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

Public API Finder

Find free/public APIs for agents, prototypes, demos, and integrations.

Powered by multiple sources plus a curated best-known API layer:

Quick start

npx --yes --package=public-api-finder -- public-api-finder "weather forecast" --no-auth --https
npx --yes --package=public-api-finder -- public-api-finder "crypto prices" --category Cryptocurrency --limit 5
npx --yes --package=public-api-finder -- public-api-finder "jobs" --json
npx --yes --package=public-api-finder -- public-api-finder "payments" --openapi

Why

Agents often waste time wandering the web for APIs. This gives them a small, predictable first stop: search a curated list, filter by auth/HTTPS/CORS, then verify the chosen API docs before coding.

Fits in the Echo agent toolchain

Use public-api-finder when an agent needs a data source for a prototype, bot, dashboard, or demo. It narrows the search space quickly, then the agent should still live-check the selected API docs before writing integration code.

This is the discovery layer for Echo builds that need outside data without starting from a blind web search.

Refresh smoke

npm test
npm pack --dry-run --json

Skill

The package includes an agent skill at:

skills/public-api-finder/SKILL.md

The skill tells agents to prefer the CLI first, then live-check docs/endpoints before building.

CLI options

--category <name>  Filter by category substring
--source <name>    Filter by source: public-api-lists, public-apis, apis-guru, curated
--no-auth          Only APIs with Auth = No
--https            Only HTTPS APIs
--cors <value>     Filter by CORS: Yes, No, Unknown
--openapi          Only APIs with OpenAPI specs
--limit <n>        Max results
--json             Emit JSON
--refresh          Refresh cache

Release Automation

This package is published from GitHub Actions using npm Trusted Publishing with provenance. Releases are built on GitHub-hosted runners and no long-lived npm publish token is required.
