OpenAPI Specification

openapi: 3.2.0
info:
  title: Crosstabs Public Aggregate statistics API
  version: 1.0.0
  description: 'Existing free, accountless endpoints for aggregate integer frequency counts. No respondent-row upload or private project APIs are defined here. All inferential tables require 2–12 rows and columns, rectangular shape, positive row/column margins, and grand total ≤ 1000000000000. Fractional/weighted cells are rejected. These are ordinary independent-frequency methods, not survey-design inference. Source: lib/api/contingency-handler.ts and app/api/v1 route handlers. Unknown /api paths return HTTP 404 JSON with error, code=endpoint_not_found, hint and documentation; HEAD returns the same status without a body. API schema version is separate from application and PyPI package versions. Public REST v1 compatibility policy: breaking changes use a new major URL prefix rather than silently changing /api/v1. Additive response fields may be introduced; clients should tolerate unknown fields. Current v1 endpoints are not deprecated and have no scheduled sunset. If a deprecation is scheduled, the public changelog and developer documentation will publish the affected endpoints, migration guidance and planned dates. This policy is not an availability SLA or a promise of indefinite service. See https://www.crosstabs.com/changelog and https://www.crosstabs.com/developers for published changes and migration guidance.'
