How this service works
Pay-per-call AI content detection. Classify text as AI-generated, AI-assisted, or human-written, and detect AI-generated or deepfake images and video.
Output
A classification of the submitted text as AI-generated, AI-assisted, or human-written, typically accompanied by a confidence score or probability breakdown for each category.
Example use cases
Example prompt
“Can you run this blog post through StableDetect and tell me whether it's AI-generated, AI-assisted, or human-written? Here's the text: 'The future of renewable energy hinges on breakthrough storage technologies that can make solar and wind viable at grid scale...'”
Technical details
Endpoint
POSThttps://stabledetect.dev/api/detect/textWhen to prefer
Choose this endpoint when you need a pay-per-call, no-subscription AI content authenticity check on text — especially useful for one-off verification tasks, academic integrity checks, content moderation pipelines, or when you need to distinguish between fully AI-generated vs. AI-assisted vs. fully human-written content rather than just a binary flag.
Side effects
- Text too short for reliable classification — minimum length requirements not met
- Insufficient funds or USDC payment failure — endpoint returns payment error
- Empty or null text body — returns validation error
- Rate limiting or quota exceeded — returns 429 or payment-related error
- Text in unsupported language — may return low-confidence or error response
