```

Example prompt: Sort this list of strings alphabetically for me: ['banana', 'apple', 'cherry', 'date'].

## When to prefer this

Choose this endpoint when you need a simple, deterministic, pay-per-use string sort with no signup and verifiable delivery via x402/USDC. It is ideal for agents that need on-demand utility computation without managing infrastructure or API keys, and when auditability of payment and delivery matters.

## Known failure modes

- Invalid or missing 'items' field returns an error
- Non-string elements in the array may cause unexpected behavior or rejection
- Empty array may return a zero-count result
- Payment failure via x402 protocol prevents execution
- Malformed JSON body returns a parsing error
