Technical details
Endpoint
GEThttps://lanescrypt.vercel.app/api/approvals/%7Bchain%7D/%7Baddress%7DWhen to prefer
Use this endpoint when you need to audit token approvals for a specific wallet address on a supported blockchain — particularly useful for DeFi security checks, identifying risky unlimited approvals, or building wallet analytics dashboards. Prefer this over generic blockchain explorers when you need structured, programmatic approval data payable per-call via USDC.
Side effects
- Invalid or malformed wallet address returns error
- Unsupported chain identifier returns 4xx error
- No approvals found returns empty result set
- Payment failure via x402 returns 402 response
- Rate limiting may return 429 if quota exceeded
