# AgentTools Reading Time Calculator

> AgentTools Reading Time Calculator is a paid API for AI agents from agentstoolshub.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-12).

Estimates how long it takes to read a text given its word count and an optional reading speed in words per minute

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agenttools-reading-time-calculator-fe83bbbe
```

Example prompt: How long would it take to read a 2,400-word article at the default silent reading speed of 200 words per minute?

## When to prefer this

Use this endpoint when you need a quick, reliable reading time estimate from a word count without any text processing — ideal for agents that already know the word count and just need the duration math done correctly, especially when handling multiple reading speed modes (silent vs read-aloud).

## Known failure modes

- Missing required 'words' query parameter returns a 400 error
- Non-numeric or negative word count values may result in a validation error
- WPM value of zero or negative is invalid and will likely cause an error or division-by-zero response
- Payment not included or insufficient USDC results in a 402 Payment Required response

## How this service works

Estimate reading time from a word count at any reading speed. Defaults to 200 words per minute — the typical silent-reading speed for adults. Use this when an agent needs to how long a text takes to read, by word count.

## Output

Returns the estimated reading time for a given word count, calculated at the specified WPM (defaulting to 200 WPM for silent reading). Typically includes the time broken down into minutes and seconds or a human-readable duration.
