## 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 one-engine-word-lengths-analyzer-n-32-tier-5-f2500b2a -d '<json body>'
```

Example prompt: Analyze this paragraph and return the character lengths of the first 32 words with Tier 5 diagnostics: 'The quick brown fox jumps over the lazy dog and then continued running across the wide open field toward the distant mountains where eagles soared freely above the ancient pine trees.'

## When to prefer this

Choose this endpoint when you need a deterministic, reproducible word-length extraction for exactly the first 32 words of a text, especially when Tier 5 diagnostic enrichment (aggregate statistics) is needed alongside the raw lengths array. Ideal for pipelines requiring consistent, cheap, pay-per-call text feature extraction without relying on heavyweight NLP services.

## Known failure modes

- Empty or missing text input returns an error or empty array
- Text with fewer than 32 words returns lengths only for available words
- Non-text or binary input may cause parsing errors
- Payment failure (x402) blocks the request before processing
- Malformed POST body returns a 400-level error

## How this service works

Deterministic local text analysis utility: Return lengths of first N words; parameter=32. Tier 5/10 provides progressively richer diagnostics.

## Output

Returns an array of integer character lengths corresponding to each of the first 32 words in the submitted text, accompanied by Tier 5 progressive diagnostic metadata which may include aggregate statistics such as mean, min, max, and distribution summary of the word lengths.
