Example use cases
Pre-transfer address verification
“Before I send 500 USDC, can you verify that this Ethereum wallet address is valid and correctly formatted: 0x4Bd5643ac6f66a5237E18bfA7d47cF22f1c9F210?”
Payment form validation for crypto checkout
“A user just entered this wallet address in my crypto checkout form — can you check if it's a valid Bitcoin address before I let them proceed? The address is 1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf Na.”
Bulk wallet sanity check before airdrop
“I'm about to do an airdrop and I need to make sure this recipient address is valid on the Ethereum network before adding it to my list: 0x000000000000000000000000000000000000dEaD — is it legitimate?”
Technical details
Endpoint
POSThttps://kite-endpoints.vercel.app/api/crypto-wallet-address-validator1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-use wallet address validation without integrating a full blockchain SDK. Ideal for agents handling payment flows, onboarding forms, or airdrop pipelines that need a lightweight sanity check on user-supplied addresses before committing funds or storing the address.
Side effects
- Malformed or missing address input returns an error or invalid flag
- Unsupported blockchain network may yield indeterminate results
- Ambiguous address format (e.g. checksummed vs non-checksummed) may not be distinguished
- Service outage or upstream provider failure returns a 500 error
- Incorrect network specified for the address causes false negative validation
