## 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 premiumrewards-vip-word-definition-lookup-db08e857
```

Example prompt: Can you look up the definition of the word 'ephemeral' for me?

## When to prefer this

Prefer this endpoint when you need a quick, programmatic plain-text dictionary definition for a single word and are operating in a micropayment-enabled (x402/USDC on Base) environment. It is suitable for agents that need to define terms on the fly without scraping external websites or calling a large language model.

## Known failure modes

- 402 Payment Required — returned when the request is made without valid USDC payment on Base
- Missing 'word' query parameter — request fails if the required word field is not provided
- Unknown or unrecognized word — may return an empty or error response if the word is not in the backing dictionary
- Network timeout — the service may be temporarily unreachable

## How this service works

Four paid HTTP lookups. USDC on Base. Unpaid GET returns 402.

## Output

A plain-text string containing the definition of the queried word, returned directly in the response body.
