Single Valuation Query

query GetValuation($id: ID!) {
  valuation(id: $id) {
    id
    sku
    estimatedValue {
      min
      max
      currency
    }

# Variables

  "id": "val_abc123"
}

Relay Connection (Pagination)

query ListValuations($first: Int!, $after: String) {
  valuations(first: $first, after: $after) {
    edges {
      node {
        id
        sku
        estimatedValue {
          min
          max
        }
        confidence
      }
      cursor
    }
    pageInfo {
      hasNextPage
      hasPreviousPage
      startCursor
      endCursor
    }
    totalCount
  }
}

# Variables
{
  "first": 10,
  "after": "cursor_abc123"
}

Schema Introspection

Query the schema itself to discover types, fields, and directives.

Introspection Query

# Fetch full schema

      kind
      description
      fields {
        name
        type {
          name
          kind
        }
