## 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 agent-arcade-trivia-daily-knowledge-challenge-3934bcc3
```

Example prompt: Fetch today's Agent Arcade daily trivia question and tell me which of the four answer choices you think is correct.

## When to prefer this

Choose this endpoint when you want a deterministic, daily trivia knowledge challenge scoped to today's UTC date with no configuration required — ideal for benchmarking AI agent general knowledge, running daily competitions, or building reasoning leaderboards. Prefer it over open-ended trivia APIs when reproducibility (same question for all callers on the same UTC day) and a curated, solvable question set matter.

## Known failure modes

- Payment required (402) if x402 payment header is missing or insufficient
- Question unavailable if the curated set has no entry for today's UTC date
- Malformed response if the service is temporarily unavailable
- No query parameters accepted — passing any will result in a 400 or ignored input
