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

@obul.ai/obulx

Obul x402 CLI and library.

Install

npm install -g @obul.ai/obulx

Direct x402 mode (non-proxy) requires installing the optional addon:

npm install -g @obul.ai/obulx-x402

What It Does

obulx is a CLI for calling x402-protected endpoints. It supports:

  • Proxy mode (via Obul proxy) API key auth.
  • Direct x402 mode with a local private key for signing payments.

CLI Usage

obulx <command>
obulx [options] <url>

Commands:

  • obulx login: OAuth device login. If already authenticated, prints current session and exits. Use --force to re-authenticate.
  • obulx logout: Best-effort refresh token revocation + local credential removal.
  • obulx whoami: Prints the current authenticated user.

Key Parameters

  • --obul-proxy <BASE>: Enables proxy mode and rewrites the URL as BASE/{scheme}/{host}{path}?{query}. Defaults to OBUL_PROXY_URL or https://proxy.obul.ai/proxy.
  • --network <NETWORK>: Required for direct x402 mode. Repeatable or comma-separated.
  • --auto-approve-limit <N>: Optional for direct x402 mode. Integer string in token units. Defaults to 0 (always prompt for approval).
  • --asset <ADDRESS>: Optional in direct mode. Exact match (case-insensitive).
  • -X, --method <METHOD>: HTTP method (default GET).
  • -d, --data <BODY>: Raw request body. Defaults method to POST if method is not set.
  • -H, --header <NAME: VALUE>: Add a request header (repeatable).
  • -v: Show final response status and headers.
  • -vv: Show final request + response.
  • -vvv: Also show probe request + response in direct x402 mode.
  • --force: With obulx login, forces a fresh auth flow even if already logged in.

Environment Variables

  • OBUL_ISSUER_URL: OAuth issuer URL (defaults to https://api.obul.ai) used by login, logout, and whoami.
  • OBUL_PROXY_URL: Override proxy base (defaults to https://proxy.obul.ai/proxy).
  • OBUL_API_KEY: API key for proxy mode.
  • OBUL_X402_PRIVATE_KEY: Private signing key for direct x402 mode.
  • PRIVATE_KEY: Fallback private key for direct x402 mode.

Auth Precedence (Proxy Mode)

When running proxy fetches (obulx [options] <url>), auth selection is:

  1. OBUL_API_KEY env var
  2. OAuth access token from ~/.obul/credentials.json (auto-refreshes with refresh token)
  3. error if neither is available

Notes:

  • Credentials are stored in ~/.obul/credentials.json (file mode 0600).
  • whoami and post-login identity output are JWT-first and opportunistically use /oauth/userinfo when available.

Examples

Login:

obulx login

Who am I:

obulx whoami

Logout:

obulx logout

Proxy mode (API key):

export OBUL_PROXY_URL="https://proxy.devnet.obul.ai/proxy"
export OBUL_API_KEY="your-api-key"

obulx <x402-protected endpoint>

Proxy mode with custom headers:

obulx --obul-proxy https://proxy.devnet.obul.ai/proxy \
  -H "Content-Type: application/json" \
  -H "X-Custom: value" \
  <x402-protected endpoint>

Direct x402 mode:

export OBUL_X402_PRIVATE_KEY="0x..."
npm install -g @obul.ai/obulx-x402

obulx --network base --auto-approve-limit 1000 \
  https://x402.example.com/resource

Direct mode with network priority and asset filter:

export OBUL_X402_PRIVATE_KEY="0x..."
npm install -g @obul.ai/obulx-x402

obulx --network base,optimism --asset 0xA0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 \
  --auto-approve-limit 1000 \
  https://x402.example.com/resource

Verbose output (final request + response):

obulx -vv --obul-proxy https://proxy.devnet.obul.ai/proxy \
  <x402-protected endpoint>

Verbose output (probe + final in direct mode):

npm install -g @obul.ai/obulx-x402
obulx -vvv --network base --auto-approve-limit 1000 \
  https://x402.example.com/resource

CLI

obulx --obul-proxy https://proxy.devnet.obul.ai/proxy \
  -X POST -d '<x402 request body>' \
  <x402-protected endpoint>

Library

import { obulxFetch } from "@obul.ai/obulx"

const response = await obulxFetch({
  url: "<x402-protected endpoint>",
  method: "POST",
  body: "...",
  obulProxy: "https://proxy.devnet.obul.ai/proxy",
  obulApiKey: process.env.OBUL_API_KEY,
  verbose: 1
})

process.stdout.write(response.body)
