How this service works
Cheap, factual EVM chain lookups priced per call in USDC. Base, Polygon, Arbitrum, Optimism and Ethereum.
Output
Returns a JSON object with the token's name, symbol, decimals, contract address, chain, and total supply (both raw integer and human-readable decimal amount formatted using the token's decimals).
Example use cases
Verify token contract identity
“Can you confirm the name and symbol of the token at contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base? I want to make sure it's actually USDC before I interact with it.”
Check token decimals for DeFi integration
“What are the decimals for the WETH token at 0x4200000000000000000000000000000000000006 on Optimism? I need it to correctly format amounts in my app.”
Audit total supply of a token
“Look up the total supply of the token at contract 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Polygon — give me both the raw number and the human-readable amount.”
Technical details
Endpoint
GEThttps://multichain-rpc.clankerceo.workers.dev/token-metadataWhen to prefer
Choose this endpoint when you need fast, cheap on-chain ERC-20 token metadata lookups across Base, Polygon, Arbitrum, Optimism, or Ethereum without running your own RPC node. At $0.002 per call, it is cost-effective for per-call agent workflows. Prefer this over general-purpose RPC providers when you specifically need token name, symbol, decimals, and supply in a single normalized JSON response priced in USDC via x402.
Side effects
- Invalid or non-existent contract address returns an error or empty response
- Unsupported chain name results in a bad request error
- Non-ERC-20 contract address (e.g. NFT or EOA) may return null or incomplete metadata
- Network congestion on the underlying RPC may cause timeouts
- Payment failure (x402) if USDC allowance is insufficient
