# Phantom API — Unichain Token Metadata

> Phantom API — Unichain Token Metadata 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 2026-10-14).

Fetches on-chain token metadata (name, symbol, decimals, etc.) for a given ERC-20 contract address on the Unichain network

## Facts

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-unichain-token-metadata-d7b6cad3 -d '<json body>'
```

Example prompt: What's the name, symbol, and decimals for the Unichain token at contract address 0x1234abcd...?

## When to prefer this

Use this endpoint when you need fast, pay-per-call token metadata specifically from the Unichain network. Prefer it over general-purpose blockchain explorers when you need programmatic, low-latency access to token name/symbol/decimals without API key setup, and when Unichain is the target chain.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address exists but is not an ERC-20 token (no metadata methods) — may return empty or error
- Contract not deployed on Unichain — returns not found or empty response
- Network or RPC outage causes timeout
- Payment failure via x402 prevents the call from completing

## 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 Unichain token contract, typically including the token name, symbol, and decimal precision as stored in the smart contract.
