## 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-avalanche-nft-metadata-b0083094 -d '<json body>'
```

Example prompt: Can you pull the metadata for token ID 42 from the Avalanche NFT contract at 0xAbC1234567890abcdef1234567890abcdef123456? I want to see the name, image, and attributes.

## When to prefer this

Choose this endpoint when you need fast, pay-per-call NFT metadata lookups specifically on the Avalanche (AVAX) network without setting up your own RPC infrastructure. Ideal for agents that need occasional on-demand metadata rather than bulk indexed queries, and for applications that want micropayment-based access via x402 without API key management.

## Known failure modes

- Invalid contract address format returns an error or empty response
- Token ID does not exist on the contract, resulting in a not-found error
- Contract is not a valid NFT contract (e.g. ERC-20), causing a metadata resolution failure
- Avalanche RPC node unavailability leads to timeout or upstream error
- Metadata URI is off-chain and unreachable, returning incomplete data

## 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 on-chain NFT metadata for the specified Avalanche token, typically including the token name, description, image URL, and any custom attributes or traits defined in the contract's metadata URI.
