Accessing Market Data #6

Open tspoff opened 4 years ago

tspoff commented 4 years ago

CoinGecko API is a solid choice, and what we used for Balancer project. Open to other suggestions. From here we can get asset values in any fiat currency, as well as price action within a timeframe.

They also have a nice Javascript wrapper lib already

Will we need to consider rate limits / API keys here?
- Free tier is 100 requests / minute.

What data do we need?

For each asset:

Current price (in USD)
24 hour change

You can make one call /coin/:id but there is a ton of extraneous data

Another route that could be taken:

Aggregate multiple sources into a single "average" price across all markets.
We can start with "free" sources, such as the various on-chain price oracles (Uniswap, Synthetix, dxdx, etc)
If this is a native application, historical price data can be persisted to help with loading.

Great points. We could use the first two to reduce dependency on any given service. Native app isn't in the scope for now - but I think it will need to be for Mix to be competitive.
