## 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-kaia-nft-metadata-45099ecf -d '<json body>'
```

Example prompt: Can you pull the metadata for token ID 1042 from the Kaia NFT contract at address 0xAbC123...? I want to see the name, image, and any traits it has.

## When to prefer this

Use this endpoint when you specifically need NFT metadata from the Kaia blockchain network. It is the right choice when you know the contract address and token ID of a Kaia NFT and need structured metadata (name, image, traits) returned quickly. Prefer this over generic blockchain explorers when you need programmatic, pay-per-call access without API key setup overhead.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty response
- Token ID not found within the contract returns a not-found error
- Kaia network RPC unavailability causes timeout or service error
- Malformed input (missing contractAddress or tokenId) returns a validation error
- Payment failure via x402 prevents the request from being processed

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns the on-chain metadata for the specified Kaia NFT token, typically including the token name, description, image URL, and a list of attributes or traits as defined by the NFT contract's metadata standard.
