## 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 nft-collection-floor-price-lookup-f317df15
```

Example prompt: What's the current floor price for Bored Ape Yacht Club on Ethereum? Use the CoinGecko slug bored-ape-yacht-club.

## When to prefer this

Use this endpoint when you need real-time NFT floor prices across EVM chains (Ethereum, Base, Polygon, Arbitrum, Optimism, Avalanche, BSC) via CoinGecko IDs or Solana/Bitcoin collections via Magic Eden symbols. Prefer it over alternatives when you need a single unified API that covers both EVM and non-EVM NFT ecosystems and accepts micropayment via x402/USDC.

## Known failure modes

- Invalid or unknown collection slug returns empty or error result
- Unsupported chain/slug combination causes failure
- Missing required slug or contract address returns validation error
- Collection not indexed by CoinGecko or Magic Eden returns no data
- Rate limiting or payment verification failure blocks the response

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output
