Sapling AI Detector API
Metered API charged per character at $0.005 per 1,000 characters for the first 10M characters (cheaper tiers above), with a one-time $5 minimum. Converted assuming about 6 characters per English word. $0.005 per 1,000 characters x ~6,000 characters per 1,000 words = $0.03 per 1K words (6 chars/word including space is an assumption).
