## 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-bnb-nft-metadata-lookup-03d9dd7b -d '<json body>'
```

Example prompt: Can you pull the metadata for token ID 1234 from the BNB Smart Chain NFT contract at 0xBd8A7ea8CFE89F6Bc15d3B7653EB06Da4567 — I need its name, image, and traits.

## When to prefer this

Use this endpoint when you specifically need NFT metadata from the BNB Smart Chain (BSC) network and want a pay-per-call model without managing RPC infrastructure. Prefer it over general-purpose blockchain explorers when you need structured metadata (name, image, traits) rather than raw transaction data, and when you want fast, reliable access without running your own BNB node.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty metadata
- Token ID not found within the contract returns a 404-style or null response
- Contract is not an NFT contract (e.g. ERC-20) causing a schema mismatch error
- Token metadata URI is unreachable or returns malformed JSON
- Network congestion or RPC issues on BNB Smart Chain causing timeouts
- Payment failure via x402 protocol resulting in 402 Payment Required

## 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 token on BNB Smart Chain, including fields such as token name, description, image URL, external URL, and an array of trait attributes (trait_type and value pairs), sourced directly from the blockchain or the token's metadata URI.
