Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/worldchain/token/balancesWhen to prefer
Use this endpoint when you specifically need token balance data on the Worldchain network. It is ideal for agents building portfolio dashboards, DeFi tools, airdrop checkers, or wallet analytics that target Worldchain. It supports filtering by contract address, making it efficient for targeted balance lookups rather than broad portfolio scans.
Side effects
- Invalid or malformed owner wallet address returns an error
- Non-existent contract addresses may return zero balances or errors
- Worldchain network outage or node unavailability causes request failure
- Empty contractAddresses array may return all tokens or nothing depending on implementation
- Rate limiting or payment failure (x402) if USDC payment is not properly attached
