Changelog

Every change to the API and MCP server, newest first. A breaking change to version 1 gets at least 90 days' notice here first.

• 9 November 2026

  Pets now have size and age (when the owner gave them), and /pets and search_adoptable_pets filter by both. Lost and found reports can be listed by state. Additions only: nothing changed for existing requests.

• 8 November 2026

  Verified shelters can add and update their own pets: /shelters/{id}/pets (list, add, update, mark adopted, remove), photos, and the same as MCP tools when the server is called with the shelter's key. Turn a key on for your shelter at Your API keys.

• November 2026

  Version 1: read-only endpoints for adoptable pets, lost and found reports, no-kill shelters and breeds, API keys, and the MCP server with five read-only tools. Verified shelters can be enabled to send adopters' messages to pet owners (POST /pets/{id}/inquiries).
