How this service works
Pay-per-call product page extraction. No account, no API key: pay in-band with x402 in USDC on Base or Solana.
Output
Returns the current on-chain price of the specified token (by contract or mint address) in USDC, fetched from the requested chain (Base, Ethereum, or Solana). Response includes the price figure and likely token metadata such as symbol or address confirmation.
Example use cases
DeFi portfolio token valuation
“What's the current price of the token at contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base? I need to value my position.”
Solana SPL token price check
“Can you look up the price of the SPL token with mint address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v on Solana?”
Cross-chain price comparison
“Get me the current on-chain price of the token at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 on Ethereum and then do the same for its equivalent on Base so I can compare them.”
Technical details
Endpoint
POSThttps://web.tollkit.dev/chain/price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-call, no-account on-chain token price lookup for Base, Ethereum, or Solana tokens identified by contract address. Ideal for agents that handle crypto wallets or DeFi workflows and want to avoid API key management by paying inline via x402 in USDC. Prefer this over centralized exchange price APIs when you need the actual on-chain (DEX) price rather than a CEX order-book price.
Side effects
- Invalid token address format — returns 400 if the contract address doesn't match ERC-20 or SPL pattern
- Unsupported chain value — must be 'base', 'ethereum', or 'solana'
- Token not found or not priced on the selected chain — may return null price or 404
- Payment failure via x402 — call fails if USDC payment on Base/Solana cannot be processed
- Network or RPC timeout — on-chain lookup may time out under congestion
