ai_api_cost
AI API cost
Estimate USD per request, day and month from token counts, caching and published batch discounts. Use for an API workload budget, not chat subscriptions. Model IDs use providerId/id from https://operatornest.com/api/models?subset=pricing; some catalog records are unavailable through MCP. Rates are from the dated catalog snapshot returned with the result.
