How to index Kusama blockchain data

Stream Kusama transactions and blocks from the SQD Portal in two lines of code. The example below uses the public endpoint, no API key required for development.

1curl --compressed -X POST \

Frequently asked questions

How do I index Kusama blockchain data?

Use the SQD Portal API at portal.sqd.dev/datasets/kusama or the open-source Squid SDK. Both stream Kusama blocks, transactions, and onchain events from historical archives. The free tier supports development; paid Portal deployments cover production workloads with SLA-backed latency.

Is the Kusama API free?

Yes. SQD provides a free public Portal endpoint for Kusama with no API key required. For higher rate limits, dedicated infrastructure, and SLA-backed uptime, see the SQD Pricing page.

What Kusama data tables does SQD provide?

SQD indexes the standard set of Kusama data including blocks, transactions, and onchain events. All data is decoded and validated at ingestion.

Does SQD support real-time Kusama data?

Kusama historical and recent data is available through SQD's archival layer. Real-time streaming for Kusama is on the roadmap, request priority via the SQD contact form.

What's the difference between SQD and an RPC node for Kusama?

An RPC node serves raw, unvalidated Kusama data limited to recent state. SQD's Portal indexes the full Kusama history, decodes it into queryable tables, validates every block at ingestion, and serves it through a typed SDK, no node operations required.

Can I self-host Kusama indexing with SQD?

Yes, the Squid SDK is open-source under the GPLv3 license. You can run your own indexer against the SQD Network or the Portal, or deploy on SQD Cloud for fully managed hosting.
