CoinCap MarketService Implementation

[0xean]

Background

Our new web application (app.shapeshift.com) relies on a MarketService for its market data. Currently, we have a single implementation of this MarketService abstraction using coingecko.

We would like to create a second implementation that uses https://coincap.io as the backend.

The interface to implement can be found in here the lib repo:

lib/packages/market-service/src/api.ts

Line 3 in b9d28eb

export interface MarketService {

And this is the Coingecko implementation being instantiated as the sole implementation:

lib/packages/market-service/src/index.ts

Line 15 in b9d28eb

const MarketProviders = [new CoinGeckoMarketService()]

Finally this is the Coingecko implementation itself which can be used as a reference:
https://github.com/shapeshift/lib/tree/main/packages/market-service/src/coingecko

Acceptance Criteria

• Create a new implementation of the MarketService interface for Coincap
• Implement full test suite for the added functionality modeled after coingecko.test.ts

References

• https://docs.coincap.io/

These users each claimed they can complete the work by 264 years, 11 months from now.
Please review their action plans below:

1) zerquix18 has been approved to start work.

Instructions are clear. I'll add a separate provider for the CMC as clean as possible, with tests included.
2) godv2 has applied to start work (Funders only: approve worker | reject worker).

i am backend developer mostly working on go, js/ts, rust projects, new in gitcoin platform. i want to apply for this issue. looks like wrapper around the api. since there is test for conformance this should be easy.
waiting for reply, thanks

@Zerquix18 - just to confim this is for coincap.io not CMC :)
