A simple Python wrapper for Bing, DeepL, and Google Translate.

This library allows you to use these translation services without official API keys by utilizing their web interfaces/public endpoints.

Note: Since this relies on scraping or undocumented endpoints, stability depends on the providers not changing their frontend or blocking requests. DeepL is particularly strict with rate limiting.

pip install mintrans

Basic usage for all three supported engines.

from mintrans import BingTranslator, DeepLTranslator, GoogleTranslator
from mintrans import RateLimitException

text = 'Hello World'
source = 'en'
target = 'fr'

# 1. Bing
bing = BingTranslator()
print("Bing:", bing.translate(text, source, target))

# 2. Google
google = GoogleTranslator()
print("Google:", google.translate(text, source, target))

# 3. DeepL
# DeepL is more prone to IP blocks and rate limits.
deepl = DeepLTranslator()

try:
    result = deepl.translate(text, source, target)
    print("DeepL:", result)
except RateLimitException:
    print("DeepL rate limit reached.")
except Exception as e:
    print(f"DeepL error: {e}")

• Bing: Generally stable.
• Google: Standard web translation.
• DeepL: High quality, but very low tolerance for repeated requests from the same IP.

• Language codes follow standard ISO 639-1 format (e.g., en, fr, es, ja).
• Not recommended for high-volume production use due to the lack of official API guarantees.
