## 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 zerion-api-get-nft-by-id-dfd0c498
```

Example prompt: Can you pull up the full details for the NFT at contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D token #1234 on Ethereum?

## When to prefer this

Use this endpoint when you need detailed metadata for a single, known NFT and you have its exact chain, contract address, and token ID. It is ideal for agents that need to display, verify, or analyze a specific NFT rather than searching or listing collections. Prefer this over the search/list NFT endpoint when the full NFT ID is already known and you need structured attribute data.

## Known failure modes

- Invalid NFT ID format (must be chain:contract:token_id) returns 400 Bad Request
- NFT not found or not indexed by Zerion returns 404 Not Found
- Insufficient USDC balance for x402 pay-per-call returns 402 Payment Required
- Unsupported chain identifier returns 400 or 404
- Rate limiting or overload returns 429 Too Many Requests

## How this service works

Interpreted wallet data for more than 40 chains and Solana: portfolios, DeFi positions, PnL, transactions and NFTs. REST for apps, x402 pay-per-call for agents.

## Output

A JSON object with a data field containing the NFT's resource ID, resource type, and attributes (metadata specific to that NFT such as name, image, traits, collection info), plus a links object with a self-referencing URL to the resource on the Zerion API.
