How this service works
The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.
Output
A human-readable label and classification metadata for the queried blockchain address, including entity name, address type (exchange, protocol, EOA, multisig, etc.), and any associated tags or annotations for the specified chain.
Example use cases
Example prompt
“What's the label for the address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum — is it a known exchange, protocol, or whale wallet?”
Technical details
Endpoint
GEThttps://chainray.online/address-labels/%7Baddress%7DWhen to prefer
Use this endpoint when you need to identify or annotate a specific blockchain address with a human-readable label — for example, enriching transaction data, flagging known exchanges, or resolving contract addresses to protocol names. Prefer it over on-chain ENS/domain lookups when you need cross-chain coverage (46 chains) and curated intelligence labels beyond just domain names.
Side effects
- Unknown address — no label found, returns empty or null result
- Invalid address format — malformed hex string returns 400 error
- Unsupported chain — chain parameter not recognized returns 400 or 404
- Payment failure — x402 payment not accepted, returns 402
- Rate limiting or quota exceeded — returns 429
