## 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 fanpulse-compare-11d5a06c
```

Example prompt: Can you settle the debate once and for all — who wins, Gandalf or Dumbledore? Give me a definitive verdict with reasoning.

## When to prefer this

Use this endpoint when a user wants a decisive, opinionated verdict settling a pop-culture or fan debate between two specific entities — characters, franchises, artists, or bands. Prefer this over generic search or lore endpoints when the goal is a comparison outcome rather than factual information about a single entity. Ideal for fan debate resolution, trivia contexts, or entertainment recommendation flows.

## Known failure modes

- Unrecognized or obscure entities may return low-confidence or inconclusive results
- Comparing entities from wildly different domains may produce less coherent verdicts
- Payment failure via x402 protocol returns 402 status before any comparison is made
- Missing or malformed entity parameters return a 400-level error
- Rate limiting may occur with rapid successive comparisons

## How this service works

Decisive cross-franchise and cross-artist comparisons for fan and entertainment agents. Settles debates like Gandalf vs Dumbledore or Beatles vs Rolling Stones with a definitive call.

## Output

A structured response containing a definitive winner or verdict, detailed reasoning across multiple comparison dimensions (power, lore impact, cultural relevance, etc.), and a fan-debate analysis explaining why this call is justified.
