Example use cases
DeFi token supply audit
“Can you check the total supply for the token at 0x6B175474E89094C44Da98b954EedeAC495271d0F? I need to know how many tokens are in existence for my analysis.”
New token contract verification
“I just deployed a token at 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 — can you confirm the total supply matches what I set during deployment?”
Tokenomics research comparison

Technical details
Endpoint
GEThttps://api.api-agent-ia.ch/supply?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, low-cost lookup of a token's total supply by contract address, especially in DeFi analytics, tokenomics research, or contract verification workflows. Prefer this over calling a blockchain node directly when you want a simple REST interface without managing RPC connections.
Side effects
- Invalid or malformed token address returns an error
- Token contract does not exist on the supported chain returns empty or error response
- Network timeout if the underlying RPC node is slow
- Missing required 'token' query parameter returns a validation error
