Endpoint
POSThttps://leoshi-blog.vercel.app/api/market/balance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call balance lookup for a specific token and wallet address without needing to set up a full blockchain node or subscription-based indexing service. Particularly suited for lightweight agents that need occasional on-chain balance checks rather than continuous monitoring.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported token symbol returns an error or empty result
- Network or RPC connectivity issues may cause timeouts
- Rate limiting may occur under high request volume
