Frequently asked questions
Is Kwery free?
Yes. The Free plan is $0 with 1M API credits per month. Developer is $12/mo (10M credits, webhooks, enhanced APIs). Business is $49/mo (50M credits, higher limits). Paid plans include $2 per million overage credits.
What networks are supported?
Kwery targets Kaspa mainnet and testnet. Network selection is configured per API key or endpoint path as the platform rolls out.
How is this different from running my own node?
You get managed RPC endpoints, API key auth, rate limiting, usage analytics, and enhanced developer APIs without operating Kaspa node infrastructure yourself.
What RPC methods are available?
Standard Kaspa JSON-RPC methods including getBlock, getBlocks, getUtxosByAddresses, getBalanceByAddress, submitTransaction, and more. See the docs for the full method list as endpoints go live.
How do I authenticate?
Pass your API key via the X-API-Key header on RPC and REST requests. Keys are created in the dashboard.
