How this service works
Wallet balances, tokens, transactions and prices on Base, Ethereum and Solana. Other Tollkit tools are described at: https://extract.tollkit.dev/openapi.json, https://attest.tollkit.dev/openapi.json, https://web.tollkit.dev/openapi.json, https://data.tollkit.dev/openapi.json.
Output
Returns a JSON object with the token's symbol, current USD price, the DEX and pool it was priced from, the fee tier, the quote token used, the UTC timestamp of pricing, pool depth in USD, and a low-liquidity boolean flag.
Example use cases
DeFi portfolio valuation
“I need the current USD price of the token at 0x4200000000000000000000000000000000000006 on Base so I can calculate my portfolio value.”
Pre-trade price check
“Before I swap, can you tell me the live on-chain price in USD for the Solana token with mint address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v?”
Liquidity alert monitoring
“Check the price and liquidity depth of the Ethereum token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — I want to know if liquidity is low before I make a large trade.”
Technical details
Endpoint
POSThttps://chain.tollkit.dev/chain/price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-time on-chain USD price for a specific ERC-20 or SPL token by its contract address on Base, Ethereum, or Solana, without requiring an API key — paying per call in USDC via x402. It is especially useful when you want the DEX source and pool metadata alongside the price, or when you need to check pool liquidity depth before executing a trade.
Side effects
- Invalid or malformed contract/mint address returns a validation error
- Token not found on the specified chain returns no price data
- Token exists but has no active DEX pool and cannot be priced
- Low liquidity flag is true, indicating the price may not be reliable for large trades
- Unsupported chain value returns an enum validation error
- Network or RPC timeouts may delay or fail the response
