Kaspa keeps attracting builders because of its blockDAG design and one-second block times, and that speed only shows up in a product if the RPC layer behind it keeps pace. Anyone shipping a wallet, exchange integration, or explorer on top of Kaspa eventually runs into the same fork in the road: maintain a full node yourself, with all the syncing and monitoring that entails, or hand that job to a provider and spend the saved time on the actual product. The five options below cover that second path, from full-service infrastructure companies to the community-run public network Kaspa itself points newcomers toward.
NOWNodes runs infrastructure across more than 120 blockchains, and Kaspa sits alongside the rest under the same account and the same API key. A shared full node pools requests across NOWNodes' own cluster, so a project can be live within minutes of signing up, and a dedicated node is available for teams that want isolated capacity for their kaspa nodes traffic once volume grows. What stands out in practice is the absence of throttling: unlimited RPS on all paid plans, no rate limits, so a spike in on-chain activity doesn't translate into dropped requests or a support ticket. Wallets like Tangem, Trust Wallet, and Exodus, along with the payment platform CoinGate, already run their infrastructure through NOWNodes, which says something about how the setup holds up under real production load rather than just benchmark traffic.
Key features:
Why choose NOWNodes: the pitch here isn't a single strength but the combination — a provider that already tracks blockchain activity around the clock and rolls out node updates across its fleet within hours means a project rarely finds itself running against a stale or deprecated RPC version. Getting started is a matter of generating an API key from a profile page and pointing requests at the documented Kaspa endpoints, with no separate procurement process for the Kaspa network specifically.
Ideal for: teams already running other chains through NOWNodes who want Kaspa folded into the same billing and dashboard, and for wallets or exchanges that need dedicated capacity without operating their own node.
Forbole is a Hong Kong-based infrastructure provider with a straightforward tiered structure: a free plan capped at 250,000 requests and 10 requests per second, and paid plans starting around $20 a month that raise the ceiling to 1,000 requests per second along with a much larger request allowance. Access comes in REST, gRPC, and RPC form, with WebSockets added once a project moves off the free tier, and dedicated or archive nodes become available on the higher-tier plans for teams that need isolated or full-history access.
Key features:
Why choose Forbole: the free tier is generous enough to prototype against before any money changes hands, and support runs through Discord on the entry plans and Telegram once a project pays for a plan, which keeps the escalation path simple.
Ideal for: smaller projects, hackathon builds, or teams that want to validate an integration against Kaspa mainnet before signing a longer commercial agreement.
Kas.fyi is better known as a Kaspa block explorer, and the Kaspa Developer Platform is the API arm built by the same team. It works as a hosted layer over chain data — address history, transaction acceptance checks, block ranges by blue score or DAA score, mempool reads, and a proxy for raw node RPC calls — plus mining endpoints such as getBlockTemplate and submitBlock for anyone running mining infrastructure. It also exposes KRC20 token metadata and market data, which the general-purpose providers on this list don't cover natively.
Key features:
Why choose Kas.fyi: a team already using the explorer for manual lookups gets the same data programmatically, and the mining endpoints fill a gap most generic RPC providers leave out entirely.
Ideal for: dashboards and analytics tools that need a second data source alongside a primary node, and teams working with KRC20 tokens specifically.
Crypto APIs takes a different angle: instead of exposing raw JSON-RPC as the default, it wraps Kaspa data — transactions, addresses, balances, UTXOs, and block data — behind a single REST endpoint, with webhooks that push incoming and outgoing transaction events and confirmations as they happen. Teams that specifically want JSON-RPC can still get it through the company's separate Node as a Service and Dedicated Nodes products, so the raw-access path exists without being the main one.
Key features:
Why choose Crypto APIs: a product that already treats Kaspa as one asset among the dozens Crypto APIs supports — Bitcoin, Ethereum, Litecoin, Dogecoin, and others — can integrate Kaspa without learning a chain-specific RPC surface.
Ideal for: multi-currency wallets, exchanges, and custody products where Kaspa is one line item in a broader roadmap rather than the sole focus.
Kaspa's own developer docs point newcomers toward the Public Node Network, a decentralized pool of community-operated nodes reachable through the Kaspa Resolver and the official WASM SDK bindings, directly from a browser with no account or API key involved. It's genuinely free and works for reading DAG state, subscribing to block-added or DAA-score events, and monitoring addresses for UTXO changes. The documentation itself is candid that this path can take a few seconds to initialize and isn't meant for large-scale production traffic, which is a fair trade for something that costs nothing and requires no setup.
Key features:
Why choose the Public Node Network: it's the fastest way to get a first RPC call working while evaluating whether Kaspa fits a project at all, before any provider conversation starts.
Ideal for: prototyping, learning the RPC surface, and small scripts or research projects that don't need production guarantees.
On the product side, NOWNodes organizes Kaspa access around two node types — Shared and Dedicated — both scoped to Kaspa Mainnet, which covers how a project chooses between pooled infrastructure and a private node before writing a single line of code. Underneath that choice sits a full REST API reference covering the practical surface a Kaspa integration needs day to day:
That range means a wallet, explorer, or exchange can pull everything from a raw address balance to network-wide hashrate and coin supply through the same API key, without stitching together a second data source for the numbers that sit outside strict RPC calls, like price or market cap.
