Create API to show AMM rewards & fees being paid to parent keys

[JonRay15]

API Overview

Since it has been agreed by protocol design / core that rewards for AMMs will be paid to the parent key and not direct to the subkey, we will need an API that tells us what the parent keys have been paid.

UPDATE: We believe that by default the fees and rewards will all turn up on the normal APIs anyway and be sent to the parent key anyway. Therefore the question here is how to make it clear on each of those APIs that the payment is a result of the derived party key. Need to define the full list of APIs we think this impacts.

API request details

• [ ] Ensure that the rewards API has derived party key in it

• [ ] Ensure that the fee stats API has derived party key in it

• [ ] Create a new summary API that tells us per market and per parent key

  • [ ] Maker fees received by parent keys as a result of subkey AMM
  • [ ] LP fees received by parent keys as a result of subkey AMM
  • [ ] Rewards paid to parent keys as a result of dispatch metric = maker fees received
  • [ ] Rewards paid to parent keys as a result of dispatch metric = LP fees received

Filtering requirements (inputs)

• [ ] Parent key
• [ ] Subkey
• [ ] Market ID
• [ ] Fee / Reward type
• [ ] Epoch to
• [ ] Epoch from
