Optimize Toolset

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.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@reineira-os/x402

The buyer-side x402 adapter for Arbitrum Sepolia — a thin, batteries-included wrapper over @reineira-os/x402-core's exact client, preconfigured for the eip155:421614 exact (EIP-3009) scheme and Arbitrum Sepolia USDC.

The headline package of x402 — insured, FHE-confidential settlement on the Reineira Settlement Standard.

Install

pnpm add @reineira-os/x402

Usage

import { createX402RssFetch } from "@reineira-os/x402";
import { privateKeyToAccount } from "viem/accounts";

const fetchPaid = createX402RssFetch({ account: privateKeyToAccount(PK) });
const res = await fetchPaid("https://provider.example/job");

createX402RssFetch returns a payment-aware fetch: on an HTTP 402 it signs an exact authorization for the requested payTo/amount and retries with the PAYMENT-SIGNATURE header. A maxValue cap (default 10 USDC) rejects a payment that exceeds the limit before signing.

Built on @reineira-os/x402-core: plain pays settle via transferWithAuthorization; escrow-bound pays settle via receiveWithAuthorization.
