How this service works
Live on-chain token metadata for an ERC-20 or ERC-721 contract (Base, Ethereum, Polygon, Arbitrum, Optimism; keyless). Returns name, symbol, decimals, detected standard, and total supply (raw + formatted). The authoritative read straight from the contract — complements crypto.token-price and crypto.contract (ABI/source).
Output
Returns the token's on-chain name, symbol, number of decimals, detected token standard (ERC-20 or ERC-721), and total supply in both raw integer form and human-readable formatted form — read directly from the contract.
Example use cases
Example prompt
“What's the name, symbol, decimals, and total supply of the token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum?”
Technical details
Endpoint
GEThttps://2s.io/api/crypto/token-metadataWhen to prefer
Use this endpoint when you need authoritative, live on-chain token metadata (name, symbol, decimals, total supply, token standard) directly from the contract — not from a centralized index that may be stale. Ideal for verifying token details before a swap, enriching a portfolio view, or confirming ERC standard. Complements price endpoints (which give market data) and ABI/source endpoints (which give contract code).
Side effects
- Invalid or non-existent contract address returns an error or empty metadata
- Contract address exists but is not an ERC-20 or ERC-721 (e.g. proxy, multisig) — standard may be undetectable
- Unsupported chain value returns validation error
- Network congestion or RPC issues may cause delayed or failed on-chain reads
- Payment failure (x402) if USDC balance is insufficient
