How this service works
One remote endpoint gives your agent live data from Twitter, Reddit, the open web, GitHub and more. No API keys, no scraping stack - just connect the URL and go.
Output
Returns a JSON object with a prediction label (e.g. 'AI-Generated', 'Human', 'Mixed'), a confidence level (Low/Medium/High), fraction_ai and fraction_human as decimals, a natural-language prediction summary, word count, tier used, cost in USD, and a segments array breaking down the text into labeled spans with per-segment AI/human scores and word start/end indices.
Example use cases
Academic submission integrity check
“I need to check if this student essay was AI-generated. Run it through the premium AI detector so it catches humanized text too: 'The French Revolution was a period of radical political and societal change in France that began with the Estates General of 1789 and ended with the formation of the French Consulate in November 1799...'”
Content farm audit for a publisher
“We received this guest blog post and I'm not sure it's human-written. Can you run it through the standard AI detector and tell me what fraction is AI vs human, and which segments are flagged? Here's the text: 'Remote work has fundamentally altered the modern employment landscape, with millions of professionals now operating outside traditional office environments on a permanent basis...'”
Detect humanized AI output in job applications
“This cover letter feels like it might be AI-written and then run through a paraphraser. Use the premium tier to check — I want to know if it's flagged as humanized AI: 'Throughout my career I have cultivated a genuine passion for connecting talented individuals with meaningful opportunities, and I believe this role represents an exceptional chance to apply my skills...'”
Technical details
Endpoint
POSThttps://surf.cascade.fyi/api/v1/detect/aiWhen to prefer
Choose this endpoint when you need segment-level AI detection with confidence scores and humanizer detection in a single pay-per-call model, with no API key setup. Prefer the premium tier when content may have been run through a paraphrasing/humanizer tool or when high-accuracy verdicts are critical. Use standard tier for high-volume, cost-sensitive routine checks.
Side effects
- Text shorter than 50 characters returns a validation error
- Very short texts may return low-confidence verdicts even if valid
- Text exceeding 40,000 chars (standard) or 20,000 chars (premium) is rejected
- Payment failure via x402 results in 402 response blocking the call
- Highly evasive or humanized text may evade standard tier detection — use premium for robustness
- Non-English or code-heavy text may reduce detection accuracy
