Onchain Data Explorer

Onchain Data Explorer is built and maintained by the OKX Blockchain Explorer team. It provides an API service for read-only blockchain data across 180+ chains spanning all major ecosystems, helping users query and analyze on-chain information — including activities, transactions, addresses, tokens, contracts, market data, and broader insights. All x402 endpoints use HTTP POST; an unpaid POST returns a 402 payment-required challenge (GET returns 405).
