What is quicknode-skill?

A guide for using QuickNode, a service that provides blockchain network access and data tools across many chains.

Use it to access blockchain data through RPC, streams, webhooks, WebSockets, Solana or HyperCore gRPC, SQL, token and NFT data, swaps, or related APIs. It defaults to test networks when no network is specified.

It helps choose the right blockchain connection, real-time data method, and safety checks before reading data or creating paid or writable resources.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add quiknode-labs/blockchain-skills --skill quicknode-skill

Clone the repo

git clone --depth 1 https://github.com/quiknode-labs/blockchain-skills

Made for: Claude Code, Codex.

Its marketplace also offers this one on its own, as the plugin blockchain-skills — /plugin install blockchain-skills after adding the marketplace above.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00093	$0.11998
Opus 5.5	$0.00037	$0.04799
Sonnet 5.5	$0.00019	$0.02400
Haiku 4.5	$0.00009	$0.01200

Measured 1mo ago against content hash 2e2b3a961854, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade B, and why

quicknode-skill scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

const response = await client.fetch("https://x402.quicknode.com/ethereum-mainnet", { method: "POST",

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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 (Solana gRPC/Blazar WSS/HyperCore gRPC) 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.

What ships with it

24 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

quicknode-skill is a skill published in the GitHub repository quiknode-labs/blockchain-skills (19 stars, last pushed 2mo ago), licensed MIT. It adds 93 tokens to every session and 11,998 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
