x402
Vextorium ERC-20 Token Supply & Concentration is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-19).
Returns total minted, burned, approximate circulating supply, and contract owner balance/share for any ERC-20 token — a concentration and issuer-control signal.

How this service works
558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.
Output
A JSON object containing the token's name, symbol, network, decimals, total supply, burned amount (tokens sent to dead addresses), burned percentage, approximate circulating supply, and — if applicable — the contract owner's address and balance/share, all as numeric and string fields.
Example use cases
Token burn rate due diligence
“Before I invest, can you check how much of the SHIB token has been burned and what percentage of the supply the contract owner holds on Ethereum?”
DeFi protocol risk assessment
“I'm auditing this DeFi token on Base at contract 0xabc123… — can you tell me the total minted supply, how much has been burned to dead addresses, and whether the deployer still holds a large share?”
Circulating supply verification for listing
“We're listing a new ERC-20 token on Arbitrum at address 0xdef456… and need the exact total supply, approximate circulating supply after burns, and the owner's current balance for our listing form.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/token-supply?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick on-chain snapshot of an ERC-20 token's supply economics — especially total vs. circulating supply, burn metrics, and owner concentration risk — across the five major EVM networks (Ethereum, Base, Arbitrum, Optimism, Polygon). Prefer it over generic block explorer lookups when you want a pre-computed, structured concentration signal without writing custom RPC calls.
Side effects
- Invalid or non-ERC-20 contract address returns an error or empty result
- Unsupported network (not base, ethereum, arbitrum, optimism, or polygon) returns a validation error
- Contract exists but has no detectable owner (owner field returns null)
- Dead-address burn detection is approximate and may miss non-standard burn mechanisms
- RPC latency on the target chain may cause timeout or stale data
