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 on the given chain, including spender contract addresses, approved token details, allowance amounts (including whether they are unlimited), and approval status.

Example use cases

Audit wallet before DeFi exit

“Check all token approvals on my Ethereum wallet 0xDEF...456 — I want to know which contracts still have permission to spend my tokens before I revoke anything.”

Security review after suspicious activity

“My Polygon wallet 0x789...ABC was drained — can you look up all current token approvals on that address so I can see which contract had access?”

Pre-trade approval risk check

“Before I swap on this new DEX, can you check my Arbitrum wallet 0x111...222 for any unlimited token approvals that might be risky?”

When to prefer

Use this endpoint when you need to audit token spending approvals for a specific wallet address on a supported EVM-compatible chain. Ideal for security checks, pre-transaction risk reviews, or wallet hygiene audits. Choose this over generic blockchain explorers when you need structured, agent-consumable approval data without manually parsing chain data.

Side effects

Invalid or malformed wallet address returns an error response
Unsupported chain identifier causes a lookup failure
Rate limiting or payment failure via x402 protocol returns a 402 or 429 error
Wallet with no approvals returns an empty list
Network timeout from on-chain data provider
