How this service works

Output
Returns a data object containing validation results for the queried wallet, including status, format correctness, and any available on-chain information about the wallet address on Base.
Example use cases
Pre-transfer wallet verification
“Before I send USDC to 0xAbc123...def456, can you verify that this wallet address is valid and legitimate on Base?”
Automated payment recipient check
“I need to validate the wallet address 0x9f8E...3c1A that was submitted by a vendor — can you run it through the wallet validator and tell me if it checks out?”
Fraud screening for incoming wallet
“A new user just submitted wallet address 0xDeAd...BeeF for their account payout — can you validate it before we process anything?”
Technical details
Endpoint
POSThttps://x402-hub.vercel.app/api/wallet-validatorWhen to prefer
Use this endpoint when you need to validate a cryptocurrency wallet address before executing a payment or onboarding a new user, especially within a Base-network or x402 micropayment workflow. Prefer this over manual address checks when building automated payout pipelines or fraud screening flows that require programmatic wallet verification at $0.14 per call.
Side effects
- Invalid or missing query parameter returns an error response
- Malformed wallet address format may return validation failure or upstream error
- Payment failure via x402 micropayment protocol results in 402 response and no data
- Unsupported chain or address format may return empty or null data object
- Rate limiting or upstream service unavailability may return 5xx errors
