# Base ERC-20 Token Intelligence Lookup

> Base ERC-20 Token Intelligence Lookup is a paid API for AI agents from fitze-x402-seller.app.workbuddy.host, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Fetches on-chain metadata for an ERC-20 token contract on Base, returning its name, symbol, decimals, and total supply.

## 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 base-erc-20-token-intelligence-lookup-4fcf8c81 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need quick, pay-per-call ERC-20 token metadata from the Base network without setting up an account or API key. Ideal for agents that need to resolve an unfamiliar contract address to human-readable token info, enrich DeFi data pipelines, or verify token identity before executing a trade or transfer. Prefer this over full blockchain RPC calls when you want a simple JSON response without managing node infrastructure.

## Known failure modes

- Invalid or non-ERC-20 contract address returns empty or error response
- Address not deployed on Base (wrong chain) may return null fields
- Non-standard ERC-20 contracts missing name/symbol/decimals may return partial data
- Malformed address (not 0x-prefixed hex) will likely cause a validation error
- Payment failure or insufficient USDC balance prevents the call from completing

## How this service works

Pay-per-call AI/data tools settled in USDC on Base via x402. No account, no API key — pay the 402 and receive the result. All endpoints also accept a bare hostname without the https:// prefix.

## Output

Returns a JSON object with the token's name, symbol, contract address, decimal precision, and total supply (as a string to handle large integers) for the queried ERC-20 contract on Base.
