FAQ

Answers.

What is the Searchland API?

A way to access Searchland's national property and planning datasets programmatically, so the data lives inside your own systems, dashboards or applications — no platform UI required.

Do I need a Searchland licence to use the API?

No. API access is offered as a standalone, separately-priced service. A platform licence does not include API access, and the API does not require one.

Does a Searchland license include API access?

No. API access is not included within standard Searchland platform licences.

A Searchland licence gives users access to the full platform interface, allowing them to visually explore planning data, ownership records, constraints and development opportunities.

API access is offered as a separate paid service for organisations that need to integrate Searchland data directly into their own software, databases or internal tools.

If your team simply needs to search, analyse and export data, the platform will usually be the most efficient option.

What data can I access?

The same datasets that power the platform: planning applications & appeals, documents, ownership & title, constraints & policy, strategic land (SHLAA, allocations), energy & infrastructure, and sold-price comparables.

Bulk download, REST query, or GIS integration?

Bulk for large national datasets and internal databases. REST for real-time per-query access inside your software. GIS for spatial analysis directly in ArcGIS or QGIS alongside your own layers.

Should I use the API or MCP?

Both reach the same Searchland data. Choose the API when you want to build it into your own software, pipelines or GIS programmatically. Choose MCP when you'd rather ask questions in natural language through an AI assistant like Claude or Copilot — no integration work, answers in seconds.

What are typical API use cases?

Pulling planning applications for a location into an internal deal-tracker, enriching your own GIS or analytics dashboards, building custom site-sourcing tools, or syncing ownership and constraints data into a database — anywhere you want Searchland data requested automatically by your own software.

Can I connect Searchland data directly to my GIS software?

Yes. Searchland datasets can be integrated directly into GIS tools such as ArcGIS or QGIS, allowing your team to analyse planning and property datasets alongside other spatial layers.

This is commonly used by planning consultancies, infrastructure teams and research organisations that rely heavily on GIS workflows.

Do I need a developer?

Yes — integrations involve writing code to query, process and store the responses. If your team has no technical resource, the platform is usually the better route.

Can I see a sample before buying?

Yes. We can share a sample dataset or schema overview so your technical team can confirm the structure fits before integrating.
