Trading bots available to rent for a fixed period, with prices and durations. The renter runs the bot themselves with their own exchange key or wallet — nothing is hosted and no credentials are sent to this server. Free to call. Note: no performance or profitability data exists for these bots, so none can be reported; automated trading risks total loss of the funded amount.

Every category and tag in the catalog, with counts. Free. One call reveals the whole shape.
