Do all your endpoints cover the same properties?
Yes. Every endpoint resolves against the same 29 million England and Wales properties, refreshed daily, so there is no gap where valuation returns but EPC does not.

How do you price it, and can I move my data later?
Pricing is per call in credits, published per endpoint, month to month with no contract. You can export what you pull as CSV or Parquet at any time, so there is no lock-in.

The Problem We Solve

Most platforms run the same tangle: a Land Registry reseller, an EPC vendor, a valuation engine, an address lookup, an environmental feed, a demographics source. That is four to seven contracts, schemas and renewal dates.

A big part of every roadmap goes on wiring those feeds together and patching gaps in coverage. The feature your users asked for waits behind the plumbing.

What changes with Propalt

Outcomes you can rely on

01 · Licensing

Serve Propalt data to your own paying customers

Display derived data in your product, cache responses for the contracted period, and sublicense to your users under defined terms rather than bespoke negotiation. The question your legal team asks first, answered before you integrate.

02 · Vendor consolidation

Six data contracts become one

Swap the Land Registry reseller, EPC vendor, AVM provider, address lookup, market feed and demographics source for one contract. One schema, one invoice, one security review.

03 · Roadmap acceleration

Ship features, not data plumbing

Time to first call under ten minutes. OpenAPI 3.1 spec, MCP tools for Claude and ChatGPT, and copy-paste request samples in ten languages. Spend the quarter on the user-facing feature.

04 · Coverage parity

The same coverage on every endpoint

Every endpoint resolves against the same 29 million UK properties, so there is no silent gap where valuation returns and EPC does not. Your UX does not break because one vendor lost a postcode.

05 · Unit economics

Model gross margin on day one

Published per-endpoint pricing and credit-based usage that scales linearly with volume. A platform serving 10,000 monthly property lookups pays a calculable figure per lookup, before the third vendor renewal rather than after.

06 · AI-ready integration

MCP-first for Claude, ChatGPT and agents

Every endpoint is exposed as an MCP tool. Drop the data layer into your in-product AI features without writing connectors.

One call to get-property returns valuation, EPC, tenure, lease, tax band and title together, replacing several separate vendor lookups.
For developers
Standard REST over HTTPS with a Bearer API key, request samples in cURL, JavaScript, Python, Java, Go and more, plus an MCP gateway for Claude and ChatGPT. Full endpoint directory at propalt.ai/product/forDeveloper.

One contract for every UK property data layer.
