Explore and consume

Point your browser to http://127.0.0.1:8001/text/?q=test&to_lang=zh

Or in command line:

python -c "import httpx; print(httpx.get('http://127.0.0.1:8001/text/?to_lang=zh&q=test 1\ntest 2').json())"
# output: {'q': 'test 1\ntest 2', 'from_lang': None, 'to_lang': 'zh', 'trtext': '测试 1\n测试 2', 'translation': '测试 1\n测试 2'}

Or in python code (pip install requests first)

import requests

# get
url = "http://127.0.0.1:8001/text/?q=test me&to_lang=zh"
print(requests.get(url).json())
# {'q': 'test me', 'from_lang': None, 'to_lang':
# 'zh', 'trtext': '考我', 'translation': '考我'}

'translation' is there for OmegaT plugin. Refer to the OmegaT Fake MT plugin setup part in https://github.com/ffreemt/deepl-fastapi

# post
text = "test me \n and him"
data = {"text": text, "to_lang": "zh"}
resp = requests.post("http://127.0.0.1:8001/text", json=data)
print(resp.json())
# {'q': {'text': 'test me \n and him', 'from_lang': None,
# 'to_lang': 'zh', 'description': None}, 'result': '考验我 \n  我和他'}

NB

• Text longer than 5000 characters will be trimmed to 5000. This is what the deepl.com webpage can handle.
• The package deepl-fastapi-pw is in essence a browser from your local IP (although a proxy can be used, refer to get-pwbroser's doc for setting up). Hence if you send too many requests too frequently, your IP may be blocked by deepl.com temporarily, which of course will also disable deepl-fastapi-pw.
