## 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`):

Example prompt: What's the current floor price for the Base NFT collection at contract address 0xd4307e0acd12cf46fd6cf93bc264f5d5d1598792?

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.01) floor price lookup for a specific Base NFT collection contract and only need the minimum listing price from OpenSea or LooksRare. Prefer this over broader NFT analytics APIs when you just need the floor figure for Base-native collections without full market depth or historical data.

## Known failure modes

- Collection contract address not listed on any supported marketplace — returns empty or null floor price
- Invalid or non-Base contract address — returns error or no data
- Collection not indexed by Alchemy — no coverage
- Payment not completed (402 returned) — agent must pay $0.01 USDC on Base to 0x973a31858f4d2125f48c880542da11a2796f12d6 and retry
- Network or relay downtime — 5xx error from relai.fi
