Output
Returns a JSON object containing the token's name, symbol, decimals, raw total supply (as a big integer string), and decimal-adjusted total supply, along with the chain and contract address echoed back for confirmation.
Example use cases
DeFi token due-diligence check
“Before I invest, can you look up the on-chain metadata for contract 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 on Ethereum — specifically the name, symbol, decimals, and total supply?”
Supply tracking for a new Base token
“I need to track the total supply of this new token on Base — the contract address is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913. Can you fetch its name, symbol, decimals, and current total supply from on-chain?”
Token explorer data enrichment
“For my token explorer dashboard, can you fetch the ERC-20 metadata for contract 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum, including the raw and decimal total supply?”
Technical details
Endpoint
POSThttps://agent-commerce-factory-jm.austriaeast.cloudapp.azure.com/v1/onchain/token-metaWhen to prefer
Use this endpoint when you need authoritative, live on-chain ERC-20 token metadata (name, symbol, decimals, supply) directly from the blockchain rather than from a cached or aggregated data source. Prefer it over CoinGecko-style endpoints when you need the raw contract-level truth, or when the token is too new or niche to appear in market data APIs. Also ideal when you need the exact totalSupplyRaw for smart contract interactions.
Side effects
- Invalid or non-ERC-20 contract address returns null fields or an error
- Unsupported chain name causes a validation error
- Contract address that exists but is not an ERC-20 token may return partial or null metadata
- Network RPC issues may cause transient failures or timeouts
- Malformed contract address pattern (not matching 0x + 40 hex chars) rejected by schema validation
