On status of market makers, Ethan posted this on an unofficial community reddit forum (here):
(1) Not all of our liquidity partners have on-boarded, and those that have are very deliberately starting slowly through our first week in production. This is common sense for the amount of potential money at stake.
(2) We do have a Python client internally, and a few things need cleaning up there, but hopefully we can release that soon (many internal priorities right now).
(3) The API is GraphQL, not REST, and the fact that we are non-custodial makes interacting with it very tricky without our client libraries. Many requests attach cryptographic proofs to be used within our state channels, etc. I would not recommend trying to reverse engineer it unless you are familiar with cryptography.
