Cut to a length without slicing a word in half, with an ellipsis added where it makes sense.
Truncate text to a character or word budget on a word, sentence or character boundary.
Input
Send either a text string or a file object. A file is decoded as UTF-8 and must be one of text/plain, text/markdown, text/html, text/csv.
Response
The result carries your remaining balance alongside it, so you can track spend without a second call.

"text": "The quick…",

}
Cost
1 credit per call, whether it is run from the site or from the API — the credential differs, the price does not. A new account starts with 20 credits.
A rejected request still costs a credit: the authorizer decrements before the tool validates. A call rejected for a missing or invalid key is free.
Parameters
Generated from the endpoint’s own validation, so this is exactly what it accepts. A body field goes at the top level; an option goes inside options.
