Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/boba/token/balancesWhen to prefer
Choose this endpoint when you specifically need ERC-20 token balance data on the Boba Network (L2). Prefer it over generic multi-chain endpoints when your query is Boba-specific. Useful for DeFi portfolio views, compliance snapshots, or wallet audits scoped to Boba. The pay-per-call x402 model makes it suitable for low-frequency lookups without subscription overhead.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Non-existent contract address returns zero balance or error
- Network downtime or Boba RPC issues cause timeouts
- Missing required 'owner' field results in a 400 bad request
- Payment failure via x402 prevents the call from executing
