Example use cases
DeFi portfolio valuation
“I need the current prices for these two tokens on Ethereum: USDC at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and USDT at 0xdAC17F958D2ee523a2206206994597C13D831ec7 — can you fetch those for me?”
Arbitrage opportunity check
“Quickly grab the price of the WETH token on Ethereum at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 so I can compare it to the price on another exchange.”
Token price alert monitoring
“Look up the current price for the ARB token on Arbitrum at 0x912CE59144191C1204E64559FE8253a0e49E6548 — I want to know if it's above $1.”
Technical details
Endpoint
POSThttps://x402engine.app/api/token/prices?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic, pay-per-call on-chain token price lookups without a long-term API subscription — especially useful for AI agents that need real-time token prices across multiple chains (Ethereum, Base, Solana, MegaETH) and want to pay per query in USDC via the x402 micropayment protocol.
Side effects
- Invalid or unrecognized chain name returns an error
- Unknown or incorrect token_address returns no price data or an error
- Empty tokens array rejected due to minItems:1 constraint
- Network or upstream price feed unavailability causes timeout or 5xx error
- Payment failure via HTTP 402 if USDC/USDC balance is insufficient
