## 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-bnb-nft-floor-price-63fa8c51 -d '<json body>'
```

Example prompt: What's the current floor price for the NFT collection at contract address 0xABC123... on BNB Chain?

## When to prefer this

Use this endpoint when you specifically need NFT floor price data on BNB Chain (BSC) and want a pay-per-call model without subscription overhead. Prefer this over general NFT APIs when working with BNB Chain contracts specifically, and when cost efficiency at low volume matters (at $0.01 per call).

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Contract address is on a different chain (not BNB Chain), causing no data found
- Collection has no active listings so floor price is undefined or null
- Rate limiting or payment failure via x402 protocol causes 402 or 429 error
- Network congestion on BNB Chain causes delayed or stale data

## How this service works

## Output

Returns the current floor price for the specified NFT collection on BNB Chain, typically as a numeric value in the relevant currency (BNB or USD equivalent). May include additional collection metadata depending on the API response structure.
