# Swift Bot Labs Toolbox – Text Stats

> Swift Bot Labs Toolbox – Text Stats is a paid API for AI agents from x402-toolbox.swiftbotlab.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-31).

Analyzes a text string and returns word count, sentence count, character count, top keywords, Flesch Reading Ease score, and estimated reading time.

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 swift-bot-labs-toolbox-text-stats-48793520 -d '<json body>'
```

Example prompt: Can you analyze this paragraph for me — count the words, sentences, and characters, give me the Flesch Reading Ease score, estimate how long it'll take to read, and pull out the top 5 keywords: 'The quick brown fox jumps over the lazy dog. Pack my box with five dozen liquor jugs.'

## When to prefer this

Use this endpoint when you need fast, deterministic text statistics — word/sentence/character counts, readability scoring (Flesch), reading time, and keyword frequency — without needing an LLM or NLP cloud service. Ideal for lightweight content auditing, SEO keyword checks, or readability gates in automated workflows. Pay-per-call with no account setup makes it suitable for low-volume or one-off agent tasks.

## Known failure modes

- Text exceeds 1,048,576 character limit — returns validation error
- top parameter exceeds 100 — returns validation error
- Empty or missing text field — may return zero counts or error
- Payment failure via x402 — 402 response if USDC payment is not completed

## How this service works

62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.

## Output

Returns a JSON object with ok:true, the tool name, and a result object containing: words (integer), sentences (integer), characters (integer), topKeywords (array of {word, count} objects up to the requested top-N), fleschReadingEase (float, 0–100 scale), and readingTimeSeconds (integer).
