Technical details
Endpoint
POSThttps://api.arkm.com/x402/token/balanceWhen to prefer
Use this endpoint when you need real-time, per-token balance data tied to Arkham's wallet intelligence layer, especially when you want both the raw on-chain balance and a USD-denominated valuation in one call. Prefer this over generic blockchain RPC queries when you need price data alongside balance, or when building pay-as-you-go agent workflows using x402 micropayments.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported token symbol results in no data or error response
- Insufficient x402 payment causes request to be rejected
- Rate limiting if too many requests are made in quick succession
- Network or RPC issues may cause stale or unavailable balance data
