## 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 phantom-api-nft-floor-price-on-ink-network-4024fcfb -d '<json body>'
```

Example prompt: What's the current NFT floor price for the contract address 0xabc123... on the Ink network? I want to know the cheapest entry point for that collection right now.

## When to prefer this

Use this endpoint when you need fast, pay-per-call floor price lookups for NFT collections specifically on the Ink blockchain network. Prefer this over general NFT APIs when targeting Ink-native contracts, or when you want lightweight on-demand pricing without a subscription. The x402 micropayment model makes it cost-effective for low-frequency queries.

## Known failure modes

- Invalid or malformed contract address returns an error response
- Contract address does not exist on Ink network returns not-found error
- No active floor listings for the collection may return null or zero
- Network congestion or RPC failures may cause timeouts
- Payment failure via x402 protocol blocks the request before execution

## How this service works

## Output
