  Lastline publishes no versioning policy, no deprecation policy, no SLA and no status page. This
  artifact records the ownership/product lifecycle of the company and its API surface, assembled from
  direct evidence gathered on 2026-07-19: live HTTP probes, the TLS certificate on lastline.com, and
  the copyright and support links in the live first-party API documentation. Facts not directly
  evidenced by those probes are marked with their confidence.

ownership_timeline:
- date: '2011'
  event: Lastline, Inc. founded in Santa Barbara, California.
  evidence: Company address published on archived lastline.com — 6950 Hollister Avenue Suite 101,
    Santa Barbara, CA 93117.

  evidence: TLS certificate served for lastline.com / user.lastline.com is issued to "C=US,
    ST=California, L=Palo Alto, O=Broadcom Inc., CN=lastline.com" (DigiCert Global G2, valid
    2026-03-17 to 2026-10-01), probed 2026-07-19.
  confidence: high

versioning:
  scheme: none
  current: null
  docs: https://analysis.lastline.com/analysis/api-docs/html/api.html
  note: The HTTP API is unversioned — no path segment, no version header. Report payloads carry their
    own `report_version` values per report format.
deprecation:
  policy_url: null
  policy_published: false
  sunset_header: false
  note: >-
    No deprecation or sunset policy is published, and no RFC 8594 Sunset/Deprecation header support is
    documented. The only deprecation signalling on the developer surface is parameter-level, inside
    the Python client reference — for example submit_file()'s download_ip, download_port and
    download_url parameters are each annotated "DEPRECATED!" with a named replacement (server_ip,
    server_port, and the download_host/download_path pair respectively).
  deprecated_parameters:
  - operation: submit_file
    parameter: download_ip
    replacement: server_ip
  - operation: submit_file
    parameter: download_port
    replacement: server_port
  - operation: submit_file
    parameter: download_url
    replacement: download_host + download_path
sla:
  url: null
  uptime_target: null
status_page: null
status_page_note: No status page was found for lastline.com or its subdomains as of 2026-07-19.
support:
  url: https://my.vmware.com/group/vmware/get-help
  note: The API documentation's "Contact Us" link points at VMware's help portal.
data_retention:
  documented: true
  note: Analysis data, reports and artifacts are subject to data-retention policies; expired data
    returns ANALYSIS_API_DATA_NO_LONGER_AVAILABLE (123) or ANALYSIS_API_INVALID_ARTIFACT_UUID (114).
