CalcsConnect lets your product return a code-checked structural result without your team building and maintaining the calculation logic behind it. Your product sends inputs. Calcs.com runs the calculation against the named standard, then returns results, check outcomes, and a PDF report. This section covers what CalcsConnect does, how to get access, and where coverage starts and stops. It is written for two readers: someone deciding whether CalcsConnect fits their product, and the developer making the first call. The endpoint reference sits somewhere else on purpose. Every endpoint, parameter, schema, and example lives on the Calcs.com developer portal, so there is one source for request detail rather than two that drift apart.
