How this service works
The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.
Output
Returns a list of token approvals associated with the queried wallet or contract address, including approved spender contracts, token addresses, allowance amounts, and approval metadata for the specified blockchain network.
Example use cases
Audit wallet for risky approvals
“I'm concerned about my security — can you check all my token approvals across Ethereum and Polygon and tell me if any look suspicious or have unlimited allowances that I should revoke?”
Review DeFi protocol permissions
“I've been using a bunch of DeFi apps lately and want to see exactly which protocols have spending approval on my tokens. Can you list out all the token approvals on my address so I know what's connected?”
Verify contract permissions before connecting
“Before I connect my wallet to this new DeFi platform, can you check what token approvals already exist for their contract address on Arbitrum? I want to make sure they're not asking for anything unusual.”
Technical details
Endpoint
GEThttps://chainray.online/token-approval/%7Baddress%7DWhen to prefer
Use this endpoint when you need to audit token spending permissions for a specific wallet address across any of the 46 supported chains. Ideal for security audits, DeFi risk assessment, or wallet hygiene checks. Prefer this over general blockchain explorers when you need structured, agent-readable approval data with pay-per-request pricing via x402.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported chain identifier results in a chain-not-found error
- Address with no approvals returns an empty list
- Rate limiting or payment failure (x402) if USDC payment is not attached
- Network timeout for slow or congested chains
- Address does not exist on specified chain
