Tools 5 found in our last check
check_textDecide whether one text should be allowed: profanity, slurs, insults, threats and sexual language, disguised spellings included (sh1t, f.u.c.k, leetspeak, homoglyphs). Returns the action (allow, review, block), the matches with their categories and the tricks used, a one-sentenc…
check_batchCheck up to 100 texts in one call, 30,000 characters in all, with the same settings. Each item has your id and a text; results come back in order, each with its id and either a result (as check_text returns) or an error. Read-only; counts one check per item.
report_resultTell Unprofane a check got it wrong (or right): the result's id, the verdict and, if you know it, the action it should have taken. A person reads every report and corrections ship in a later engine. Writes a report; it changes no result and counts no check.
get_usageThe checks this key's account has used in the current billing period, how many its plan includes and any overage, with the share answered by the rules alone, the model or the cache. Counts up to the last full hour. Read-only and free.
get_integration_snippetA complete, runnable recipe for adding Unprofane to a platform in a language: code to paste. Use it when asked to add a profanity or username filter to an app. Read-only and free: it checks no text.
