How this service works

81 paid REST endpoints covering wallet analytics, DeFi yields, token safety, smart money tracking, whale alerts, sniper detection, GMX perps, Solana tools, protocol stats, gas tracking, DEX quotes, NFT analytics, social signals, and 8 AI-powered endpoints (MiMo V2.5). Pay USDC via x402 protocol on Base.

Output

Returns a JSON object with token approval records for the specified wallet address on the given chain, including spender contract addresses, approved token amounts (including unlimited approvals), token contract details, and approval status information.

Example use cases

Wallet security audit before revoking approvals

“Check all token approvals for my wallet 0x1234567890abcdef1234567890abcdef12345678 on Ethereum — I want to see every contract that has permission to spend my tokens so I can decide which ones to revoke.”

DeFi risk check for smart money tracking

“Look up the token approval history for address 0xDeadBeef00000000000000000000000000000001 on Base chain and tell me if there are any unlimited or suspicious approvals I should know about.”

Portfolio security scan across Polygon

“Audit the token approvals for wallet 0xAbcD1234Ef5678abcd1234ef5678ABCD1234ef56 on Polygon and list all the spender contracts along with their approved amounts.”

When to prefer

Use this endpoint when you need to audit ERC-20/token spending approvals for a specific wallet address on a particular blockchain. Ideal for security audits, pre-revocation reviews, DeFi risk assessments, and smart contract permission analysis. Prefer this over generic block explorers when you need structured, machine-readable approval data that an agent can parse and act on programmatically.
