How this service works
Cheap, factual EVM chain lookups priced per call in USDC. Base, Polygon, Arbitrum, Optimism and Ethereum.
Output
A JSON object containing the token's name, symbol, chain, contract address, decimals (integer), and total supply expressed both as a raw integer string and a human-readable decimal amount.
Example use cases
Token decimals check for DeFi integration
“I need to know the decimals for the token at contract 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Polygon — we're integrating it and need to format amounts correctly.”
Verify token identity before trading
“Before I swap, can you confirm what token lives at 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 on Arbitrum — give me its name, symbol, and total supply.”
Audit total supply for a Base token
“What's the current total supply of the token at contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base? I want to check if new tokens have been minted recently.”

Endpoint
GEThttps://multichain-rpc.clankerceo.workers.dev/erc20-tokenWhen to prefer
Choose this endpoint when you need lightweight, per-call ERC-20 token metadata across multiple EVM chains without running your own RPC node. It is ideal for agents that need to resolve token decimals, names, or supply figures on Base, Polygon, Arbitrum, Optimism, or Ethereum cheaply ($0.002/call) and without managing API keys for individual chain providers.
Side effects
- Invalid or non-ERC-20 contract address returns an error or empty response
- Unsupported chain name returns an error
- Contract address with no deployed code returns an error
- Network congestion on the target chain may cause timeouts
- Malformed query parameters (missing chain or contract) return a 400-level error
