How this service works
Use when you need name, symbol, decimals and total supply of an ERC-20 token on Base, Ethereum, Arbitrum, Optimism or Polygon in one call, with the supply formatted by decimals.
Output
Returns a JSON object containing the token's human-readable name, ticker symbol, number of decimals, and total supply formatted as a human-readable number (already divided by the token's decimal precision), all retrieved in a single on-chain call.
Example use cases
Identify unknown token by contract address
“I found this contract address 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum — can you tell me what token it is, its symbol, how many decimals it uses, and what the total supply looks like?”
DeFi dashboard token info enrichment
“I'm building a dashboard and need the name, symbol, decimals, and formatted total supply for the token at 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Polygon.”
Compare token supplies across chains
“What are the full metadata details — name, symbol, decimals, and total supply — for the USDC token at 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 on Arbitrum?”
Technical details
Endpoint
GEThttps://biosfera.46-62-215-147.sslip.io/o/erc20-metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need all four standard ERC-20 metadata fields (name, symbol, decimals, total supply) in a single call and want the total supply pre-formatted by decimals — avoiding multiple separate RPC calls. Prefer it over raw blockchain RPC queries when you need a simple REST interface across Base, Ethereum, Arbitrum, Optimism, or Polygon without managing provider connections yourself.
Side effects
- Invalid or non-ERC-20 contract address returns an error or empty metadata
- Unsupported chain value results in a validation error
- Contract exists but doesn't implement ERC-20 standard methods, causing partial or failed response
- Network congestion may increase latency or cause timeouts
- Malformed address (not matching 0x + 40 hex chars) is rejected by input validation
