How this service works
Spam detection: classify text as spam or not spam with a confidence score. Powered by Jev, with an automatic Groq-hosted LLM fallback if Jev is slow or unavailable - under 4.5s guaranteed. Try GET /spam-check/sample.
Output
Returns a spam/not-spam classification label and a numeric confidence score (0–1) indicating how certain the model is. Response is guaranteed within 4.5 seconds, served by Jev with automatic Groq-hosted LLM fallback if Jev is slow or unavailable.
Example use cases
Filtering user-submitted comments
“I need you to check this comment someone just submitted on my site for spam before I publish it: 'Buy cheap followers now!! 100% real guaranteed, visit spamsite.biz' — is it spam and how confident are you?”
Email pre-screening for support inbox
“Before routing this incoming support email to my team, tell me if it's spam: 'Dear customer, your account has been compromised. Send us your login details immediately to restore access.' Give me the spam verdict and confidence.”
Spam guard for chat app messages
“A user just sent this in my chat app — classify it as spam or not spam with a confidence score: 'Act now! Limited time crypto investment returns 1000% in 24 hours. DM for details.'”
