# Text Statistics Analyzer

> Text Statistics Analyzer is a paid API for AI agents from x402-gateway-production-1f21.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).

Computes statistical metrics (word count, character count, sentence count, readability scores, etc.) from a submitted text string

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 text-statistics-analyzer-3cd9c1ef -d '<json body>'
```

Example prompt: Can you analyze the statistics of this text — word count, character count, sentence count, and readability — for the following paragraph: 'The quick brown fox jumps over the lazy dog. It was a bright and sunny day in the valley.'?

## When to prefer this

Choose this endpoint when you need fast, deterministic text metrics (word count, character count, sentence count, readability) for a single text payload up to 250,000 characters, especially within machine-payable x402 micro-payment workflows where per-call pricing at $0.001 USDC is acceptable. Prefer this over heavyweight NLP APIs when you only need statistical measures rather than semantic understanding or entity extraction.

## Known failure modes

- Text exceeds 250,000 character limit — request rejected with validation error
- Empty or missing 'text' field in body — returns schema validation error
- Payment not included or insufficient — x402 payment required error returned
- Malformed JSON body — returns parse error
- Network timeout on Railway deployment — transient 5xx error

## How this service works

Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.

## Output

Returns a JSON object with computed text statistics such as word count, character count, sentence count, paragraph count, average word length, average sentence length, and readability metrics (e.g. Flesch-Kincaid score) derived from the submitted text.
