Description
Aureliquo – Quotazioni Oro e Argento adds a white-label valuation flow for gold and silver. Calculations are performed on the WordPress server, while commercial margins, accepted purities, weight limits and quote-lock duration can be configured separately for each metal.
The landing-page entry screen keeps the calculator inactive until the visitor explicitly selects gold or silver. Before that choice, the plugin does not request market prices and does not start its refresh timer.
Main features:
- Gold standards: 24, 22, 20, 18, 14 and 9 karat.
- Silver standards: 999, 925, 900, 835 and 800 fineness.
- Separate margins, weight bands, minimum and maximum weights, quote prefixes, conditions and lock duration for each metal.
- Server-side price retrieval and calculations. Browser-supplied market prices are never trusted.
- Private quote requests available only to administrators.
- Review step, email verification code and HTML tickets for the customer and store.
- Request statuses, internal notes, statistics dashboard and provider monitoring.
- Configurable retention and automatic personal-data anonymization.
- Signed financial snapshot to detect later changes to quote data.
- Nonces, origin checks, request-size limits, rate limiting, idempotency and strict input validation.
Available shortcodes:
[aureliquo_metalli]follows the metals enabled in the plugin settings.[aureliquo_oro]displays only the gold calculator when gold is enabled.[aureliquo_argento]displays only the silver calculator when silver is enabled.
External services
This plugin connects to Gold-API.com to retrieve the current reference price of gold or silver in euros. The market price is required to calculate the indicative valuation shown by the calculator and to let an administrator test the configured price provider.
A request is sent from the WordPress server only in these situations:
- after a visitor explicitly starts the gold or silver calculator and no valid cached price is available;
- when an active calculator refreshes after the configured cache period; or
- when an administrator manually runs the provider diagnostic tool.
Each request contains the selected market symbol (XAU for gold or XAG for silver) and the requested currency (EUR) as part of the API URL. No customer name, email address, telephone number, comment, consent choice, entered weight, selected purity or quote-request data is sent to Gold-API.com.
As with a normal server-to-server HTTP request, Gold-API.com can receive technical connection data such as the website server IP address, request time and the plugin HTTP user-agent. The user-agent includes the plugin version and the website home URL so that the provider can identify the source of the request.
Service provider: Gold-API.com
- API documentation: https://gold-api.com/docs
- Terms of Service: https://gold-api.com/terms
- Privacy Policy: https://gold-api.com/privacy
Market data is indicative and is not a tradable, settlement-grade or investment-advice quote. Site administrators are responsible for confirming that their use complies with the provider’s current terms.
Source code and build instructions
All PHP, JavaScript and CSS included in the distributed plugin are maintained as human-readable source files. The plugin does not include minified bundles, compiled JavaScript or CSS, vendored third-party libraries, or generated production assets.
The maintained source files are included directly in the plugin package, including:
assets/js/frontend.jsassets/js/admin.jsassets/css/frontend.cssassets/css/admin.css
No npm, Composer, webpack or other build step is required. To create an installable package, place the aureliquo-gold-silver-quotes directory in a ZIP archive without transforming the source files.
Privacy
When a visitor submits a quote request, the plugin can store the name, email address, telephone number, optional comment, consent choices and the financial snapshot required to manage that request. Quote requests are stored as private WordPress content and are visible only to administrators with the required capability.
The plugin supports configurable retention periods, automatic anonymization and optional deletion of plugin data during uninstall. The site owner remains responsible for publishing an appropriate privacy notice and selecting lawful retention settings.

FAQ
-
Does the plugin contact price APIs on every page view?
-
No. The calculator remains inactive on the entry screen. The first price request starts only after the visitor chooses gold or silver. Subsequent requests use the configured WordPress cache and refresh interval.
-
Are calculations trusted from JavaScript?
-
No. The server retrieves the market price and recalculates the valuation. Values sent by the browser are validated and are not accepted as authoritative prices.
-
Is the displayed amount a guaranteed purchase price?
-
No. It is an indicative valuation based on the visitor’s declarations and the configured commercial rules. Weight, purity and authenticity must be verified by the business.
-
Who can view submitted requests?
-
Requests use a private custom post type and are available only to administrators with the plugin’s required capability.
