Read the announcementConnect to Flow mainnet and Testnet with low-latency RPC, full archive data, debug and trace APIs, and real-time Streams. The complete Flow data stack, managed from a single Quicknode dashboard.
SOC 2 Type II Certified · ISO 27001
Flow builders need more than basic RPC. Quicknode runs the full surface: the Flow REST API, the gRPC Access API, and the Flow EVM JSON-RPC, all from one dashboard.
Query and read across Cadence and Flow EVM with low latency. From a single Access API call to Solidity contracts, you get the right interface for the job.
Six ways to access Flow data, from a single Cadence script to Flow EVM contracts and real-time Streams. Pick the interface, ship faster.
Query accounts, blocks, transactions, and events over the HTTP-based Flow REST API on mainnet and testnet.
Point FCL at a Quicknode Flow endpoint to run Cadence scripts and read accounts, or point ethers.js and viem at the Flow EVM JSON-RPC. The Flow Access API, REST, and Flow EVM on private low-latency infrastructure.
Point FCL or the Flow CLI at a Quicknode Flow endpoint, or use Ethereum tools against Flow EVM. Scripts, queries, and contracts carry over.
The Flow REST and gRPC Access API for Cadence, plus the Flow EVM JSON-RPC for Solidity, on one endpoint.
Docs, guides, and runnable sample apps for every Flow workload. Clone, customize, and ship.
Full reference for the Flow REST API, the gRPC Access API, and the Flow EVM JSON-RPC, with Cadence and Solidity examples.
Set up backfill and real-time Flow data delivered to your own datastore and API with Quicknode Streams.
From your first Flow endpoint to mission-critical production workloads, Quicknode scales with you. Get started in minutes.
Spin up your Flow endpoint and ship. The free tier covers prototyping and small production loads, no credit card required.

Frequently Asked Questions
Still have unanswered questions? Reach out to support and the Quicknode team can help you find answers.
The Flow toolchain you already know works unchanged on Quicknode. FCL (@onflow/fcl), the Flow CLI, and Ethereum tools for Flow EVM all point at a Quicknode endpoint.
Backfill and real-time Flow data delivered to your datastore with guaranteed reliability.
Event-driven alerts with guaranteed delivery. Subscribe to specific addresses, event types, or onchain conditions.
High-performance gRPC access to the Flow Access API for accounts, scripts, and event streaming.
Ethereum-compatible JSON-RPC (Beta) for Flow EVM, so Solidity contracts and eth_ methods run on Flow.
Execute Cadence scripts and read resource-oriented contract state through the Access API.
// Query Flow with FCLimport * as fcl from "@onflow/fcl";fcl.config().put("accessNode.api", QUICKNODE_FLOW_URL);const latest = await fcl.block({ sealed: true });console.log(latest.height);// Flow REST, gRPC Access API, and Flow EVM on one endpoint.
Runnable sample apps and starter kits across Quicknode-supported chains, including Flow. Clone one and ship.
"Quicknode Streams is a promising technology for allowing both new and existing builders to have significantly better blockchain processing pipelines. After successful proof of concepts on limited use cases, we are looking to expand Streams across our entire stack for core functionalities, like balance, transaction history, and more."Andrei Terentiev, CTO @ Bitcoin.com
