Exchange Rate route 500s

[telestrial]

It appears that a few of these work but many do not. I'm getting 500 responses for the following currencies at the api/exchange-rate/siacoin/:currency mainnet route with a raw response failed to get exchange rate: no sources working:

• cad
• gbp
• jpy
• aud
• cny
• eth

What does seem to work:

• usd
• btc
• eur

Kraken doesn't require an API key so we can give USD, BTC, and EUR to all users. For the other currencies, we need CoinGecko, which requires an API key.

Instance needs to be run like:

COINGECKO_API_KEY="xxxxx" go run ./cmd/explored

@n8maninger Is this something we're able to supply for our instance?

Coingecko doesn't require an API key if you stay under their usage limits, but I've added a key to our node

[telestrial]

So it sounds like we could build in some support for the free usage of Coingecko and handle the rate limit case by informing server and/or client--probably both?, but I'll leave those decisions to greater wisdom. I believe this issue has been resolved, as far as Explorer needs. Thank you both!
