origami-js-mill-coingecko

This repository contains an Open Oracle Origami JS Mill for CoinGecko.

For best results, use in conjunction with the Open Oracle Origami JS SDK.

When used with the SDK, this mill provides price feed data from the CoinGecko Simple Price endpoint while bringing you one step closer to launching your very own custom Open Oracle Origami Curator Node.

Any form, any shape. Web3’s modular open oracle.

Quick Start

Install SDK

npm install @open-oracle-origami/origami-js-sdk --save

Install Mill

npm install @open-oracle-origami/origami-js-mill-coingecko --save

Code

The code below demonstrates how to attach a mill to a curator. This is a partial implementation of a curator. To be fully functional, a curator must also plan at least one workshop and one museum.

For more information on how to use a curator, please see the Open Oracle Origami JS SDK.

import { Curator } from '@open-oracle-origami/origami-js-sdk'
import CoinGeckoMill from '@open-oracle-origami/origami-js-mill-coingecko'

const curator = Curator.create({ id: 'my-curator' })

const mill = CoinGeckoMill({
  simplePriceParams: {
    ids: ['bitcoin'],
    vs_currencies: ['usd'],
  },
})

curator.plan(mill).start()

This is an example of how to test the mill output.

import CoinGeckoMill from '@open-oracle-origami/origami-js-mill-coingecko'

const mill = CoinGeckoMill({
  simplePriceParams: {
    ids: ['bitcoin'],
    vs_currencies: ['usd'],
  },
})

mill.start((id, data) => {
  console.log(data)
})
