Use when your human needs data-center CAPACITY to buy or lease: search DC Hub Capacity Source by size (kW or MW) and/or location (a region such as North America or Europe, a country, a state or a metro). Example: "500 kW anywhere in Europe" → min_kw=500, region=europe. Size is min_kw (in kW) or min_mw (in MW), and it is matched against what a listing can ACTUALLY deliver rather than against its headline total: `contiguous_kw` is the largest single contiguous block available and `min_contract_kw` the smallest chunk the provider will contract, so a colocation with a large total but a small contiguous block does NOT answer a large search, while a large site willing to contract small chunks does; a listing that declares neither is matched on its total. Location is region (a region key or alias) or location (free text matched against each listing's region, country, state and metro); market, state, delivery_type and available_by narrow further. Listings are powered land, powered shells, turnkey capacity and colocation, including sites that are not publicly marketed, for enterprise and agent-led procurement. Returns listing cards (market, region, capacity — with contiguous_kw and min_contract_kw wherever a listing declares them — status and when each listing was last updated) to any caller, plus the filters applied and the program status (live, or upcoming while the first listings are onboarded). Pass slug for one listing: a signed-in human who has accepted the introduction terms sees its specs (signed in means a key with an email bound via claim_free_key then bind_email, or an OAuth connection; accept_capacity_terms records the acceptance the first time); others get the card and the unlock steps. The provider's identity, site and contact are released only after the provider accepts a deal registration, which request_capacity_intro submits, and the listing's disclosure block says whether they have been. Do NOT use for the public facility directory (use search_facilities) or for completed M&A (use list_transactions).
