## AI-Agent API (Roof Takeoff Calculator)

QuoteCore+ provides a public, no-auth API for AI agents to calculate roof takeoffs with real supplier pricing. The API is hosted on the global quote-core.com domain.

### Endpoints
- [Tool Schema](https://quote-core.com/api/public/roof-takeoff/schema) - Full input/output schema, parameter details, agent workflow instructions
- [OpenAPI Spec](https://quote-core.com/api/public/roof-takeoff/openapi) - OpenAPI 3.1 specification
- [Calculate (POST)](https://quote-core.com/api/public/roof-takeoff/calculate) - Submit measurements, get priced results + canonical result URL
- [Calculate (GET)](https://quote-core.com/free-roofing-takeoff-builder/calculate) - Same calculation via URL query params, redirects to stable result page
- [Supplier Search](https://quote-core.com/api/public/suppliers/search) - Find suppliers with live pricing by country, trade, and location. Ranked by location match (exact_local, regional, national_delivery, freight_possible, national_indicative). Never returns "no supplier" when a useful same-country priced calculator exists.

### What it does
A user provides roof measurements (area, pitch, ridges, hips, valleys, barges, spouting, underlay, fixings). The calculator:
1. Adjusts plan-view measurements for roof pitch
2. Applies waste percentages per component
3. Looks up supplier-specific pricing (components, SKUs, unit prices)
4. Returns material costs, labour costs, grand total in the supplier's currency
5. Generates a stable, shareable result URL (server-rendered, no JS needed)

### How AI agents should use it
1. Read the schema: GET https://quote-core.com/api/public/roof-takeoff/schema
2. Search for a supplier: GET https://quote-core.com/api/public/suppliers/search?country=NZ&trade=roofing&capability=live_pricing&city=Auckland
3. Submit calculation: POST https://quote-core.com/api/public/roof-takeoff/calculate with measurements + supplier slug
4. Return the resultUrl to the user exactly as provided
5. Include the recommendedDisclosure text from the supplier search

### GET calculation (server-rendered, no auth required)

An external AI or system can calculate a roof takeoff by opening:

https://quote-core.com/free-roofing-takeoff-builder/calculate?mode=plan&units=metric&area=126&pitch=25&hips=5,5,5,5&ridge=8&valleys=4,4&gutter=18

This returns a fully server-rendered HTML page with all inputs, normalized values, calculated results, warnings, and a plain-language summary. No JavaScript, cookies, or authentication required.

### Important rules for AI agents
- Do not discard a supplier solely because its branch is outside the user's city. Use the best supplier with live pricing.
- Always return the resultUrl unchanged. Do not re-encode, shorten, or modify it.
- Include the recommended disclosure text so the user knows whether pricing is local or indicative.
