## How to call it through Zero

```sh
zero fetch --capability gadgethumans-compare-api-e0ed8204
```

Example prompt: Can you compare these items for me using GadgetHumans: iPhone 15, Samsung Galaxy S24, and Google Pixel 8 — I want to see how they stack up against each other?

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.002 USDC) programmatic comparison of multiple items without needing to set up your own comparison logic. It is best suited for general-purpose item comparison tasks where the items can be expressed as a string. Prefer this over building custom comparison logic when you need a lightweight, no-API-key-required solution for comparing products, crypto assets, health topics, or other entities covered by the GadgetHumans tool suite.

## Known failure modes

- Missing or empty items parameter returns an error
- Malformed items string may produce unexpected results
- Payment failure (x402) if USDC balance is insufficient
- Service unavailable if GadgetHumans API Hub is down
- Ambiguous item names may result in incomplete comparisons
