Creating an API to List the Internal Marketplace
We've got some really cool stuff going on with Hive. The new hardfork as well as the HBD stabilizer have really made our stable coin ~stable. The only thing that's missing is external tracking of our internal market.

To this end I followed [CoinGecko's API Guide for spot exchanges](https://docs.google.com/document/d/1v27QFoQq1SKT3Priq3aqPgB70Xd_PnDzbOCiuoCyixw/edit) and built this:
[hive_market_api](https://github.com/disregardfiat/hive_market_api)


Installation:
`$ git clone https://github.com/disregardfiat/hive_market_api.git`
`$ cd hive_market_api`
`$ npm i`
`$ node index.js` || `$ npm start`

It's meant to be run from a witness server WITH the market_history plugin. But you can just as easily point to one. I won't go into any details of routing this through a reverse proxy, but I will say the `CACHEMILSEC` is set to 60 secs because that's the query interval for coingecko. You can make a `.env` file to store your config variables.

```
exports.PORT = ENV.PORT || 3000;
exports.clientURL = ENV.CLIENTURL || "https://rpc.ecency.com/"  // 'http://127.0.0.1:8091/' //Run from same server.
exports.CACHEMILSEC = ENV.CACHEMILSEC || 60000 //1 minute
```

Here's the short list of API

`/api/orderbook/HIVE_HBD`
`/api/historical_trades/HIVE_HBD`
`/api/pairs`
`/api/tickers`
`/api/coin_detail`

Many thanks for this 😃
It's nice to see some big stake holders have voted for you. Sad your proposal for DHF didn't get this good reactions so fast.

Witness server shouldn't be running anything more than required for a block production. A public seed node, which witnesses are expected to run might be a good place for it, as the extra overhead is negligible for the state file and such seed nodes could serve also as basic API nodes (pretty much everything except for account history, that's the most resource hungry could be handled by such simple node)

re: creating-an-api-to-list-the-internal-marketplace
Good job. You might want to add `helmet`

```
import helmet from 'helmet'
api.use(helmet())
```

This kind of quote are aggregated from exchanges like Bittrex... but a lot of volume happens on our internal market that isn't part of these quotes. This should help get better quotes for us.
