What it does

Quicknode is an agent skill from majiayu000/claude-skill-registry. Blockchain RPC and data access via Quicknode. Use when an agent needs to read onchain data (balances, token prices, transaction status, gas estimates, block data) across Base, Ethereum, Polygon, Solana, or Unichain. Supports both API key access and x402 wallet-based pay-per-request access with no account needed. Triggers on mentions of RPC, blockchain data, onchain queries, token balances, gas estimation, block number, transaction receipt, Quicknode, or x402.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `metadata.json`).

It sits in Backend & APIs, covering Smart contracts. It works with x402, Ethereum, Solana and Circle USDC. The repository describes itself as: Searchable Claude Code skills catalog with source-linked guides and generated registry artifacts. The licence is MIT.

Requirements

What it can do on your machine

Read from SKILL.md and the folder at commit 000116a. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- x402.quicknode.com
Also links to:
- quicknode.com
- marketplace.quicknode.com
- github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- PRIVATE_KEY
- API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Quicknode loads about 1.5k tokens when it runs. Until then it costs about 118 tokens; SKILL.md has 403 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~118
When it runs · the whole SKILL.md, loaded when a task matches: ~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description: Blockchain RPC and data access via Quicknode. Use when an agent needs to read onchain data (balances, token prices, transaction status, gas estimates, block data) across Base, Ethereum, Polygon, Solana, or Unichain. Supports both API key access and x402 wallet-based pay-per-request access with no account needed. Triggers on mentions of RPC, blockchain data, onchain queries, token balances, gas estimation, block number, transaction receipt, Quicknode, or x402.

Quicknode: Blockchain Data Access for Agents

Quicknode provides high-performance RPC endpoints across 77+ blockchain networks including all chains Bankr supports: Base, Ethereum, Polygon, Solana, and Unichain.

Two ways to access:

API key: Create a Quicknode account, get an endpoint URL with auth baked in. Full access to all products and settings.
x402 (no account needed): Any wallet with USDC can authenticate and pay per request. Install @quicknode/x402 and start querying immediately.

x402 Access (Recommended for Agents)

x402 is ideal for autonomous agents. No signup, no API keys. Pay with USDC on Base, Polygon, or Solana.

typescript

import { createQuicknodeX402Client } from "@quicknode/x402";

const client = await createQuicknodeX402Client({
  baseUrl: 'https://x402.quicknode.com',
  network: "eip155:84532",   // pay on Base Sepolia (testnet)
  evmPrivateKey: process.env.PRIVATE_KEY,
  preAuth: true,             // pre-authenticates via SIWX for faster payment flow
});

// Pay on Base, query any chain
const res = await client.fetch("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 }),
});

Install: npm install @quicknode/x402

Credit pricing:

Testnet: 100 credits for $0.01 USDC
Mainnet: 1,000,000 credits for $10 USDC
1 credit per successful JSON-RPC response

Full x402 docs: https://x402.quicknode.com/llms.txt

API Key Access

Quicknode endpoints include authentication in the URL:

https://{ENDPOINT_NAME}.{NETWORK}.quiknode.pro/{API_KEY}/

typescript

import { createPublicClient, http } from "viem";
import { base } from "viem/chains";

const client = createPublicClient({
  chain: base,
  transport: http(process.env.QUICKNODE_RPC_URL),
});

const block = await client.getBlockNumber();

Common Agent Operations

Check Native Balance (EVM)

typescript

const balance = await client.getBalance({ address: "0x..." });

Or raw RPC:

json

{ "jsonrpc": "2.0", "method": "eth_getBalance", "params": ["0x...", "latest"], "id": 1 }

Check ERC-20 Token Balance (EVM)

Use eth_call with the ERC-20 balanceOf(address) selector (0x70a08231):

json

{
  "jsonrpc": "2.0",
  "method": "eth_call",
  "params": [{
    "to": "0xTOKEN_CONTRACT",
    "data": "0x70a08231000000000000000000000000WALLET_ADDRESS_NO_0x"
  }, "latest"],
  "id": 1
}

Get Gas Estimate (EVM)

json

{ "jsonrpc": "2.0", "method": "eth_gasPrice", "params": [], "id": 1 }

Check Transaction Status (EVM)

json

{ "jsonrpc": "2.0", "method": "eth_getTransactionReceipt", "params": ["0xTX_HASH"], "id": 1 }

Solana Balance

json

{ "jsonrpc": "2.0", "method": "getBalance", "params": ["WALLET_PUBKEY"], "id": 1 }

Solana Token Accounts

json

{
  "jsonrpc": "2.0",
  "method": "getTokenAccountsByOwner",
  "params": [
    "WALLET_PUBKEY",
    { "programId": "TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA" },
    { "encoding": "jsonParsed" }
  ],
  "id": 1
}

Quicknode Marketplace Add-ons

Quicknode endpoints can be enhanced with Marketplace add-ons. Relevant ones for trading agents:

Token API: qn_getWalletTokenBalance returns all ERC-20 balances for a wallet in one call. No need to query each token contract individually.
NFT API: qn_fetchNFTs returns NFTs owned by an address with metadata.
Solana Priority Fee API: qn_estimatePriorityFees returns recommended priority fees based on recent network activity. Useful for ensuring transactions land quickly.
Solana DAS API: Query compressed NFTs, fungible tokens, and digital assets via methods like getAssetsByOwner and searchAssets.
Metis - Solana Trading API: Jupiter-powered token swaps on Solana. Get quotes and execute swaps via quoteGet and swapPost endpoints. Docs: https://www.quicknode.com/docs/solana/metis-overview

See all add-ons: https://marketplace.quicknode.com/

These add-ons are available on API key endpoints. Enable them in the Quicknode dashboard.
