ChainRay Cross-Chain Address Lookup
x402
ChainRay Cross-Chain Address Lookup is a paid API for AI agents from chainray.online, paid per call via x402, $0.02/call, not verified (last probed 2026-10-29); live alternatives: Codex GraphQL API ($0.001) and AgenticFi Block Height Lookup ($0.001).
Agents call it through Zero, which pays per call: no API key and no wallet of your own. New accounts start with $5. Live alternatives for the same use case: Codex GraphQL API ($0.001) · AgenticFi Block Height Lookup ($0.001).

How this service works
Blockchain data and intelligence service for AI agents. 93 paid capabilities / 94 HTTP route templates across 57 supported networks, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.
Output
On-chain intelligence data for the specified address including activity, balances, DeFi positions, and other analytics aggregated across multiple blockchain networks (up to 46 chains supported).
Example use cases
Monitor whale wallet activity across chains
“I need to keep tabs on this whale address 0x742d35Cc6634C0532925a3b8D4C9C6A3 — can you check what they're doing across all the chains they're active on? I want to know their balances and recent moves.”
Audit DeFi positions before investing
“Before I invest in this protocol, can you pull all the on-chain intelligence for address 0x742d35Cc6634C0532925a3b8D4C9C6A3? I need to see their DeFi positions across every chain they use.”
Verify contract legitimacy across networks
“I found this contract address 0x742d35Cc6634C0532925a3b8D4C9C6A3 and want to make sure it's legit — can you get me the complete cross-chain data and activity history across all 46 networks?”
Technical details
Endpoint
GEThttps://chainray.online/cross-chain/%7Baddress%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need unified cross-chain intelligence for a specific wallet or contract address and want to avoid querying multiple chain-specific APIs. Best suited for multi-chain portfolio views, DeFi analytics, and on-chain due diligence across up to 46 chains in a single request.
Side effects
- Invalid or malformed wallet/contract address returns an error
- Unsupported chain identifier returns an error or empty result
- Address not found on specified chain returns empty data
- Rate limiting or payment failure returns 402 Payment Required
- Network timeout for chains with slow RPC response
