      auth: API key via X-API-Key header (preferred) or api_key query param; sft_ prefix
      pagination: opaque cursor — ?limit (default 50, max 200) + ?cursor from meta.next_cursor; terminates
        when next_cursor is null/absent
      versioning: uri-path v1; fields additive within a version; breaking changes ship under a new version
        with a deprecation window
      timestamps: ISO 8601 UTC — dates YYYY-MM-DD, timestamps YYYY-MM-DDTHH:MM:SSZ, tick t is int64 epoch
        ms
      error_envelope: '{"error":"<snake_case_code>","message":"...","retry_after":<n>} — application/json,
        NOT RFC 9457; switch on `error`'
      rate_limit_headers:
      - X-RateLimit-Limit
      - X-RateLimit-Remaining
      - Retry-After
      idempotency: not applicable — every operation is an HTTP GET, idempotent by method; no Idempotency-Key
        contract exists

    - getSnapshot
    x-apievangelist-gzip-note: 'These operations declare a REQUIRED Accept-Encoding: gzip header and return
      406 gzip_required without it. Most HTTP clients add it automatically; raw fetch/curl does not.'
