Example use cases
Screening user-submitted comments

Email inbox spam filtering
“I have an email that just came in — can you tell me if this looks like spam: 'Dear valued customer, your account has been compromised. Send us your password immediately to restore access at support-login-verify.net.'?”
Screening contact form submissions
“Someone just submitted our website contact form — check if this is spam before I reply: 'Hi! We can get you 10,000 Instagram followers for just $5. DM us on WhatsApp +1-800-555-1234 to get started today!'”
Technical details
Endpoint
POSThttps://api.fastapi.online/spam-detectWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call spam classifier with no signup required, especially for one-off checks or low-volume workflows. At $0.001 per call it is cost-effective for moderate volumes. Prefer it over heavier NLP pipelines when you just need a binary spam/not-spam classification on short text up to 8000 characters.
Side effects
- Empty or missing text field returns validation error
- Text exceeding 8000 character limit is rejected
- Network timeout if the self-hosted model is under load
- Payment failure if insufficient USDC balance for the $0.001 per call fee
- Ambiguous or borderline content may produce low-confidence results
