}
Estimate the cost of running a query before and after Isofold optimization. This endpoint is primarily supported for BigQuery, where dry-run mode provides exact byte scan estimates. For other warehouses, estimates are heuristic-based.

​
Request

Make a GET request to /cost with a query parameter: 
curl -G https://api.isofold.com/cost \
  -H "Authorization: Bearer YOUR_API_KEY" \
  --data-urlencode "query=SELECT * FROM users"

​
Query Parameters

ParameterTypeRequiredDescription
querystring✅Raw SQL query to evaluate

​
Response

{
  "original_cost": 0.29,
  "optimized_cost": 0.11,
  "savings": 0.18
}

​
Fields

FieldTypeDescription
original_costnumberCost estimate of the unoptimized query (USD)
optimized_costnumberCost estimate of the rewritten query (USD)
savingsnumberDifference between original and optimized cost

​
Notes

  • On BigQuery, this uses real dry-run estimates.
  • On other engines, costs are approximated using:
    • Column count
    • Join complexity
    • Filter selectivity
  • Use this endpoint to evaluate query rewrites without executing them.
