Verify airdrop token receipt
“I just received an airdrop on Gnosis — can you check if wallet 0xDef7...1234 has a balance for the token contract 0xAbcToken...5678?”

Endpoint
POSThttps://synapse-api-brown.vercel.app/api/gnosis/token/balancesWhen to prefer
Choose this endpoint when you specifically need ERC-20 token balances on the Gnosis (xDai) blockchain. It is distinct from Ethereum mainnet or other EVM chain balance endpoints and is ideal for agents auditing DeFi positions, DAOs, or personal wallets operating within the Gnosis ecosystem.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Non-existent contract addresses may return zero balances or errors
- Rate limiting or payment failure (x402) blocks the call
- Gnosis RPC node downtime may cause timeouts
- Empty contractAddresses array may return all tokens or none depending on implementation
