How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns a list of token balances associated with the specified owner wallet on the opBNB network. Each entry typically includes the token contract address, token symbol or name, raw balance amount, and decimals. If specific contract addresses are provided, results are scoped to those tokens only.
Example use cases
DeFi portfolio tracker on opBNB
“Show me all the token balances for wallet 0xABC123 on opBNB so I can see the full portfolio value there.”
Verify token receipt after transfer
“Did the USDT transfer go through? Check if wallet 0xDEF456 received any USDT tokens on opBNB — the contract is 0xUSDT789.”
Multi-wallet audit for airdrop eligibility
“Pull the token balances on opBNB for address 0x111AAA to see if they hold at least 100 of the governance token at contract 0xGOV222.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/opbnb/token/balancesWhen to prefer
Choose this endpoint when you specifically need token balance data on the opBNB (BNB Layer 2) network and want pay-per-call pricing via x402 without a subscription. Prefer it over general blockchain RPC calls when you need aggregated multi-token balances in one request rather than polling individual contracts. Best for agents that need lightweight, on-demand opBNB portfolio lookups across 57+ supported networks under the same provider.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Non-existent contract address may return zero balance or error
- opBNB network downtime or RPC unavailability causes timeout
- Rate limiting or payment failure (x402) blocks the request
- Wallet with no token activity returns empty array
