How this service works
Pay-per-call utility APIs in USDC on Base: Hebrew calendar and text tools, Shabbat times, Base token control-risk screen and address summary, plus finance arithmetic tools. General information and arithmetic only; not investment, tax or legal advice and not a recommendation to buy, sell or hold anything.
Output
A JSON object with two fields: 'decimals' (integer indicating how many decimal places the token uses, e.g. 6 for USDC) and 'total_supply' (string representing the raw total supply of the token, in its smallest unit).
Example use cases
Token supply due diligence check
“I'm looking at a new token on Base — can you pull the total supply and decimals for contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 so I can see how many tokens exist?”
DeFi protocol token audit
“For our internal report, fetch the on-chain total supply and decimal precision for the Base ERC-20 token at 0x4200000000000000000000000000000000000006.”
Portfolio app token metadata fetch
“I need the total supply and number of decimal places for the token deployed at 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb on Base to display it correctly in our app.”
Technical details
Endpoint
GEThttps://heb-utils-x402.hebutils-api.workers.dev/base-erc20-supply?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick, pay-per-call on-chain lookup of ERC-20 total supply and decimals specifically on the Base L2 network, without setting up your own RPC infrastructure. Particularly useful for agents that need sporadic, low-cost token metadata lookups rather than bulk data pipelines.
Side effects
- Invalid or missing token address returns an error response
- Non-existent contract address on Base yields no data or an error
- Network or RPC timeout causes call failure
- Payment failure (insufficient USDC balance) blocks the request via x402 protocol
