Questions

Asked before you got here.

Something else? Talk to us

Is there a free trial?

Yes. You get 14 days with 500 test API credits for building and testing. A card is needed to start the trial. Move to a paid plan when you go to production.

How accurate are the valuations?

Each estimate combines House Price Index and comparable-sales methods, and comes with a confidence score from 0 to 100 plus a low, mid and high range.

Where does the data come from?

Official national and public sources, including HM Land Registry, the Valuation Office Agency, the EPC register, Ordnance Survey, ONS, the Bank of England and the Environment Agency.

Can I use it from Claude, Cursor or ChatGPT?

Yes. Add our MCP server to Claude Desktop, Claude Code or Cursor, or install the ChatGPT Actions integration. Both use the same API key as the REST API.

What are the rate limits?

Limits depend on your plan and come back in the X-RateLimit headers on every successful response. Go over and you get a 429 with the reset time, never a silent failure.

What does coverage look like across the UK?

It varies by source. Sold prices and EPCs cover England and Wales, and each API documents its own coverage and limits.
