# Phantom API — Ethereum Token Metadata

> Phantom API — Ethereum 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 2026-10-10).

Fetches on-chain metadata for an Ethereum ERC-20 or NFT token given its contract address

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-ethereum-token-metadata-5389cb6b -d '<json body>'
```

Example prompt: Can you pull the token metadata for the Ethereum contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — I need the name, symbol, and decimals?

## When to prefer this

Use this endpoint when you need fast, pay-per-call on-chain token metadata for Ethereum contracts without managing your own RPC infrastructure or API keys. Ideal for agents that need occasional token lookups rather than high-volume streaming, and when cost predictability at $0.01/call is acceptable.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address exists but is not a token contract (no metadata interface) may return empty or error
- Network congestion or RPC issues may cause timeouts
- Non-Ethereum contract addresses (e.g. Solana) will not be valid for this endpoint
- Payment failure via x402 results in 402 response before data is returned

## 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 Ethereum token contract, including token name, symbol, number of decimals, and potentially token standard (ERC-20, ERC-721, etc.). Response is sourced directly from blockchain data across supported networks.
