Quicknode Blockchain Infrastructure

Intake Questions

• Which chain and network should Quicknode target?
• Is this read-only or should I create infrastructure (streams, webhooks, IPFS writes)?
• Does this require real-time streaming (gRPC/Yellowstone/Hypercore) or standard RPC?
• What endpoint or API key should I use (default: QUICKNODE_RPC_URL, optional QUICKNODE_WSS_URL / QUICKNODE_API_KEY)?
• If no API key exists, does the agent want pay-per-request access (x402, MPP) or a wallet-paid Quicknode account via Agent Subscriptions?
• Any constraints (latency, regions, throughput, destinations)?

Safety Defaults

• Default to testnet/devnet when a network is not specified.
• Prefer read-only operations and dry runs before creating resources.
• Never ask for or accept private keys or secret keys.

Confirm Before Write

• Require explicit confirmation before creating or modifying Streams, Webhooks, or IPFS uploads.
• Require explicit confirmation before creating an Agent Subscription, topping up credits, or any action that spends real funds via x402 or MPP.
• If confirmation is missing, return the exact API payload for review.

const nfts = await core.client.qn_fetchNFTs({
  wallet: '0x...',
  page: 1,
  perPage: 10,
});

See references/sdk-reference.md for complete SDK documentation.

Admin API

REST API for programmatic management of Quicknode endpoints, usage, rate limits, security, billing, and teams. Enables infrastructure-as-code workflows.

Quick Reference

| Resource | Methods | Endpoint | |----------|---------|----------| | Chains | GET | /v0/chains | | Endpoints | GET, POST, PATCH, DELETE | /v0/endpoints | | Metrics | GET | /v0/endpoints/{id}/metrics | | Rate Limits | GET, POST, PUT | /v0/endpoints/{id}/method-rate-limits, /v0/endpoints/{id}/rate-limits | | Security | GET | /v0/endpoints/{id}/security_options | | Usage | GET | /v0/usage/rpc, by-endpoint, by-method, by-chain | | Billing | GET | /v0/billing/invoices | | Teams | GET | /v0/teams |

Authentication

All requests use the x-api-key header against https://api.quicknode.com/v0/.

const QN_API_KEY = process.env.QUICKNODE_API_KEY!;

const res = await fetch('https://api.quicknode.com/v0/endpoints', {
  headers: { 'x-api-key': QN_API_KEY },
});
const endpoints = await res.json();

See references/admin-api-reference.md for full Admin API documentation including endpoint CRUD, usage monitoring, rate limit configuration, security options, billing, and teams.

Key-Value Store (Beta)

Serverless storage for lists and key-value sets, primarily accessed from within Streams filter functions via the qnLib helper library. Also available via REST API.

Stream Integration (qnLib)

List operations — manage lists of items (e.g., wallet addresses):

• qnLib.qnUpsertList — create or update a list
• qnLib.qnAddListItem — add item to a list
• qnLib.qnRemoveListItem — remove item from a list
• qnLib.qnContainsListItems — batch membership check
• qnLib.qnDeleteList — delete a list

Set operations — manage key-value pairs:

• qnLib.qnAddSet — create a key-value set
• qnLib.qnGetSet — retrieve value by key
• qnLib.qnBulkSets — bulk create/remove sets
• qnLib.qnDeleteSet — delete a set

Docs: https://www.quicknode.com/docs/key-value-store

x402 (Pay-Per-Request RPC)

Pay-per-request RPC access via stablecoin payments. No API key required. Two access patterns: pay-per-request ($0.001/call, no auth needed) and credit drawdown (SIWX auth, $10/1M requests). Supports USDC on Base/Polygon/Solana and USDG on XLayer. Access 140+ chain endpoints.

Quick Setup

import { wrapFetch } from "@x402/fetch";
import { createWalletClient, http } from "viem";
import { privateKeyToAccount } from "viem/accounts";
import { base } from "viem/chains";

const account = privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`);
const walletClient = createWalletClient({
  account,
  chain: base,
  transport: http(),
});

// Wrap fetch to auto-handle 402 payments
const x402Fetch = wrapFetch(fetch, walletClient);

// Use like normal fetch — payments are handled automatically
const response = await x402Fetch("https://x402.quicknode.com/ethereum-mainnet", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    jsonrpc: "2.0",
    method: "eth_blockNumber",
    params: [],
    id: 1,
  }),
});

See references/x402-reference.md for complete x402 documentation including SIWE authentication, credit management, and the @x402/fetch wrapper.

