## How to call it through Zero

```

## When to prefer this

Use this endpoint when you need authoritative on-chain NFT collection data by contract address, especially when working with specific chains beyond Ethereum. Prefer this over general NFT APIs when you need raw blockchain intelligence rather than marketplace-curated metadata.

## Known failure modes

- Invalid or malformed contract address returns an error or empty result
- Unsupported blockchain network for the chain parameter causes a failure
- Contract address exists but is not an NFT contract may return unexpected data
- Network timeouts if the specified chain is congested or unavailable
- Missing required contract query parameter returns a 400-level error
