Getting Started with Sportmonks F1 Airnode

This repo contains some basic contracts and scripts to get started with using Sportmonks F1 Airnode.

Installation and Setup

Clone the repo:

git clone https://github.com/api3-ecosystem/sportmonks-example.git && cd sportmonks-example

To install all the dependencies, run the following command:

yarn

• Make credentials.json and add your mnemonic for the network/s you will work with. This wallet needs to be funded to cover the gas costs to deploy/use the contracts.

$ cp credentials.example.json credentials.json

Making a request to the SportMonks F1 Airnode

For the Hackathon, we've integrated and deployed an Airnode for SportMonks F1 API on Goerli Testnet. The following steps are used to deploy a requester that calls the GET Track Winners by Season ID endpoint.

1. Setup

Please follow the setup instructions here before going to step 2

2. Deploy the Requester contract

run the following command to deploy a requester contract

yarn deploy-rrp-requester

this will deploy the RrpRequester contract. You can use this contract as a template to make calls to the Sportsmonk API.

Make sure to change your RRP Address in the deploy/deploy_RrpRequester.js file. Check out the RRP Address for your chain here

Once you run the command note down the RrpRequester address.

3. Deriving the sponsorWallet and funding it

The sponsorWallet covers the gas costs for the fulfillment of the request, so we need to derive and fund it. Run the following command to derive the sponsorWallet making sure that you replaced <YOUR-REQUESTER_CONTRACT-ADDRESS> with the RrpRequester address you deployed in step 3

npx @api3/airnode-admin derive-sponsor-wallet-address \
  --airnode-xpub xpub6C9hFCLsUsU1dPMDaf5cDKiFwxUsET6zmAHxqLWaUBW2jJejjW2GpAxMY4HAeHkBGxeu9hdSyDoLJM7R23jGTfYekWjMcLvtvzrKszarDGY \
  --airnode-address 0xB0B2C57c67aB89c3c65480C4aDE37b66d418c68e \
  --sponsor-address <YOUR-REQUESTER_CONTRACT-ADDRESS>

• You now need to fund the outputted sponsorWallet with some Goerli ETH (around 0.2) for the Airnode to be able to fulfill the request.

4. Making the Request

• To make a request to an Airnode, you'll have to update script/request_rrp.js with your airnodeAddress, endpointId and encodedParameters.

The airnode address will always be 0xB0B2C57c67aB89c3c65480C4aDE37b66d418c68e

For the GET Track Winners by Season ID endpoint, the endpointId is 0x6e58ace4ab94d28da59ec1da675b513cc21a3ca9656228c0b052563a2eb88b3e

You'll have to encode your API parameters using @api3/airnode-abi and pass them to the makeRequest function of the Airnode.

For example, the GET Track Winners by Season ID endpoint takes in a seasonId as a parameter. You would also have to specify the _path of the returned json object that needs to be picked up by the Airnode and _type specifies the datatype of the returned object.

const params = [
      {type: 'string', name: 'seasonID', value: '6'}, 
      { type: 'string', name: '_path', value: 'data.0.id' }, 
      { type: 'string', name: '_type', value: 'int256' }
    ];

the following params are then encoded in the /scripts/request_rrp.js script before being used to make the request to the airnode. If you want to use different parameters or endpointIds you can modify the params object as needed.

run the following command to make the request:

yarn request-rrp

this will make the request, within 100 seconds the sports monk airnode should reply with the response.

5. Using different endpoints

you can use other endpoints apart from Track Winners by Season ID. Here is a list of endpoints and endpointIds

when choosing a different endpointId make sure to modify the /scripts/request_rrp.js script with the appropriate endpointId and params
