How this service works
Which chain does this address belong to, and is it well-formed — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object indicating whether the address is valid (ok), the identified chain type, a receipt with transaction hash, USD amount charged, and receipt ID, and a generated_at timestamp.
Example use cases
Unknown address chain detection
“I received this address from someone and I'm not sure if it's Bitcoin, Ethereum, or something else — can you tell me which chain it belongs to and if it's properly formatted: bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq?”
Pre-transfer address sanity check
“Before I send funds, can you verify that this address is well-formed and tell me what network it's on: 0x742d35Cc6634C0532925a3b844Bc454e4438f44e?”
Wallet address validation in onboarding
“A user just entered this withdrawal address in our app — is it a valid, well-formed address and which blockchain does it belong to: 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy?”
Technical details
Endpoint
POSThttps://twin.unykorn.org/address-identify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have an unknown or user-supplied address string and need to determine both its blockchain network and format validity in a single call, especially in a multi-chain context where the user has not specified the network. Prefer this over chain-specific validators when the chain is unknown upfront.
Side effects
- Malformed or empty address string returns an error or ok:false
- Ambiguous address strings that match no known chain format return unrecognized type
- Service unavailability returns HTTP 5xx
- Payment failure (x402 protocol) prevents request from being processed
- Addresses on unsupported or obscure chains may not be identified
