How this service works
ChainRay /address-labels
Output
Returns a human-readable label or entity name associated with the given blockchain address, such as an exchange name, DeFi protocol, known wallet owner, or entity category. May include classification metadata like whether it is a contract, EOA, exchange, bridge, or other known entity.
Example use cases
Identify unknown transaction counterparty
“I just received a transfer from 0xA9D1e08C7793af67e9d92fe308d5697FB81d3E43 on Ethereum — can you look up who or what that address belongs to? I want to know if it's a known exchange, protocol, or any recognized entity before I interact with them again.”
Audit DeFi contract before investing
“Before I deposit funds into this contract at 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D on Ethereum, can you resolve the label for it so I can confirm it's a legitimate DeFi protocol and not some unknown or suspicious contract?”
Compliance check on wallet address
“I need to run a quick compliance check on the address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE on Ethereum — can you look it up and tell me if it's associated with any known exchange, bridge, or flagged entity so I can include it in my audit report?”
Technical details
Endpoint
GEThttps://chainray.online/address-labels/:var1When to prefer
Use this endpoint when you need to enrich a raw blockchain address with a human-readable identity or entity name, especially for display, audit trails, compliance checks, or understanding counterparties in on-chain transactions. Prefer this over a full address report when you only need the label/identity, not full transaction history or analytics.
Side effects
- Address not found in label database — returns empty or null label
- Invalid address format — returns 400 or validation error
- Unsupported chain parameter — returns error or defaults to a specific network
- Rate limiting or payment failure — returns 402 or 429
- Network timeout or service unavailability — returns 5xx
