Two weeks ago Neptyne, my startup, announced that you can now access the OpenAI APIs like ChatGPT for free when building apps inside Neptyne. We’re happy to now announce that we’ve extended this capability to four more APIs that would normally require registration and payment.

How does this work? It’s easy. You just call the API as you always would, but there is no need to provide a token in the headers, url or wherever the API expects it. The Neptyne environment will detect that you are trying to access the API and add a token on the fly. Of course there is no such thing as a free lunch, but in this case there is a free starter — we give you enough credits to explore and if you need more, you can always upgrade to Neptyne Pro.

Which APIs can you use for free today?

  • OpenAI. This is not new but still a great way to get started with building AI apps
  • Web search. If you build lang-chain type of applications asking the AI to generate search queries to find detailed information is a powerful pattern. Currently we’re using Bing
  • Web page rendering. Scraping the web pages by just getting the html doesn’t cut it anymore in today’s web. PhantomJsCloud renders pages in a browser, executing javascript and everything. You can now use this directly from your favorite spreadsheet.
  • Geocoding. If your AI has suggested some web searches and you’ve successfully gotten the contents of the results, maybe you want to show things on a map. Use Google’s geocoder without a key to get started.
  • Financial information. Lots of people use Neptyne to build financial applications. The iexfinance API gives you access to a wealth of financial information — from real time quotes, to crypto to historical information.

We can’t wait to see what you’ll be able to build using these APIs now that you don’t need to register and bother with keys. If you need inspiration, have a look at this tyne to find beer gardens — it uses 4 of the APIs described above!
