{"name":"duplicate-ticket-detect","description":"Checks a new support ticket against a batch of existing ones and ranks which are likely the same issue, so you can merge or link duplicates before they get worked twice. Send the new ticket plus up to 500 candidate tickets ({id?, text}) and get back matches sorted by lexical similarity score, each with the candidate index, id, score, and a text snippet, a word-shingle Jaccard score. Built for duplicate ticket detection, similar tickets, and support dedupe workflows; redact customer PII from ticket text upstream before sending it. Use it as a duplicate ticket detection API, similar-ticket finder, support dedupe tool, or ticket matching endpoint ahead of manual triage.","price":"$0.008","method":"POST","input_schema":{"properties":{"ticket":{"type":"string","description":"The new ticket text to check for duplicates.
