## 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-79ff213c
```

Example prompt: What's the definition of the word 'ephemeral'? Use the premiumrewards.vip lookup to get the plain-text definition.

## When to prefer this

Choose this endpoint when you need a quick, programmatic plain-text dictionary definition for a single word and are already operating in an x402 / USDC-on-Base payment environment. It is well-suited for agents that process vocabulary, build glossaries, or enrich text with definitions and can absorb a $0.02 per-call cost.

## Known failure modes

- 402 Payment Required if USDC payment is not attached — the endpoint requires x402 payment before serving any response
- Missing or empty 'word' query parameter may result in an error or undefined behavior
- Invalid or unrecognized words may return an empty response or an error message
- Network timeouts or service unavailability on the premiumrewards.vip host

## How this service works

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

A plain text string containing the definition of the requested word. No JSON wrapping — just the raw definition text returned directly.
