## How to call it through Zero

```

Example prompt: Find me underpriced trading card deals right now — specifically look at Pokémon Base Set cards and show me any listings on eBay where the asking price is significantly below recent sold prices so I can flip them.

## When to prefer this

Use this endpoint when an agent needs to identify specific underpriced trading card listings with quantified arbitrage potential based on real eBay sold-vs-listed gap analysis. Prefer this over general card pricing endpoints when the goal is actionable buy opportunities rather than just market value lookup.

## Known failure modes

- Card or set not found — no listings or sold history available
- Insufficient sales volume to compute a reliable gap — returns low-confidence or empty results
- eBay data temporarily unavailable — upstream fetch failure
- Invalid card query parameter — 400 error
- Payment not processed — 402 payment required before data is returned
