Example use cases
DeFi portfolio snapshot on Sonic
“Can you pull all the token balances for my Sonic wallet 0xDeadBeef...1234 so I can see my full on-chain portfolio?”
Verify specific token holding
“Does the wallet 0xAbcdef...7890 on Sonic actually hold any of the token at contract address 0xUSDC...5678? I need to confirm before sending them funds.”
Monitor whale wallet holdings

Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/sonic/token/balances?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, pay-per-call token balance lookups specifically on the Sonic blockchain network without requiring a subscription. Ideal for agents that infrequently query balances and want to avoid rate limits or API key management. Prefer over generic RPC calls when you want structured balance data returned directly without parsing raw blockchain responses.
Side effects
- Invalid or malformed owner address returns an error or empty result
- Non-existent contract addresses return zero balances or are omitted
- Sonic network node downtime may cause timeout or 5xx error
- Missing required owner field returns a 400 bad request
- Payment not processed via x402 protocol returns 402 Payment Required
