Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/mantle/token/balances?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need token balance data on the Mantle Layer 2 network. It's ideal for DeFi agents, portfolio trackers, and eligibility checks that need fast, pay-per-call on-chain data without managing RPC infrastructure. Prefer it over self-hosted RPC calls when operating across multiple networks and needing a unified interface.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Contract address not found on Mantle network returns zero balance or error
- Network congestion or RPC unavailability causes timeout
- Payment not fulfilled via x402 protocol results in 402 response blocking access
- Empty contractAddresses array may return all tokens or require at least one entry depending on implementation
