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 tokeninfo-erc-20-token-metadata-lookup-559b9377 -d '<json body>'
```

Example prompt: What's the name, symbol, and number of holders for the token contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum mainnet (chain ID 1)?

## When to prefer this

Use this endpoint when you need quick, structured token metadata (name, symbol, decimals, holder count) for a known contract address on any EVM chain, especially when you already have the contract address and just need to resolve human-readable details or holder statistics. Prefer this over a generic RPC call when you want holder count specifically, which is not available via standard JSON-RPC.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Unsupported chain ID returns an error
- Contract address is not an ERC-20 token (e.g. NFT or EOA) may return incomplete data
- Network or Etherscan API timeout causes a 5xx or timeout error
- Malformed request missing required fields returns a 400 validation error

## How this service works

Pay-per-request access to CoinGecko, DefiLlama, Alchemy, and Etherscan APIs. No auth, no subscriptions.

## Output

Returns structured token metadata including the human-readable token name (e.g. 'USD Coin'), ticker symbol (e.g. 'USDC'), decimal precision (e.g. 6), and the total number of on-chain holders for the specified contract.
