I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

x402-hello

Your first AI agent payment in 60 seconds.

Watch an AI agent make a real USDC micropayment ($0.001) to access a paid API.

Quick Start

# Run directly with npx (no install needed)
npx x402-hello --new-wallet

# Fund your wallet with ~$0.01 USDC + 0.01 SOL
# Then run the demo:
WALLET_KEY="[your-key]" npx x402-hello

What This Demo Shows

Agent requests a paid API
Server returns HTTP 402 with payment requirements
Agent pays $0.001 USDC on Solana (~400ms)
Agent retries with transaction signature
Server verifies payment on-chain and returns data

x402 Protocol

x402 enables HTTP-native payments for AI agents. When an agent hits a paid API, it receives a 402 response with payment details, makes a USDC payment on Solana, and retries with the transaction signature as proof.

No API keys. No subscriptions. Just pay-per-use.
