The short version of why: programming languages have had interfaces and duck typing forever. You code to a shape, not an implementation. The web never got a successful equivalent at the network boundary. OpenBindings is an attempt at that.

What's here today: - The spec (v0.1.0): https://openbindings.com/spec - ob CLI: https://github.com/openbindings/ob - Go SDK: https://github.com/openbindings/openbindings-go - TypeScript SDK: https://github.com/openbindings/openbindings-ts - Binding executors for different protocols

Fastest way to try it: brew install openbindings/tap/ob ob demo

That starts a coffee shop service on six protocols. `ob op exec localhost:8080 getMenu` calls it. The CLI discovers the OBI (OpenBindings Interface) at /.well-known/openbindings and handles the rest.

Would love feedback on the spec design.

Except for the central registry of "stripe" and "payment-processor"?

Even purely on the technical level, this seemingly hasn't internalized the lessons of https://xkcd.com/927/

Man I hate JSON so much.
