How this service works
An API that quotes its own price and takes payment in the same request. Built for autonomous agents: no account, no invoice, no human in the loop.
Output
A JSON object containing an overall AI-likelihood score (probability 0–1) indicating how likely the text is AI-generated, and optionally an array of per-sentence scores if include_sentences is true, enabling granular authorship analysis.
Example use cases
Academic submission AI audit
“I need to check whether this student essay was written by AI — can you run it through an AI content scorer and show me the breakdown by sentence? Here it is: 'Photosynthesis is the process by which plants convert sunlight into chemical energy stored in glucose molecules.'”
Content farm detection for publishers
“We received this guest post pitch and I want to know if it's AI-generated before we publish it — score the whole thing and flag any sentences that look particularly non-human. Text: 'In today's fast-paced digital landscape, brands must leverage synergistic content strategies to maximize engagement metrics.'”
AI watermark check for compliance
“Before we submit this report to the regulator, can you verify it doesn't read as AI-written? Score it and include per-sentence results so we can review anything suspicious. The text is: 'Our quarterly review indicates sustained growth across all key performance indicators, with revenue increasing 12% year-over-year.'”
Technical details
Endpoint
POSThttps://api.tollmint.com/v1/content/ai-scoreWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call AI content detection score with no account setup, especially in autonomous agent pipelines that handle x402 micropayments natively. It is ideal for per-document audits where you want sentence-level granularity without a subscription commitment. Prefer alternatives with dedicated dashboards or bulk batch APIs if you are processing thousands of documents at once or need human review workflows.
Side effects
- Text too short (below minLength of 1) — likely returns a 400 validation error

- Empty or missing text field — validation error
- Payment failure or insufficient funds via x402 protocol — 402 response before scoring occurs
- Malformed JSON body — 400 bad request
- Model unavailability — 500 or timeout
