## 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 x402-micro-pay-ai-detector-6783a47a -d '<json body>'
```

Example prompt: Can you check whether this essay is AI-generated or written by a human? Here's the text: 'The rising tide of automation has fundamentally reshaped how we think about labor and creativity...'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call AI content detection service without committing to a subscription, especially in agent workflows that need programmable micro-payments via USDC/x402 rails. Ideal for low-volume spot checks or agentic pipelines where cost-per-call billing is preferable to monthly plans.

## Known failure modes

- Missing or malformed `input` object returns a validation error
- Insufficient USDC balance or failed x402 payment results in 402 Payment Required
- Empty or missing text body may return a parsing error
- Network timeout if content is unusually long
- Invalid HTTP method in input schema causes request rejection

## How this service works

Agent-ready microservices with x402 + Stripe rails, volume primitives, tutorials, and applet UI.

## Output

Returns a JSON object with an `ok` boolean confirming the request succeeded and a `path` field echoing the endpoint. The core detection result is expected to include an AI-generated classification and likely a confidence score or probability indicating how likely the content is machine-generated versus human-written.
