# Vextorium ERC-20 Token Info

> Vextorium ERC-20 Token Info is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-15).

Reads ERC-20 token metadata (name, symbol, decimals, total supply, proxy status) directly from a contract on Base or Ethereum.

## 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 vextorium-erc-20-token-info-610b8ccb -d '<json body>'
```

Example prompt: Can you pull the on-chain details for the USDC token contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — I need the name, symbol, decimals, total supply, and whether it's an upgradeable proxy?

## When to prefer this

Use this endpoint when you need authoritative, on-chain ERC-20 token metadata directly from the contract rather than relying on off-chain token lists or price aggregators. It is especially valuable for verifying unknown tokens, auditing contracts before integration, or checking whether a token is upgradeable — particularly on Base or Ethereum mainnet.

## Known failure modes

- Contract address does not exist on the specified network — returns null fields or error
- Address provided is not an ERC-20 token contract (e.g. an EOA or a non-token contract) — fields may be null
- Wrong network specified (e.g. contract is on Ethereum but Base was requested) — returns empty or null data
- Malformed contract address (not a valid EVM hex address) — validation error
- Network RPC timeout or congestion — request may fail or return partial data

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

A JSON object containing the token's on-chain name, symbol, decimal places, total supply (as a human-readable number), and a boolean indicating whether the contract is an upgradeable EIP-1967 proxy — plus the implementation address if it is one.
