How this service works
Token price by contract address, live from the chain ($0.001): USD price of any ERC-20 on Base, Ethereum, Arbitrum, Optimism or Polygon from a simulated $100 buy and sale on the best DEX route (Uniswap v2/v3/v4, Aerodrome), with buy and sell price, round-trip cost as a liquidity gauge, total supply and fully diluted value. Use for the current price of any token, including ones too new for price APIs.
Output
Returns the live USD buy price, USD sell price, round-trip cost (as a liquidity gauge), the DEX route used (Uniswap v2/v3/v4 or Aerodrome), total token supply, and fully diluted value — all derived from a simulated $100 buy and sell on-chain.
Example use cases
New token launch price check
“I just found a brand new token on Base with contract 0x940181a94a35a4569e4529a3cdfb74e38fd98631 — it's too new to be on CoinGecko or CoinMarketCap. Can you get me the live on-chain buy and sell price, plus the fully diluted valuation?”
DeFi liquidity spread analysis
“Can you check the buy/sell spread for the Ethereum token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — I want to know the round-trip cost as a measure of how liquid it is before I trade it?”
Portfolio token valuation on Arbitrum
“What's the current USD price and total supply for the token at contract 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 on Arbitrum, using the best Uniswap DEX route available?”
Technical details
Endpoint
GEThttps://api.marketintelligenceapi.com/api/v1/intelligence/token-price/:address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the live on-chain price of any ERC-20 token — especially newly launched tokens not yet indexed by aggregators like CoinGecko or CoinMarketCap. Prefer this over traditional price APIs when you need real DEX-sourced prices with liquidity context (buy/sell spread, round-trip cost) rather than aggregated last-trade prices. It is especially valuable for DeFi agents, trading bots, and portfolio tools that must handle tokens across Base, Ethereum, Arbitrum, Optimism, and Polygon by their raw contract addresses.
Side effects
- Contract address not found on the specified chain — returns error or empty result
- Token has no liquidity pool on any supported DEX — price simulation fails
- Invalid or malformed contract address (non-0x or wrong length) — returns validation error
- Unsupported chain specified — returns 400-level error
- Network or RPC outage causes stale or failed simulation — returns error or timeout
