# Token Metadata Lookup

> Token Metadata Lookup is a paid API for AI agents from chain.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Reads ERC-20 token metadata on-chain (name, symbol, decimals, total supply, owner, proxy implementation, holder count, reputation) across Base, Ethereum, Arbitrum, Optimism, Polygon, and BSC.

## 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 token-metadata-lookup-e121a7ec
```

Example prompt: What are the on-chain details for the token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — give me the name, symbol, decimals, total supply, owner, whether ownership is renounced, and the holder count.

## When to prefer this

Use this endpoint when you need comprehensive, on-chain ERC-20 token metadata in a single call, especially when you need to verify ownership renouncement, detect proxy contracts, or check holder count and reputation as part of due diligence. Prefer it over DEX-price or security-scan endpoints when your primary need is token identity and contract structure rather than price or vulnerability data. Its multi-chain support (Base, Ethereum, Arbitrum, Optimism, Polygon, BSC) via simple prefix syntax makes it ideal for cross-chain token research.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Non-ERC-20 contract address (e.g., plain EOA or non-token contract) may return partial or no data
- Unsupported chain prefix returns an error
- Rate limiting or payment failure ($0.01 USDC per call) blocks the request
- Proxy implementation undetectable if not EIP-1967 compliant — field may be null
- Holder count may be approximate or delayed depending on indexer freshness

## How this service works

ERC-20 token metadata read on-chain: name, symbol, decimals, total supply, owner (and whether renounced), EIP-1967 proxy implementation, holder count and reputation. Default chain Base; prefix another: ethereum:, arbitrum:, optimism:, polygon:, bsc:. $0.01 per call.

## Output

Returns structured on-chain metadata for the ERC-20 token: official name, ticker symbol, decimal precision, total supply, owner wallet address, boolean indicating whether ownership has been renounced, EIP-1967 proxy implementation address (if applicable), number of holders, and a reputation score. Defaults to Base chain unless a chain prefix is specified.