MPP (Machine Payments Protocol)

Pay-per-request RPC access via IETF Payment Authentication headers. No API key required. Two intent types: charge ($0.001/request) and session ($0.00001/request via off-chain vouchers). Payment via PathUSD or USDC.e on Tempo mainnet, PathUSD on Tempo testnet, or USDC on Solana. Access 140+ chain endpoints.

Quick Setup

import { Mppx, tempo } from 'mppx/client'
import { privateKeyToAccount } from 'viem/accounts'

const account = privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`)

// Polyfills globalThis.fetch — handles 402 challenges automatically
Mppx.create({
  methods: [tempo({ account })],
})

// Charge intent ($0.001/req) — payment is transparent
const response = await fetch('https://mpp.quicknode.com/tempo-mainnet', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    jsonrpc: '2.0',
    id: 1,
    method: 'eth_blockNumber',
    params: [],
  }),
})

const { result } = await response.json()
console.log('Block number:', BigInt(result))

See references/mpp-reference.md for complete MPP documentation including charge vs session intents, Solana setup, CLI usage, and payment receipts.

Agent Subscriptions

Programmatic Quicknode account creation for autonomous agents. A single POST to /api/v1/agent/subscriptions with an x402 or MPP payment creates a paid account synchronously and returns a QN_* full platform API key, no dashboard signup or email confirmation required. The same payment SDKs used for x402 and MPP per-request RPC sign the subscription payment.

Docs: https://www.quicknode.com/docs/build-with-ai/agent-subscriptions

When to Use

• Pay-per-request (x402, MPP) when the agent only needs short-lived RPC access with no persistent state.
• Agent Subscriptions when the agent needs the full platform: Streams, Webhooks, Key-Value Store, multiple endpoints, security rules, billing, or any other Admin API surface.

Discover Plans

To fetch the live plan list, prices, accepted payment networks, asset contract addresses, and recipient (payTo) addresses, send the request without a payment header. The server returns HTTP 402 with the details in the body and a PAYMENT-REQUIRED header (base64-encoded x402 requirement).

curl -X POST https://www.quicknode.com/api/v1/agent/subscriptions \
  -H "Content-Type: application/json" \
  -d '{}'

Parse the 402 body, pick a plan, then retry the request through the SDK.

Quick Setup (x402)

import { createQuicknodeX402Client } from '@quicknode/x402'

const client = await createQuicknodeX402Client({
  baseUrl: 'https://www.quicknode.com',
  network: 'eip155:8453', // Base Mainnet
  evmPrivateKey: process.env.PRIVATE_KEY as `0x${string}`,
})

const res = await client.fetch(
  'https://www.quicknode.com/api/v1/agent/subscriptions',
  {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      plan_name: 'b6_build', // b6_build | b6_accelerate | b6_scale | b6_business
      interval: 'monthly', // monthly | yearly
      email: '[email protected]',
      password: process.env.ACCOUNT_PASSWORD,
      password_confirmation: process.env.ACCOUNT_PASSWORD,
      full_name: 'Autonomous Agent',
      name: 'Agent Account',
      billing_address: {
        line1: '123 Main St',
        city: 'New York',
        postal_code: '10001',
        country: 'US',
      },
    }),
  },
)

const { api_key } = await res.json() // "QN_..." full platform API key

The returned api_key is the same QUICKNODE_API_KEY used everywhere else in this skill. Use it against https://api.quicknode.com/v0/... to provision endpoints, configure security, top up credits, read balances, and so on.

Paying with Solana? Use @quicknode/x402-solana to sign x402 payments with a Solana keypair instead of an EVM private key. Once configured, the subscription request body and Admin API steps are identical to the x402 example above. See the How to Access Solana RPC with x402 guide for setup details.

Quick Setup (MPP)

import { Mppx, tempo } from 'mppx/client'
import { privateKeyToAccount } from 'viem/accounts'

const account = privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`)

// Activate MPP. Polyfills globalThis.fetch so 402 challenges are
// intercepted, signed, and retried automatically inside fetch.
Mppx.create({ methods: [tempo({ account })] })

const subscriptionRes = await fetch(
  'https://www.quicknode.com/api/v1/agent/subscriptions',
  {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      plan_name: 'b6_build', // b6_build | b6_accelerate | b6_scale | b6_business
      interval: 'monthly', // monthly | yearly
      email: '[email protected]',
      password: process.env.ACCOUNT_PASSWORD,
      password_confirmation: process.env.ACCOUNT_PASSWORD,
      full_name: 'Autonomous Agent',
      name: 'Agent Account',
      billing_address: {
        line1: '123 Main St',
        city: 'New York',
        postal_code: '10001',
        country: 'US',
      },
    }),
  },
)

const { api_key } = await subscriptionRes.json() // "QN_..." full platform API key

Endpoints

| Method | Path | Auth | Rate limit | Purpose | |--------|------|------|------------|---------| | POST | /api/v1/agent/subscriptions | Payment header (x402 or MPP) | 30/min | Create account and subscription | | POST | /api/v1/agent/top_up | API key + payment header | 30/min | Add credits to an existing subscription | | GET | /api/v1/agent/balance | API key | 60/min | Read current credit balance |

All requests target https://www.quicknode.com.

