📦 Prerequisite

You need to create a config.json file in your machine.

See example config.json for requesting data from GuanYu devnet every 5 minutes:

{
  "chainId": "band-guanyu-devnet-2",
  "endpoint": "http://guanyu-devnet.bandchain.org/rest",
  "mnemonic": "final little loud vicious door hope differ lucky alpha morning clog oval milk repair off course indicate stumble remove nest position journey throw crane",
  "cronPattern": "*/1 * * * *",
  "validatorCounts": {
    "minCount": 3,
    "askCount": 4
  },
  "requests": [
    {
      "oracleScriptId": 1,
      "params": {
        "symbol": "BTC",
        "multiplier": 1000000
      }
    },
    {
      "oracleScriptId": 13,
      "params": {
        "base_symbol": "ETH",
        "quote_symbol": "CNY",
        "aggregation_method": "median",
        "multiplier": 1000000
      }
    }
  ]
}

💎 Example Usages

npx @bandprotocol/cron-requester config.json

If the config.json is correctly formatted, you should see something like this:
