Is a statement true of the text?
Answers one or more statements with a yes/no and the probability. Add when_true / when_false to sharpen the boundary.
Send text for one result, texts for a batch wrapped as { results: [...] }, or image (one image, at most 5 MB decoded, optionally with text; never with texts). The response carries x-input-chars (input characters) and x-input-tokens (input tokens billed for this call) headers. Each item of texts (and each of statements or questions) counts as one request against the requests-per-minute limit.
