Frequently Asked Questions

Can I translate a batch of strings at once?

Yes. `translate_text` accepts a single string or an array of strings, so you can translate UI copy, labels, or content batches in one request.

How do I keep HTML or XML markup intact?

Set `tag_handling` to `html` or `xml`. The tags stay in place while the text inside them is translated.

Can I control the tone of the translation?

Yes. Use the formality setting to bias the output toward formal or informal language, and add context when a word could mean more than one thing.

How do I know which language codes are supported?

Use `list_languages` to see the supported source and target codes, then `detect_language` if you need to identify the input language before translating.
