## When to prefer this

Use this endpoint when you need a quick, no-signup dictionary definition lookup powered by Wiktionary data and are operating in an x402 micropayment environment where paying $0.002 USDC per call is preferable to managing API keys or subscriptions. Ideal for AI agents that need on-demand lexical data without any authentication overhead.

## Known failure modes

- Word not found in Wiktionary — returns error or empty definition
- Invalid or missing schema/word parameter — malformed request
- Payment failure via x402 — call not executed if USDC micropayment not completed
- Rate limiting or service unavailability on the upstream Wiktionary source

## How this service works
