How this service works
Submit a listing webpage URL to scrape. Scrapes public details, extracts specs, and auto-calculates compliance and financials in a single report. Recommends screenshot fallback if blocked. Cost: $0.05 USDC.
Output
Returns a JSON object with three sections: listing_data (address, city, state, zip, bedrooms, bathrooms, square feet, lot size, year built, property type, raw price, monthly rent), fha_report (is_compliant flag, flagged phrases, violation count, compliant rewrite suggestion), and investor_metrics (purchase price, loan amount, down payment, monthly rent, monthly mortgage, monthly expenses, monthly cashflow, annual NOI, cap rate percent, cash-on-cash percent, DSCR, gross rent multiplier).
Example use cases
Quick investor due diligence on a listing
“I found this property on Realtor.com — https://www.realtor.com/realestateandhomes-detail/456-Oak-Ave_Indianapolis_IN_46204_M12345 — can you pull the specs and tell me the cap rate, DSCR, and whether the cashflow is positive?”
FHA compliance check before publishing
“Before my agent posts this listing live, can you scrape the page at https://www.homesnap.com/listing/789-Elm-St-Indianapolis-IN and flag any Fair Housing Act violations in the description?”
Research comparable investment property
“I'm evaluating a rental property at https://www.redfin.com/IN/Indianapolis/321-Pine-St-46201/home/12345 — pull all the details and show me the NOI, gross rent multiplier, and down payment estimate.”
Technical details
Endpoint
POSThttps://sparks-re-api.sparksdigital-re.workers.dev/property/analyze-url?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a direct URL to a real estate listing webpage and want a single-call pipeline that combines scraping, property data extraction, FHA compliance scanning, and investor financial calculations. Prefer it over the text-submission or screenshot endpoints when the listing URL is publicly accessible without authentication. If the page blocks scraping, fall back to the screenshot endpoint.
Side effects
- Listing page is behind a login wall or bot block — endpoint recommends using the screenshot fallback endpoint instead
- URL is invalid or the page returns a 404 — extraction fails with an error
- Listing page has non-standard HTML layout that prevents data parsing — partial or empty fields returned
- Monthly rent not listed on the page — investor metrics may be incomplete or estimated
- Scrape returns stale cached data if the listing has been updated recently
