## 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 gamepulse-trading-card-portfolio-valuation-83b4aced
```

Example prompt: Can you tell me what my trading card portfolio is currently worth? I have 50 Pokemon cards including a first edition Charizard, 30 MTG Dual Lands, and a 2018 Topps Mike Trout rookie card — all in near-mint condition.

## When to prefer this

Use this endpoint when an agent needs to value an entire collection of trading cards at once rather than a single card — ideal for card investors wanting portfolio net worth, collectors cataloging holdings, or anyone needing a holistic view across multiple TCG formats (Pokemon, MTG, sports cards). Prefer this over the single-card pricing endpoint when the user has multiple cards and wants an aggregated total.

## Known failure modes

- Unknown or unsupported card name returns partial valuation with missing entries
- Card set or edition not specified leads to averaged or ambiguous pricing
- Unsupported TCG format returns error or empty results
- Stale market data may cause valuation lag during high-volatility periods
- Payment failure (x402) blocks request before valuation is returned
- Malformed card list input returns 400 validation error
