## 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`):

## When to prefer this

Use this endpoint when you specifically need NFT floor price data on the Avalanche (AVAX) network and want a pay-per-call model without a subscription. It covers Avalanche natively and is cheaper for low-frequency lookups than maintaining a full indexer subscription.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address exists but is not an NFT collection returns no floor data
- Collection has no active listings so floor price is unavailable
- Avalanche network congestion may cause delayed or stale data
- Rate limiting or payment failure ($0.01 USDC via x402) blocks the request

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns the current floor price of the specified NFT collection on Avalanche, typically expressed as a numeric value in the network's native currency (AVAX) or a stablecoin, along with any relevant collection metadata available from on-chain data.
