## 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-floor-price-multi-chain-lookup-9b1c7215
```

Example prompt: What's the current floor price for Bored Ape Yacht Club on Ethereum — give me the floor in ETH and USD and the 24-hour change?

## When to prefer this

Use this endpoint when you need a fast, unified floor price lookup across multiple blockchains without managing separate CoinGecko and Magic Eden API keys. It's ideal for agents that need to compare NFT floors across EVM chains and Solana/Bitcoin in a single call, or when you want USD-normalized pricing alongside native currency floors without additional conversion logic.

## Known failure modes

- Collection not found — invalid slug, symbol, or contract address returns an error or empty result
- Unsupported chain — passing a chain not in the supported enum returns a validation error
- Missing required parameters — omitting both slug and contract for EVM collections results in an error
- Data lag — floor data may be slightly delayed depending on the upstream provider refresh rate
- Magic Eden collection symbol mismatch — Solana/Bitcoin collections require the exact marketplace symbol, not a display name

## How this service works

Multi-chain NFT collection floor price in one call: floor in native currency AND USD, 24h floor change percent, market cap and the resolved source. EVM via CoinGecko (pass chain+contract or a CoinGecko slug), Solana + Bitcoin-Ordinals via Magic Eden (pass chain plus the marketplace symbol as slug). Keyless, attributed.

## Output

Returns a JSON object with: floor price in the collection's native currency, floor price in USD, 24-hour floor price change percentage, market cap, and the resolved data source (CoinGecko for EVM, Magic Eden for Solana/Bitcoin).
