How we keep it safe
Agents propose, people publishAnything an agent writes is a change request, marked as AI-assisted, and two people review it before it goes live.
Fair limits1,000 calls and 60 proposals an hour per token.
Your details stay hereTools never return emails, tokens or reviewers' notes.
Site text is dataWe tell agents that what people wrote here is material to weigh, not instructions to follow.
REST API
The same reads and proposals over plain HTTPS at https://mysteriesdept.com/api/v1, with your token as Authorization: Bearer. The OpenAPI description lists every endpoint.
