Commercial property research
Go into the next conversation with better questions.
Recorded characteristics, ownership context and market evidence can help shape an acquisition-research agenda. The useful part is knowing which assumptions still need checking.

The data core
Property records, energy certificates, planning evidence, corporate ownership, listings and auction results, connected where records can be matched. Examine the unit and building relationship, source dates and unresolved matches before relying on an output.

Frequently asked
Questions we get asked.
What is MarketCode?+
UK property data and analytics to help prioritise opportunities, challenge pricing assumptions and focus further investigation. Access through an AI assistant or REST API; web apps are in early access by request.
What is a skill?+
A short markdown file that tells an agent how to produce a piece of work: which calls, in what order, what they cost, how to lay out the result with every figure cited. Install the plugin in Claude Code, or paste a skill into any other client.
Do I need an API key?+
Not for an AI assistant. The MCP server signs you in with OAuth and never asks for a key. API keys are for the REST API; you create them in the Hub.
Bring a property you know.
Bring an address, site or commercial asset and a decision you need to make. We will examine the evidence, the gaps and a useful next step together.
