Technical details
Endpoint
POSThttps://attest.tollkit.dev/chain/price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, accountless, pay-as-you-go on-chain token price lookup for ERC-20s or SPL mints on Base, Ethereum, or Solana. Ideal for agents that need to avoid API key management overhead and prefer micropayment-based access via x402. Best for single-token spot price checks rather than bulk historical data.
Side effects
- Invalid contract/mint address format returns a validation error
- Unsupported or unrecognized token address returns a not-found or zero-price result
- Payment failure via x402 (insufficient USDC balance or unsupported chain) blocks the request
- Network unavailability for the selected chain causes a timeout or error
- Passing a non-token contract address (e.g. a wallet or NFT) may return unexpected results
