Gateway is work-in-progress
Gateway support is planned for api.horse, but it is not implemented yet.
API horse is a side project, so larger features like this need focused time to design and build well.
What is the gateway feature?
The gateway will let you intercept the full request-response flow of a live API. Instead of pointing your application directly at the remote API, you will point it at an api.horse gateway endpoint.
Once configured, the gateway will proxy the remote API and allow the complete traffic to be observed, logged, and shared: requests going out, and responses coming back.
This should make it much easier to debug real integrations, inspect production-like traffic safely, and collaborate with other people using the exact same API conversation.
Support development
If this is a feature you want, sponsoring the project helps me justify spending more time on it and move it closer to release.
