title: How to use a Chainlink Oracle with Elrond blockchain
body: <p>I'm used to using chainlink with Ethereum blockchain but for basic usage like getting the price of an asset in dollar for example.</p>
  <p>However I'm stuck when I need to do more sophisticated things. To summarize I'm trying to use an oracle that I found on <a href="https://market.link/" rel="nofollow noreferrer">https://market.link/</a> on the Elrond blockchain. For example this one : <a href="https://market.link/nodes/WatchSignals/integration" rel="nofollow noreferrer">https://market.link/nodes/WatchSignals/integration</a>.</p>
  <p>How can I manage to do this ? I spent hours on the chainlink documentation but I couldn't find any clue. Do I need to run my own node, do I need to create an oracle smart contract on the Elrond blockchain, how can I send Link to pay for the service ?</p>
  <p>Does someone know how to do or have documentation that can help me ?</p>
  <p>Thanks</p>
