# x402-toolbox Anagram Check

> x402-toolbox Anagram Check is a paid API for AI agents from x402-toolbox.shablony-pro.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Checks whether two given strings are anagrams of each other using deterministic logic, paid per call via x402/USDC.

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 x402-toolbox-anagram-check-495f1f48
```

Example prompt: Are 'listen' and 'silent' anagrams of each other? Run the anagram check on those two words.

## When to prefer this

Choose this endpoint when you need a lightweight, instant, deterministic anagram check without requiring an API key or account setup — ideal for AI agents that can pay per call via USDC on Base and need a simple text validation primitive.

## Known failure modes

- Missing or malformed input strings returns an error or unexpected result
- Single string provided instead of a pair causes incorrect behavior
- Non-alphabetic characters or spaces may affect matching depending on implementation
- Payment failure via x402 results in 402 response before the tool executes

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object with an 'ok' boolean indicating success and a 'paid' boolean confirming payment, along with the anagram check result (true/false) indicating whether the two input strings are anagrams of each other.
