It calculates an estimate on demand using Baldwin's existing configurator pricing engine. Do not invent a price or reuse a price returned for a different design. GET endpoint: https://www.baldwinpergolas.com/api/pergola/estimate.php Example — Classic attached pergola, 20 feet wide, 10 feet deep, 8 feet high, default design options, JSON response: https://www.baldwinpergolas.com/api/pergola/estimate.php?product=classic&config=attached&width=240&depth=120&height=96&format=json Example — Classic freestanding pergola, 10 feet wide, 12 feet deep, 8 feet high, default design options, JSON response: https://www.baldwinpergolas.com/api/pergola/estimate.php?product=classic&config=freestanding&width=120&depth=144&height=96&format=json - For Classic designs, `product=classic`, `config=attached` or `freestanding` (or `colonnade` where supported); `width`, `depth`, and `height` are in inches. Other optional settings include `colStyleIdx`, `beam`, `tail`, `colorKey`, `columnQTY`, `rafterSpacing`, and `purlinSpacing`. - Use `format=json` for structured results; omit it for an HTML estimate page. - Construct a NEW request URL using the customer's chosen configuration. Do not fetch an old example URL and treat its price as applicable to another design. - Before quoting a result, verify that response `configuration.config`, `configuration.width`, `configuration.depth`, and `configuration.height` match the requested design. If they do not match, report that the result is mismatched and do not quote it. - Use `price`, `currency`, `priced_at`, `price_description`, `disclaimer`, `specifications`, and `configurator_url` from the actual response. Describe the pergola as a complete custom-crafted kit when the response says so, not merely raw materials. - Do not assume the entered dimensions are column-center or overall measurements without confirming how the selected configurator defines them. Do not invent overhangs or add dimensions to the user's requested size. - An AI web tool may cache, rewrite, or refuse parameterized URLs. If the returned design does not match the requested URL, do not present its price as current for the requested design. - Estimates are not binding quotations. Confirm shipping, installation, footings, electrical, permits, tax, and other project-specific charges separately.
