GWI’s Platform API delivers human-verified data as structured JSON into your warehouse, BI tools, and models, refreshed automatically and ready for your team to build on.
Platform API
Ground every dashboard and model in globally harmonized human data
The human data foundation under everything you build
Whatever your team builds is only as reliable as the data beneath it. GWI’s data is 100% human: real answers from real people, asked the same way in worldwide since 2009.
Teams can access the full range of GWI’s datasets through the API, including Core, USA, Kids, specialist add-ons, and custom research, all in one consistent, documented structure.

Put trusted data to work across the tools your business already uses
Teams use the Platform API to power dashboards, centralize audience data in one place, and automate reports and other assets.
Bring GWI’s verified data into your workflows and reporting so it updates itself. Every release asks the same questions as the last, so nothing you’ve built needs reworking.
Run overlaps, de-duplicated reach, significance tests, and trend projections on data asked the same way in 50+ markets since 2009, then sit it beside your first-party metrics to benchmark against the market.
One expert sets up governed datasets, and the wider team can query them in their usual workflow. Every figure comes from real people surveyed, so that reliability carries into everything built on it.
Surface 100% human data from across GWI’s datasets in your platform, continuously updated, so your customers get insight drawn from real answers, not from scraped or modeled sources.
The aggregated numbers, or the individual rows?
It’s the same GWI data at two levels of detail. Which one you need depends on what you’re building.
Platform API
“62% of home cooks bought a meal kit last month.”
GWI’s aggregated numbers for the audiences you define, structured and kept current in your systems, for dashboards, automation, benchmarking, and products for your clients.

Respondent-level data
“Show me the respondents who make up that 62%.”
The individual, anonymized rows behind those numbers, for when you need to model and segment at the individual level.

Got questions? We’ve got answers.
What can I build with Platform API?
Bring GWI data into dashboards, reporting, analysis, workflows, apps, portals, and other products or systems.
What data can I access?
Depending on your account, you can access GWI’s datasets, including Core, USA, Kids, specialist add-ons, and custom research.
How does Platform API work?
Platform API uses REST to let your systems request specific audiences, questions, markets, and time periods. Results come back as structured JSON, and the documentation covers every endpoint.
Can I combine GWI data with my own?
Yes. Bring GWI results into your own environment alongside your first-party data to benchmark your audience against the market and support other analysis.
How current is the data?
GWI data is refreshed throughout the year, and your connection picks up new data as it’s released.
Can I use Platform API in a customer-facing product?
Yes. You can surface GWI consumer data within your own products and customer experiences, subject to the relevant licensing terms.
What’s the difference between Platform API and respondent-level data?
Both come from the same GWI data. Platform API delivers aggregated numbers for the audiences you define, and respondent-level data delivers the individual, anonymized rows behind them, for your own analysis and modeling.
How do I get started?
