If you are hosting a Frame on your product (you can, they are not Warpcast specific!), you can
  1. Fetch a feed of all Frames using our /feed/frames API
  2. Let users connect Farcaster to your product with Sign In with Neynar or use dedicated signers on our Enterprise plan
  3. Let users create Frame actions on your product directly using Neynar Frame Action POST API
  4. To test Frames on your local machine, set up ngrok and use ngrok as your Frame’s POST URL.
