Get Calculator Schema
Get the input and output schema for a calculator, generated from its reviewed contract: parameter types, units, allowed dropdown values and definitional bounds, plus outputs keyed by named range (including the status output). Table inputs carry a 'grid' block giving the exact number of rows to send, the column layout, which columns are editable, and how to shape a row; a table whose 'grid' block says writable=false cannot be supplied at all. Optionally resolves one immutable platform version. Re
Run Calculator
Run a calculator with the given inputs. Inputs are validated against the resolved version's reviewed contract and computed by SpreadsheetWeb through the same proxy as the web channel. An optional platform_version pins both validation and computation to that immutable version. Returns outputs keyed by named range (including the status output) and trust metadata with a citation URL. Results are informational and not professional advice; the applicable notice is returned in the trust block.
Search Calculators
Search the LogicCommons calculator catalog by keyword and optional category. Returns matching published calculators with slug, name, summary, category, a citation URL, and trust metadata.
