Example use cases
DeFi portfolio snapshot for a wallet
“Can you pull the token balances for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 for these two contracts: 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and 0x6B175474E89094C44Da98b954EedeAC495271d0F?”
Check if airdrop wallet received tokens
“Has wallet 0x1234abcd...5678 received any balance from this token contract 0xdeadbeef...cafe? I want to verify the airdrop landed.”
Monitor whale wallet token holdings
“Look up the current token balances for the wallet 0xBigWhale...999 across these five token contracts so I can see what degen coins they're holding right now.”

Endpoint
POSThttps://synapse-api-brown.vercel.app/api/degen/token/balancesWhen to prefer
Choose this endpoint when you need to quickly look up ERC-20 token balances for a specific wallet address across one or more token contracts on supported blockchain networks. It is well-suited for DeFi portfolio checks, airdrop verification, whale wallet monitoring, or any scenario requiring fast per-call token balance data without setting up a full blockchain node. Prefer it when paying per-call via x402 is acceptable and you need results across 57+ supported chains.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Non-existent or unsupported contract address may return zero balance or an error
- Network or RPC outage for the target blockchain chain may cause lookup failure
- Payment failure via x402 results in a 402 response and no data returned
- Requesting balances on an unsupported blockchain network may return an error
