Example use cases
DeFi token supply verification
“Can you pull the current supply data for the USDC token at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base so I can check its circulating supply?”
Token analytics dashboard enrichment
“I'm building a dashboard — fetch the supply figures for the ERC-20 at 0x4200000000000000000000000000000000000006 on Base so I can show circulating supply stats.”
On-chain due diligence for new token
“Before I invest, can you look up the total supply for this new token at contract address 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA on Base?”
Technical details
Endpoint
GEThttps://chainverdict.xyz/v1/data/supply/%7Btoken%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain token supply data specifically for ERC-20 contracts deployed on the Base network, and you are set up to handle x402 micropayments ($0.003 USDC per call). Prefer this over general blockchain explorers when you need programmatic, API-accessible supply data for Base tokens in an agent workflow.
Side effects
- Invalid or malformed ERC-20 contract address returns an error
- Contract address not found on Base network returns empty or error response
- Unpaid request returns HTTP 402 with x402 payment requirements
- Non-ERC-20 contract address may return unexpected or empty supply data
- Rate limiting or network issues may cause timeouts
