## 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-reading-time-3fccd3f2 -d '<json body>'
```

Example prompt: How long will it take someone to read an article with 1200 words?

## When to prefer this

Use this endpoint when you need a fast, cheap, single-call reading time estimate from a known word count — ideal for content pipelines, CMS enrichment, or editorial tooling where you already have the word count and just need the computed reading time label without building the calculation yourself.

## Known failure modes

- Missing or non-numeric word count input returns a validation error
- Word count of zero or negative value may return an error or a zero-minute estimate
- Network timeout or service unavailability returns a 5xx error
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request

## How this service works

Estimate reading time from word count for $0.001 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

## Output

Returns an estimated reading time (in minutes) calculated from the provided word count, based on average adult reading speed.
