## How to call it through Zero

Example prompt: What's the current floor price for the NFT collection at contract address 0xAbC123... on the Celo network?

## When to prefer this

Choose this endpoint when you specifically need NFT floor price data on the Celo blockchain and want a pay-per-call model without subscription overhead. It is well-suited for agents that need lightweight, on-demand NFT pricing lookups on Celo rather than broad multi-chain NFT analytics. Prefer this over general blockchain explorers when you need structured, machine-readable floor price output rather than raw transaction data.

## Known failure modes

- Invalid or malformed contract address returns a 400 or error response
- Contract address does not correspond to an NFT collection on Celo — returns not found or null data
- No active listings exist for the collection, making floor price unavailable
- Network congestion or RPC node issues may cause timeouts
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Celo network downtime or reorganization may return stale or inconsistent data

## How this service works
