Api Endpoint

Tabular Contract Audit

Audit your own delimited data against a contract you declare, and get one pass/fail plus the exact row and clause of every breach. Checks types, required values, enums, numeric bounds, lengths, patterns, uniqueness, composite primary keys, null-rate ceilings, header drift and encoding damage in one pass. A pass means the audit was complete and nothing broke, so a file beyond the bounds reports incomplete rather than passing. Nothing is fetched: you supply the rows.
