## 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 nft-collection-overview-by-contract-and-chain-da5cad60
```

Example prompt: Can you pull the full collection overview for the NFT contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum — I want to see the name, symbol, contract type, whether it's flagged as spam, total supply, current owner count, and total transfers for due diligence?

## When to prefer this

Use this endpoint when you need a quick, authoritative snapshot of an NFT collection's key stats — especially for due diligence, spam detection, or verifying basic collection metadata — given a specific contract address and chain. Prefer this over on-chain RPC calls when you want indexed, aggregated data (owner count, total transfers) without building your own indexer.

## Known failure modes

- Invalid or unrecognized contract address returns an error or empty result
- Unsupported chain identifier causes a lookup failure
- Missing or invalid API key returns an authentication error
- Contract exists but is not an NFT contract, returning no meaningful collection data
- Rate limiting or payment failure (x402 payment not processed) blocks the request

## How this service works

NFT collection overview by contract and chain: name, symbol, contract type, spam flag, total supply, current owner count and total transfers, from an indexed source behind an API key. For collection due diligence. nft collection, collection stats, nft supply, owner count, nft contract info

## Output

A structured response containing the NFT collection's name, symbol, contract type (e.g. ERC-721, ERC-1155), a spam flag indicating if the collection is considered spam, the total token supply, the current number of unique owners, and the total number of transfers — all sourced from an indexed blockchain data provider.
