## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tollmint-ai-content-score-3d1e8837 -d '<json body>'
```

Example prompt: Can you check this article draft for AI-generated content and give me a score with a sentence-by-sentence breakdown? Here's the text: 'The rapid advancement of artificial intelligence has transformed industries worldwide, enabling unprecedented automation and decision-making capabilities.'

## When to prefer this

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.

## Known failure modes

- Text too short (below minLength of 1) — likely returns a 400 validation error
- Text exceeding 50,000 characters — request rejected with length 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

## 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.
