## 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`):

## When to prefer this

Use this endpoint when a user wants to know which credit card to use to maximize rewards for a specific type of purchase or spending category. Prefer this over generic financial advice APIs when the goal is concrete card-level reward optimization rather than card comparison for signup bonuses or interest rates.

## Known failure modes

- Unknown or unsupported spending category returns empty results or generic fallback
- Ambiguous category (e.g. 'online' without merchant type) may return suboptimal match
- Card data may be slightly stale if issuer changed reward structure recently
- Payment failure (402) if USDC balance is insufficient
- Rate limiting if too many requests in a short window
