Publish Quotes

To submit a quote to the orderbook, POST quotes can be used. In the background, we will take this quote an submit an event on Arbitrum Nova on the users behalf. One the quote event is generated on Arbitrum Nova, it will be added to the orderbook.

Publish Quote Example

// Javascript Sample Code
const { fetch } = require ('cross-fetch')
const { parseEther } = require("ethers");

const url = 'https://test.orderbook.premia.finance/quotes'

// Free or Paid Tier API KEY
const MOCK_API_KEY = '3423ee2bfd89491f82b351404ea8c3b7'

// object array of one or more quotes
const mockQuotes = [{

Get Quotes

When using GET quotes, orders are returned based on the params details provided. quotes endpoint is ideal for determining which order(s) will satisfy a specific order size and side. The returned quotes are ordered by price, and only the order(s) that satisfy the size (cumulatively) will be returned.

Additionally, it is possible to receive RFQ quotes along with public quotes by specifying a taker address. The allows users to find the best possible public/private quote combination for a particular quote size.

Get Quotes Example

// Javascript Sample Code
const { fetch } = require ('cross-fetch')
const { parseEther } = require("ethers");

const baseUrl = 'https://test.orderbook.premia.finance'

// Free or Paid Tier API KEY
const MOCK_API_KEY = '3423ee2bfd89491f82b351404ea8c3b7'

// Params
const poolAddress='0xb9e594644D3BB24cfcBa3FA0289F18dB7cf81573'
const size= parseEther('5').toString()
const side='bid' //Side is 'ask'('bid') if the intention is to buy(sell). 
const chainId='421613'


async getQuotes(_addr, _size, _side, _chainId){
  const url = `${baseUrl}/quotes?poolAddress=${_addr}&size=${_size}&side=${_side}&chainId=${_chainId}`
	
  const response = await fetch(url, {
    headers: {
      'Content-Type': 'application/json',
      'x-apikey': MOCK_API_KEY
    }
  })
	
  if (!response.ok) {
    console.error('Request failed: ', await response.json())
    throw new Error(`Failed to fetch quote: ${response.statusText}`)
  }
	
  const quotes = await response.json()	
  
  return quotes
}

getQuotes(poolAddress, size, side, chainId)

Get rfq_quotes

When publishing an RFQ, users can listen for quotes via WEBSOCKET or use the rfq_quotes endpoint to retrieve only RFQ quotes via REST API.

Get RFQ Quote Example

// Javascript Sample Code
const { fetch } = require ('cross-fetch')

const baseUrl = 'https://test.orderbook.premia.finance'

// Free or Paid Tier API KEY
const MOCK_API_KEY = '3423ee2bfd89491f82b351404ea8c3b7'

// Params
const poolAddress='0xb9e594644D3BB24cfcBa3FA0289F18dB7cf81573'.toLowerCase()
const side='bid'
const chainId='421613'
const takerAddress = '0xd18EE1c241e7A7e59797763C94d2Bd8C9169c831'


async getRfqQuotes(_addr, _side, _chainId, _taker){
  const url = `${baseUrl}/quotes?poolAddress=${_addr}&side=${_side}&chainId=${_chainId}&taker=${_taker}`
	
  const response = await fetch(url, {
    headers: {
      'Content-Type': 'application/json',
      'x-apikey': MOCK_API_KEY
    }
  })
	
  if (!response.ok) {
    console.error('Request failed: ', await response.json())
    throw new Error(`Failed to fetch quote: ${response.statusText}`)
  }
	
  const rfqQuotes = await response.json()	
  
  return rfqQuotes
}

Get Orders

GET orders is a general purpose query of orders in the orderbook. Many of the params are optional to suit the needs of the query. Orders are returned in descending order based on the timestamp in which they were created.

Good To Know: size param in GET orders is not the same as size param in GET quotes. See param descriptions.

Get Orders Example

// Javascript Sample Code
const { fetch } = require ('cross-fetch')

const baseUrl = 'https://test.orderbook.premia.finance'

// Free or Paid Tier API KEY
const MOCK_API_KEY = '3423ee2bfd89491f82b351404ea8c3b7'

// Params
const poolAddress='0xb9e594644D3BB24cfcBa3FA0289F18dB7cf81573'
const chainId='421613'


async getOrders(_addr, _chainId){
  const url = `${baseUrl}/orders?poolAddress=${_addr}&chainId=${_chainId}`
	
  const response = await fetch(url, {
    headers: {
      'Content-Type': 'application/json',
      'x-apikey': MOCK_API_KEY
    }
  })
	
  if (!response.ok) {
    console.error('Request failed: ', await response.json())
    throw new Error(`Failed to fetch quote: ${response.statusText}`)
  }
	
  const orders = await response.json()	
  
  return orders
}
