# ERC20 Token Info

> ERC20 Token Info is a paid API for AI agents from flat-rate-llm.kikoribera03.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns the name, symbol, decimals, and total supply of any ERC20 token contract in a single call across major EVM chains.

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 erc20-token-info-9fec76bb -d '<json body>'
```

Example prompt: Can you look up the name, symbol, decimals, and total supply for the ERC20 contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum?

## When to prefer this

Use this endpoint when you have an ERC20 contract address and need to display or process it in a human-readable way — getting the name, symbol, decimals, and supply in one call instead of making multiple RPC calls. Prefer this over raw RPC calls when you need a simple, paid, rate-stable lookup across Ethereum, Base, Polygon, Arbitrum, or Optimism without managing your own node infrastructure.

## Known failure modes

- Invalid or non-ERC20 contract address returns an error or empty fields
- Unsupported chain name returns a validation error
- Contract address exists but is not an ERC20 (e.g. NFT or proxy with no standard methods) may return nulls or revert
- Network timeout or RPC failure for the target chain
- Malformed address format triggers input validation error

## How this service works

60 paid endpoints with no metering, no API key and no account. Each endpoint has one flat price per call, whatever the size of the request: LLM completions with automatic failover across several large models, read-only EVM tooling over Base, Ethereum, Polygon, Arbitrum and Optimism, and pure crypto utilities that touch no network.

## Output

A JSON object containing the token's full name (e.g. 'USD Coin'), ticker symbol (e.g. 'USDC'), number of decimals (e.g. 6), and raw total supply as an integer string (e.g. '5000000000000').