Plan IDs

b6_build, b6_accelerate, b6_scale, b6_business. Map directly to the public Build / Accelerate / Scale / Business plans on pricing. Use the discovery 402 above when the agent needs to choose a plan dynamically.

Guard Rails

• Real funds: Subscriptions settle in real stablecoins on a mainnet payment network. Confirm plan, interval, and payment network with the user before sending the request.
• Duplicate email protection: Re-using an existing email returns an error. Resume failed requests with the same email and password instead of creating a duplicate account.
• No free trials: All subscriptions are production-grade from the first request.
• Synchronous creation: Account creation and subscription activation happen in the same request. There is no async job or webhook to wait for.
• No invented details: Never fabricate billing details, passwords, or email addresses. Require explicit user input. Password must be 8–64 characters with at least one lowercase letter, one uppercase letter, one number, and one special character.

Common Patterns

Multi-Chain dApp Setup

import { Core } from '@quicknode/sdk';

const chains = {
  ethereum: new Core({
    endpointUrl: 'https://YOUR_ETH_ENDPOINT.quiknode.pro/KEY/'
  }),
  polygon: new Core({
    endpointUrl: 'https://YOUR_POLYGON_ENDPOINT.quiknode.pro/KEY/'
  }),
  arbitrum: new Core({
    endpointUrl: 'https://YOUR_ARB_ENDPOINT.quiknode.pro/KEY/'
  }),
};

// Use appropriate chain
const ethBalance = await chains.ethereum.client.getBalance({ address: '0x...' });

Real-Time Transaction Monitoring

1. Create Stream filtering for your contract address
2. Add Filter Function to extract relevant events
3. Configure Webhook destination to your server
4. Process Events in your backend

NFT Collection Indexing

1. Use Streams to capture mint/transfer events
2. Store in Database via PostgreSQL destination
3. Query via Add-ons for current ownership data
4. Query via SDK for custom API endpoints

Real-Time Solana Monitoring with Yellowstone gRPC

1. Connect via gRPC on port 10000 with your auth token
2. Subscribe to transactions filtering by program or account
3. Process updates in real-time via the streaming interface
4. Implement reconnection with exponential backoff

Hyperliquid Trading Data Pipeline

1. Connect via gRPC on port 10000 for lowest-latency data
2. Subscribe to TRADES/ORDERS streams with coin filters
3. Process events — handle ~12 blocks/sec throughput
4. Use Info API (/info) for account state and market metadata

Historical Trading Analysis with SQL Explorer

1. Query historical trades — SELECT * FROM hyperliquid_trades WHERE block_time > ...
2. Aggregate metrics — Use GROUP BY for volume, counts, averages
3. Join tables — Combine trades, orders, funding for comprehensive analysis
4. Export data — Results as JSON for downstream processing

Best Practices

RPC

• Use WebSocket for subscriptions and real-time data
• Implement retry logic with exponential backoff
• Cache responses when data doesn't change frequently
• Use batch requests to reduce API calls

Streams

• Start with narrow filters, expand as needed
• Test filter functions locally before deployment
• Streams will automatically retry on failures
• Monitor stream health via dashboard

Security

• Store API keys in environment variables
• Enable IP allowlisting for production
• Use JWT authentication for sensitive operations
• Rotate API keys periodically

gRPC

• Enable zstd compression to reduce bandwidth (up to 70% for Hyperliquid)
• Implement reconnection logic with exponential backoff — streams can drop
• Use narrow filters (specific accounts, coins, or programs) to minimize data volume
• Set appropriate commitment levels (Yellowstone: CONFIRMED for most use cases, FINALIZED for irreversibility)
• Send keepalive pings (every 10s for Yellowstone, every 30s for Hypercore) to maintain connections

SQL Explorer

• Always filter by time ranges for partition pruning (WHERE block_time > ...)
• Use LIMIT on exploratory queries to reduce data scanned
• Leverage sort keys (check schema reference) for optimal query performance
• Start with pre-built queries and customize for your needs
• Monitor query statistics (rows_read, bytes_read) to optimize performance
