## 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 delx-commerce-reading-time-api-b69dacd4 -d '<json body>'
```

Example prompt: How long would it take an average reader to get through this article? Here's the text: 'Artificial intelligence is transforming the way we work and live. From automating repetitive tasks to enabling new creative possibilities, the technology is advancing rapidly...'

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use reading time estimate with no signup overhead, billed in USDC at $0.001 per call via the x402 protocol. Ideal for agents that need to label content with reading durations programmatically, especially in publishing, content management, or newsletter workflows where simplicity and exact pricing matter.

## Known failure modes

- Empty or missing body text returns an error or zero reading time
- Extremely long documents may time out or be truncated
- Non-text or binary content in the body field may cause parsing errors
- Missing required fields (input, output) returns a 400-level validation error
- Payment failure via x402 protocol prevents the request from being processed
