# Mint Intel: ERC-20 Token Metadata on Base

> Mint Intel: ERC-20 Token Metadata on Base is a paid API for AI agents from mintintel.35-171-220-195.sslip.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-31).

Returns ERC-20 token metadata (name, symbol, decimals) and total supply (raw and decimal-adjusted) for any token contract on the Base blockchain in a single batched eth_call.

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 mint-intel-erc-20-token-metadata-on-base-9c656eaa
```

Example prompt: What's the name, symbol, decimals, and total supply of the ERC-20 token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base?

## When to prefer this

Use this endpoint when you need ERC-20 token metadata and total supply on Base in a single call without managing your own RPC node or API key. It is ideal for DeFi dashboards, token validation before swaps, portfolio enrichment, and any workflow needing fast, on-chain Base token info. Prefer this over general Ethereum endpoints when the token is specifically on Base (not Ethereum mainnet).

## Known failure modes

- 404 if the contract address is not a recognized ERC-20 token on Base (not charged)
- Invalid or malformed 0x address returns an error
- Non-existent contract address (no bytecode) returns 404
- Network or RPC timeout may cause intermittent failures
- Token contracts that do not implement standard ERC-20 name/symbol/decimals may fail or return partial data

## How this service works

ERC-20 token metadata and total supply on Base via eth_call: name, symbol, decimals and totalSupply (raw + decimal-adjusted) in one batch. Not a token -> 404, not charged.

## Output

A JSON object containing the token's name, symbol, decimals (integer), totalSupplyRaw (string, wei-scale), and total supply adjusted to human-readable decimal form. Returns a 404 (not charged) if the address is not a valid ERC-20 token on Base.
