How this service works
Rafid Agent API provides structured intelligence and paid APIs for AI agents across property, company and risk, supplier, finance, document, website, automotive, logistics, recruitment, trading, voice, video and business-planning workflows.
Output
Returns a JSON object with the estimated annual maintenance cost (in OMR), the monthly reserve amount, the maintenance percentage applied, the assumptions actually used (units, age, annual rate, additional unit cost), and the calculation methodology as a human-readable string explaining the formula.
Example use cases
Rental property maintenance budgeting
“I own a 5-unit apartment building worth OMR 500,000 and it's about 8 years old — can you estimate how much I should be setting aside each year and each month for maintenance?”
New property investment reserve planning
“I'm buying a commercial property valued at OMR 250,000, it's brand new (0 years old) with just 1 unit — what's a reasonable annual maintenance reserve I should plan for?”
Multi-unit building cost forecasting
“I manage a 50-unit residential complex valued at OMR 2,000,000 that's 20 years old. Can you calculate the recommended annual and monthly maintenance reserve using a 1.5% annual rate and an additional unit cost of OMR 40?”
Technical details
Endpoint
POSThttps://api.rafidsystem.com/api/v1/x402/maintenance/estimate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick heuristic-based maintenance cost estimate for a property given its market value and unit count, especially in Omani real estate contexts (outputs in OMR). It is best for budgeting, reserve fund planning, and investment analysis workflows where a fast approximation is acceptable. Not suitable when property-type-specific or area-specific precision is required, as the methodology is an uncalibrated percentage-of-value heuristic.
Side effects
- Missing required propertyValue — returns validation error
- propertyValue of 0 or below minimum — rejected by schema
- units exceeding 10,000 or below 1 — out-of-range error
- ageYears exceeding 200 — schema validation failure
- annualRatePct or additionalUnitCost outside allowed bounds — validation error
- Payment not provided or insufficient USDC — x402 payment required response
