Client()
register_exact_evm_client(client, EthAccountSigner(Account.from_key(PRIVATE_KEY)))
async with x402HttpxClient(client) as http:
    r = await http.post("https://agentsvc.io/api/v1/proxy/translate", json={"text": "Hello, how are you?", "target_lang": "de"})
    await r.aread()
    print(r.json())

Input and output

• text: up to 1000 characters per call.
• target_lang: en, de, fr, es, it, pt, nl, pl, sv, cs, el, ru, uk, tr, ar, hi, id, vi, zh, ja or ko.
• source_lang: optional, detected if left out. Pairs without a direct model go through English.

You get translated_text, the detected source_lang with its confidence, and truncated if the text was longer than 1000 characters.

Longer texts

Split at paragraph or sentence ends into parts under 1000 characters, translate them one by one and join the results. Splitting in the middle of a sentence makes the translation worse.

Paying

No account and no API key. Three ways to pay, all only for calls that succeed:

• Wallet (x402): a separate wallet with a few dollars of USDC on Base, Solana, Polygon or Arbitrum. The x402 client pays the price from the 402 answer and retries; you pay no gas.
• Credit token: buy one at /credits ($5 to $100, USDC on Base, +10% bonus) and send it as Authorization: Bearer. Good for a script that runs through a long list.
• Zero: if your agent already uses the Zero CLI, it pays the 402 for you: zero fetch https://agentsvc.io/api/v1/proxy/translate -d '{"text":"Hello, how are you?","target_lang":"de"}'
