概述

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.

简而言之

• 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

身份验证

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"

提示

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	描述	文档
核心 API	Interact with RPC, REST, and gRPC endpoints across all supported blockchains	查看
Streams API	Create and manage real-time blockchain data pipelines	查看
Webhooks API	Configure event-driven notifications for onchain activity	查看
SQL Explorer API	Run SQL queries against indexed onchain data via REST	查看
Key-Value Store API	Read and write to serverless key-value storage	查看
管理 API	Programmatically manage endpoints, usage, security, and billing — or do it conversationally through Quicknode MCP	查看
IPFS API	Pin and retrieve files on IPFS through the Quicknode gateway	查看

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.

API	Spec URL
Streams API	api.quicknode.com/streams/rest/openapi.json
Webhooks API	api.quicknode.com/webhooks/rest/openapi.json
Key-Value Store API	api.quicknode.com/kv/rest/openapi.json
IPFS API	quicknode.com/docs/openapi/ipfs.openapi.json
管理 API	quicknode.com/docs/openapi/admin-api.openapi.json

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.
