## 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 word-tools-anagram-checker-c8bf63b5
```

Example prompt: Are 'astronomer' and 'moon starer' anagrams of each other? Check ignoring spaces and show me any letter differences.

## When to prefer this

Choose this endpoint when you need a definitive, character-level anagram check between two words or phrases, especially when inputs may differ in case, spacing, punctuation, or accented characters. It is more reliable than naive client-side checks because it normalizes all those variations and provides letter-difference breakdowns, making it ideal for word games, puzzle validation, trivia verification, and creative writing assistance.

## Known failure modes

- Missing required query parameter 'a' or 'b' returns an error
- Extremely long inputs may degrade performance or return degraded:true
- Non-alphabetic inputs with only punctuation or numbers may yield unexpected results
- Payment failure or insufficient USDC balance blocks the request

## How this service works

Check whether two words or phrases are anagrams, ignoring case, spaces, punctuation and accents; shows the letter differences.

## Output

Returns a boolean isAnagram verdict, a sorted canonical letter string, letter counts for each input, objects listing letters that appear only in A or only in B, a human-readable summary, and a list of reasons explaining why the inputs are or are not anagrams.
