Using Predictoor Subgraph

Subgraph URLs

You can query an Ocean subgraph at one of the following:

The subgraph url for each network is in the ppss yaml under "subgraph url".

Typically, these are something like:

• Local (barge)
  • http://localhost:9000/subgraphs/name/oceanprotocol/ocean-subgraph
  • OR http://172.15.0.15:8000/subgraphs/name/oceanprotocol/ocean-subgraph
• Sapphire testnet
  • https://v4.subgraph.sapphire-testnet.oceanprotocol.com/subgraphs/name/oceanprotocol/ocean-subgraph
• Sapphire mainnet
  • https://v4.subgraph.sapphire-mainnet.oceanprotocol.com/subgraphs/name/oceanprotocol/ocean-subgraph

Typical query

For a general overview, here's a good one:

query{
  predictContracts{
    id
    token{
      name
    }
    subscriptions(orderBy: expireTime orderDirection:desc first:10){
      user {
        id
      }
      expireTime
    }
    slots(orderBy: slot orderDirection:desc first:10){
      slot
      roundSumStakesUp
      roundSumStakes
      predictions(orderBy: timestamp orderDirection:desc){
        stake
        user {
          id
        }
        timestamp
        payout{
          payout
          predictedValue
          trueValue
        }
      }
      trueValues{
        trueValue
      }
    }
  }
}

Queries in pdr-backend agents

Agents like predictoor and trader do queries via pdr_backend/util/subgraph.py.

• They call to a subgraph, at a given url, with a particular query
• and they may filter further
