# Phantom API — Mantle Token Metadata

> Phantom API — Mantle 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 2026-10-22).

Fetches on-chain token metadata (name, symbol, decimals, etc.) for a given contract address on the Mantle 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-mantle-token-metadata-e67954b9 -d '<json body>'
```

Example prompt: Can you look up the token metadata — name, symbol, and decimals — for the Mantle contract at 0x78c1b0C915c4FAA5FffA6CAbf0219DA63d7f4cb8?

## When to prefer this

Use this endpoint when you specifically need token metadata from the Mantle network (MNT chain). Prefer this over generic block explorers when you need programmatic, structured JSON output for ERC-20 token details at $0.01 per call via x402 micropayments, especially inside automated agent workflows that process multiple Mantle token addresses.

## Known failure modes

- Invalid or malformed contract address returns an error
- Non-token contract address (e.g. a plain wallet or non-ERC-20 contract) may return empty or partial metadata
- Contract not deployed on Mantle network returns not-found error
- Network congestion or RPC issues may cause timeouts
- Payment failure via x402 if wallet has insufficient USDC

## 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 token metadata for the specified Mantle contract address, typically including the token name, symbol, number of decimals, and potentially total supply or other ERC-20 standard fields stored on the contract.

## Request schema (JSON Schema)
