Write here about a page that will not load, an API file or an MCP tool that answers wrongly, an email you did not expect, or a question about the terms or the privacy policy. A fact you believe is wrong is welcome too: when a fact is wrong it is corrected in place and dated at the top of its story, and the register is at /corrections/.

Partnership proposals go through the partnership inquiry on the About page, which asks for the format first. What is kept from a message, and for how long, is on the privacy page.

For the programs that read DeepStack
The static API at /api/v1/ and the MCP endpoint documented at /mcp/ are free and need no key. A wrong answer from a tool, a file that will not parse, or a rate limit that bites too early is a support request like any other: send the tool name, the arguments and the time, and nothing else.
