Alchemy Prices API — Current Token Prices by Contract Address

Use this endpoint when you have specific token contract addresses (not symbols) and need current real-time prices, especially for less common or chain-specific tokens where a symbol lookup might be ambiguous. Prefer this over the symbol-based endpoint when you know the exact contract address to avoid symbol collision across chains.

• Invalid or unrecognized contract address returns an error or null price
• Unsupported chain results in an error response
• Rate limiting or payment failure via x402 protocol returns 402 Payment Required
• Malformed request body returns 400 Bad Request
• Token exists on chain but has no price data available
