Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/ronin/token/balancesWhen to prefer
Use this endpoint when you specifically need token balance data on the Ronin blockchain (Sky Mavis / Axie Infinity ecosystem). Prefer this over generic blockchain balance APIs when your use case involves Ronin-native tokens like RON, SLP, AXS, or USDC on Ronin.
Side effects
- Invalid or malformed owner wallet address returns an error
- Non-existent or incorrect contract address returns zero balance or error
- Ronin RPC node unavailability causes timeout
- Missing required 'owner' field causes 400 bad request
- Rate limiting or payment failure via x402 blocks the call
