コアAPI
Quicknodeの主力ブロックチェーンRPC API。世界中に分散したエッジエンドポイントから、80以上のチェーンと130以上のネットワークへ、50ms未満のレイテンシ、アーカイブデータ、WebSockets、および99.99%の稼働率を保証するSLAを備えた、本番環境レベルのアクセスを提供します。
概要
Core API is Quicknode's flagship blockchain RPC product, giving developers fast, reliable, and highly available access to 80+ blockchains and 130+ networks (mainnets and testnets) through a single, consistent JSON-RPC, REST, and WebSocket interface. It is the foundation that powers exchanges, wallets, DeFi protocols, indexers, RPC re-providers, and AI agents across Ethereum, Solana, Hyperliquid, Base, BNB Smart Chain, Polygon, Arbitrum, Optimism, Avalanche, TRON, Monad, Sui and many more.
Core API is delivered from Quicknode's globally distributed edge network with POPs across North America, Europe, and APAC, which keeps median RPC latency under 50ms for most clients and avoids the cold-start and rate-limit problems of public endpoints. Every Core API endpoint includes built-in load balancing, automatic failover across redundant nodes, full archival data on supported chains, WebSocket subscriptions, and MEV-protected transaction submission where applicable.
Core API is enterprise-ready out of the box: SOC 2 Type II certified, ISO 27001 certified, with a 99.99% uptime SLA available, signed DPAs and EU data residency options for GDPR-regulated workloads, and dedicated support for production teams. It pairs natively with the rest of the Quicknode platform, including Streams for real-time pipelines, Webhooks for event alerts, IPFS for storage, Clusters for dedicated backends, SQL Explorer for onchain queries, and the Marketplace for one-click add-ons.
Trusted by over 1 million developers and most of the largest names in Web3, Core API offers a free tier with no credit card required so developers can prototype immediately and scale in place to dedicated nodes and enterprise plans without changing endpoint URLs or rewriting code.
問題点
Running and scaling your own blockchain nodes is expensive, slow, and unreliable. Public RPC endpoints rate-limit aggressively and lack archival data, while building production-grade multi-chain infrastructure in-house requires a dedicated team that most developers don't want or can't afford.
