# Phantom API — Token Metadata Lookup

> Phantom API — Token Metadata Lookup is a paid API for AI agents from phantom-api-omega.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Returns on-chain token metadata (name, symbol, decimals, supply, etc.) for a given smart contract address across 57+ blockchain networks.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-token-metadata-lookup-59c337cf -d '<json body>'
```

Example prompt: What's the name, symbol, and total supply for the token deployed at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48?

## When to prefer this

Choose this endpoint when you need fast, pay-per-call on-chain token metadata without managing RPC nodes or API keys. It is ideal for agents that need to resolve token identity (name, symbol, decimals) from a raw contract address across a wide range of EVM and non-EVM chains, especially in contexts where you want to avoid rate limits or infrastructure overhead of free public RPCs.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address is not a token contract (e.g. a plain wallet or non-ERC-20 contract)
- Unsupported network or chain not covered by the 57+ networks
- Contract exists but has no standard metadata methods (non-standard token)
- Payment failure via x402 if USDC balance is insufficient

## 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 structured token metadata for the given contract address, typically including the token name, symbol, number of decimals, and total supply, sourced directly from on-chain data across 57+ supported blockchain networks.
