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 containing a list of all submitted properties with computed financial metrics (such as net yield) and a second list sorted by net yield descending, allowing direct comparison. Includes a workflow identifier and limitations note clarifying that ownership, taxes, financing and transaction costs are not verified.
Example use cases
Buy-to-let shortlist ranking
“I'm deciding between four buy-to-let properties. Can you screen them and rank by net yield? Maple Court: value £250,000, rent £16,000/year, maintenance £1,800. Brook Lane: value £180,000, rent £13,200/year, maintenance £1,200. Park View: value £350,000, rent £22,000/year, maintenance £2,500, service charge £1,000. Harbour Mews: value £420,000, rent £24,000/year, maintenance £3,000, vacancy 8%.”
Portfolio rebalancing review
“I manage a small property portfolio and want to figure out which assets are dragging down overall yield. Here are my six properties with their values, annual rents, and cost estimates — can you run a portfolio screen and sort them by net yield so I know where to focus?”
Pre-acquisition screening
“Before I make an offer, I want to benchmark this new flat against two properties I already own. The new one is valued at £195,000, earns £12,600 rent, costs £900 maintenance and has a 3% vacancy rate. My existing ones are Birch House (£310,000 value, £19,200 rent, £2,100 maintenance) and Station Road (£275,000 value, £17,000 rent, £1,600 maintenance, £800 service charge). Which has the best net yield?”
Technical details
Endpoint
POSThttps://api.rafidsystem.com/api/v1/x402/property/portfolio-screen?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to compare 2–100 investment properties side-by-side on financial performance metrics, especially net yield, in a single structured call. Prefer it over manual calculations or general-purpose LLM reasoning when you need deterministic, reproducible yield rankings across a portfolio. It is not a substitute for full property due diligence (ownership verification, tax, financing) but is ideal for shortlisting and prioritisation tasks.
Side effects
- Fewer than 2 properties supplied — minimum 2 required
- Property missing required fields (name, propertyValue, annualRent) — validation error
- Both 'maintenance' and 'maintenanceCost' supplied simultaneously — schema conflict
- Property value of 0 or negative — validation error
- More than 100 properties submitted — exceeds maxItems limit
- Payment not completed via x402 — 402 Payment Required response
- Extremely large numeric values exceeding 1,000,000,000,000 — schema validation failure
