Endpoint
GEThttps://chainray.online/token-approval/:var1When to prefer
Use this endpoint when you need to audit token spending permissions for a specific wallet address on a blockchain — especially useful for security reviews, identifying unlimited token approvals, or checking DeFi exposure. Prefer this over generic block explorers when you need structured, machine-readable approval data for an AI agent workflow.
Side effects
- Invalid wallet or contract address format returns an error
- Unsupported or unrecognized blockchain network returns an error
- Address with no approval history may return an empty result set
- Network congestion or RPC issues may cause timeouts
- Payment failure (x402) if USDC balance is insufficient
