Endpoint
POSThttps://x402engine.app/api/token/pricesWhen 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
