How this service works
On-chain intelligence for AI agents. 70+ endpoints across Base, Arbitrum, Solana. x402 micropayments.
Output
Returns a JSON object containing the list of token approvals associated with the given wallet address on the specified chain, including spender contract addresses, approved token amounts, and approval status details.
Example use cases
Wallet security audit before token revoke
“Check all the token approvals on my Arbitrum wallet 0x1234abcd5678ef... — I want to see every contract that has permission to spend my tokens so I can figure out which ones to revoke.”
DeFi protocol risk assessment
“Look up the token approvals for address 0xDeadBeef9876... on Base — I need to know if any unlimited allowances are set for any DeFi contracts.”
Suspicious activity investigation
“Can you check the token approvals on this Solana address AbCdEfGh1234... and tell me if anything looks off, like unknown contracts with large or unlimited spending permissions?”
Technical details
Endpoint
GEThttps://ragdar.vercel.app/api/approvals/%7Bchain%7D/%7Baddress%7DWhen to prefer
Choose this endpoint when you need to audit or inspect on-chain token approvals (ERC-20 allowances or equivalent) for a specific wallet address on Base, Arbitrum, or Solana. It is particularly useful for security audits, DeFi risk management, or pre-revocation checks. Prefer this over generic blockchain explorers when you need structured, agent-consumable data with micropayment access via x402.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Unsupported chain identifier causes a bad request response
- Address with no approvals returns an empty approvals array
- Network congestion or RPC issues may cause timeouts
- Rate limiting if too many requests are made in quick succession
