## 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 synapse-api-zora-token-metadata-5e35f1fa -d '<json body>'
```

Example prompt: Can you pull the token metadata for the Zora NFT contract at 0x3B3ee1931Dc30C1957379FAc9aba94D1C48a5405 — I need the name, symbol, and token URI?

## When to prefer this

Use this endpoint when you specifically need Zora protocol NFT contract metadata and want a pay-per-call model without managing your own blockchain RPC infrastructure. Prefer this over direct RPC calls when you want a simple REST interface to Zora token data without setting up a Web3 provider.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address not found on Zora protocol returns empty or null result
- Non-Zora contract address may return no meaningful metadata
- Network or RPC timeouts on blockchain queries
- Payment failure via x402 prevents endpoint access
