## 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-base-token-metadata-b19b32d3 -d '<json body>'
```

Example prompt: Can you pull the token metadata for the contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — I want to know the name, symbol, and decimals.

## When to prefer this

Choose this endpoint when you need fast, pay-per-call token metadata specifically on the Base network without needing a subscription or API key. Ideal for agents that need lightweight, on-demand token lookups (name, symbol, decimals) for a specific contract address without pulling full indexer data.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address does not correspond to a token contract (e.g. a non-ERC-20 contract) may return empty or error
- Network unavailable or RPC issues may cause timeout
- Payment failure via x402 protocol results in 402 response and no data returned
- Contract deployed on a different network (not Base) will not return valid metadata

## 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 metadata for the specified Base network token contract, typically including the token name, symbol, and decimal precision as stored in the smart contract.
