## 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 httpay-token-compare-api-9df153c9 -d '<json body>'
```

Example prompt: Compare AERO, DEGEN, and BRETT side by side — I want to see price, market cap, volume, liquidity, holder count, and any security flags for each.

## When to prefer this

Use this endpoint when you need to compare multiple tokens simultaneously rather than looking up one at a time — especially useful for Base ecosystem tokens. Prefer this over single-token lookups when doing side-by-side analysis, ranking tokens by a metric, or screening for security risk across a short list. No API key required; pay per call via USDC on Base.

## Known failure modes

- Invalid token symbol returns empty or error for that token
- Fewer than 2 or more than 5 tokens returns validation error
- Unknown contract address returns not found
- Network error or x402 payment failure returns 402 or 5xx
- Unrecognized symbols on non-Base chains may return no data
