## 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 collectablespulse-nft-floor-price-contract-safety-check-eba509b9
```

Example prompt: Before I buy into this NFT collection, can you run a safety scan on contract address 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13d on Ethereum and also tell me the 24-hour floor price, volume, and sales count?

## When to prefer this

Use this endpoint when an AI agent or NFT trading bot needs a pre-purchase due-diligence check combining both market data (floor price, volume, sales) and on-chain security analysis (GoPlus) for NFT collections on Ethereum, Base, Polygon, or Arbitrum — especially when the goal is to avoid scam, rug pull, or trap contracts before executing a buy.

## Known failure modes

- Invalid or unrecognized contract address returns an error or empty result
- Unsupported chain/network returns an error
- GoPlus API unavailability may cause safety data to be missing or degraded
- Contract with no trading history returns zero floor price and volume
- Rate limiting or payment failure (x402) blocks the request

## Output

Returns a structured response including the collection's 24-hour floor price, trading volume, and number of sales, plus a GoPlus-powered on-chain contract safety report flagging risks such as hidden mint functions, burn traps, approval traps, counterfeit/malicious contract indicators, and an overall safety score — across Ethereum, Base, Polygon, and Arbitrum.
