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-tool-gpt-5-5-x402-gateway-a8b6740e
```

Example prompt: Can you get me the word count, line count, byte size, and estimated reading time for this article text: 'Artificial intelligence has rapidly transformed industries across the globe, from healthcare to finance...'?

## When to prefer this

Use this endpoint when you need lightweight, deterministic text statistics (word count, lines, bytes, reading time) without spinning up a full NLP pipeline, and want per-call micropayment billing with no subscription. Ideal for agents that need quick content length metrics as part of a larger workflow.

## Known failure modes

- Missing 'text' query parameter returns an error
- Text exceeding 20,000 characters is rejected
- Payment failure via x402/USDC results in 402 response
- Empty text string (minLength:1 violated) returns validation error
- Network or gateway timeout for large inputs

## How this service works

Analyze text length, words, lines, sentences, paragraphs, bytes, and estimated reading time without calling an upstream model. GET variant for agents, crawlers, and wallets that prefer query parameters over a JSON body. Pay up to $0.0001 per request with x402 USDC on Base.

## Output

Returns a JSON object with ok status, tool name ('textStats'), and a summary including word count, line count, byte count, and estimated reading time for the submitted text.

## Example request

```json
{
 "input": {
  "type": "http",
  "method": "GET",
  "queryParams": {
   "text": "Artificial intelligence has rapidly transformed industries across the globe, from healthcare to finance. Machine learning algorithms now power recommendation systems, diagnostic tools, and autonomous vehicles. As AI continues to evolve, organizations must consider both the opportunities and challenges it presents."
  }
