Multi-chain data availability (SQD)

Query raw and decoded on-chain blockchain data across 113+ networks through the buy gateway at https://gateway.usebuy.ai/sqd.

The gateway proxies requests to the decentralized SQD Network (formerly Subsquid) Portal, providing high-throughput historical and real-time data access without requiring node infrastructure, archive nodes, or chain-specific RPC providers.

Unlike the paid API capabilities under /v1/, the /sqd/ endpoints are completely free — no x402 payment challenge, no signing, and no tokens required.
