BIG UPDATE: 1,000,000 free RPC requests per month, per agent, are now available via x402 on Quicknode.
No account, no API key. Connect a wallet, pay in testnet @USDC or USDG, and query 140+ networks. Refreshes every month.
Two ways to pay. Charge mode for one-off calls. Session mode opens a payment channel and uses off-chain vouchers, so high-frequency traffic settles in batches at a fraction of a cent per call.
With MPP your agent pays as it makes requests, straight over HTTP. It can also run over MCP, so AI tools can pay for blockchain calls inline, right inside the tool call.
1,000,000 free requests per month, per agent, now available with @mpp on Quicknode. No account, no API keys. Pay with a stablecoin and query 140+ networks.
Refreshes every month.
Fully typed means your editor catches a wrong field or bad enum before you run anything. Not in prod at 2am.
That goes for AI agents, too. Code written against the SDK either compiles or it doesn't ship.

We rebuilt how you talk to the entire Quicknode platform.
One typed SDK. Four languages from one core.
Endpoints, Streams, Webhooks, and KV Store in single calls that autocomplete in your editor.
And we compared old vs new live👇
📣 SQL Explorer is now x402 + MPP enabled
Agents and apps can query nearly 500B rows of onchain data and pay per call. No API key, no subscription.
Data on demand, settled per request.
The public API was never meant to carry production trading workloads.
The @HyperliquidX team is saying it out loud now. Sergen wrote up exactly what's changing and what to move to

Hyperliquid just slowed down their public WebSocket API.
- l2Book: 20 levels every 5s
- allMids: every 5s
- spotAssetCtxs / allDexsAssetCtxs: every 15 seconds
Their own team's advice: "run a non-validating node."
Here's what changed, why it matters, and what to do next. 🧵
