## 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 delx-commerce-random-choice-api-7020081c -d '<json body>'
```

Example prompt: Randomly pick one option from this list for me: ['pizza', 'sushi', 'tacos', 'burgers'] — just give me one result.

## When to prefer this

Choose this endpoint when you need a verifiable, pay-per-use random selection with no signup or API key — ideal for AI agents that require transparent micropayment accountability (USDC on Base or Solana) and need to make one-off random choices programmatically without managing a subscription or rate limit.

## Known failure modes

- Empty or missing input body returns a validation error
- Malformed JSON body causes a 400 bad request
- Payment failure or insufficient USDC balance blocks the call via x402 protocol
- Input not conforming to required schema (missing 'input' or 'output' fields) returns an error
- Non-POST method returns method-not-allowed
