Quicknode APIs

更新日：
Jul 02, 2026

概要​

Quicknode exposes its full product suite through standard HTTP, JSON-RPC, REST, gRPC, and WebSocket endpoints. These are the same APIs that power production dApps and infrastructure. Because they use standard protocols, any application, AI agent, or LLM-powered tool can call them directly without special SDKs or wrappers.


要約
  • Core API, Streams, Webhooks, Key-Value Store, and Admin API are all standard HTTP/JSON-RPC/REST/gRPC/WebSocket endpoints, no special SDK needed
  • API keys authenticate account-based access. Get one via the Quicknode dashboard or programmatically through Agent Subscriptions
  • For accountless access, wallet-based per-request access with no signup is available for Core API endpoints, use x402 or MPP payments

認証​

Quicknode APIs authenticate with an API key tied to your account. You can generate and manage API keys from the Quicknode dashboard or programmatically through Agent Subscriptions.

All requests include the API key either as part of the endpoint URL or as a header, depending on the API:

# JSON-RPC — API key is part of the endpoint URL
curl https://your-endpoint-name.network-name.quiknode.pro/your-api-key/ \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{"method":"eth_blockNumber","params":[],"id":1,"jsonrpc":"2.0"}'

# REST API — API key as a header
curl https://api.quicknode.com/streams \
  -H "x-api-key: YOUR_API_KEY"

ヒント

If you prefer wallet-authenticated, pay-per-request access with no account required, see x402 Payments or MPP Payments.

Supported Protocols​

Quicknode endpoints support multiple protocols depending on the chain and product:

  • JSON-RPC — Standard RPC calls over HTTP for all supported chains
  • REST — RESTful endpoints for Streams, Webhooks, Key-Value Store, and Admin APIs
  • gRPC — High-throughput streaming for Solana gRPC (Yellowstone-compatible Geyser gRPC) and Hyperliquid (Hypercore)
  • WebSocket — Real-time subscriptions for event-driven workflows

Available APIs​

API説明ドキュメント
コアAPIInteract with RPC, REST, and gRPC endpoints across all supported blockchains表示
Streams APICreate and manage real-time blockchain data pipelines表示
Webhooks APIConfigure event-driven notifications for onchain activity表示
SQL Explorer APIRun SQL queries against indexed onchain data via REST表示
Key-Value Store APIRead and write to serverless key-value storage表示
管理用APIProgrammatically manage endpoints, usage, security, and billing — or do it conversationally through Quicknode MCP表示
IPFS APIPin and retrieve files on IPFS through the Quicknode gateway表示

Each API has full documentation with method references, parameters, and ready-to-run examples. Point your agent at the docs index or install Blockchain Skills to give it accurate knowledge of these APIs out of the box.

Quicknode SDK​

Manage your whole Quicknode setup from code. The Quicknode SDK gives you typed clients for the Admin, Streams, Webhooks, and Key-Value Store APIs in Rust, Python, Node.js, and Ruby, so you can create and configure endpoints, set security rules, handle billing, manage teams, run Streams and Webhooks, and read or write the Key-Value Store, all as native method calls. It handles authentication, request and response types, and pagination for you, so the requests come out correct with fewer runtime errors than hand-rolled calls.

API Specifications (OpenRPC, OpenAPI)​

Quicknode publishes machine-readable OpenAPI and OpenRPC specs for its APIs. Agents can load them to auto-generate request shapes, validate parameters, and discover available operations without scraping the docs.

For the Core API, Quicknode publishes per-chain OpenRPC/OpenAPI specs covering RPC methods. Coverage is rolling out across major chains; see the Ethereum API Overview for a representative example, and the linked spec is available alongside each chain's API overview page.
