Everything EyeQuant does in the app is available through the API. Send a design — an image, a live URL, or a video — and get back the same attention heatmaps, scores, and recommendations your team already trusts, in seconds. No user studies, no eye-tracking hardware, no waiting for traffic. Use it to validate creative before it ships, score every asset in your pipeline automatically, or build visual intelligence straight into your own product.

​
What you can analyze

Images

Upload a PNG or JPEG (Base64) to analyze any static design, mockup, or asset — even ones that aren’t publicly hosted.

URLs

Pass any public URL. EyeQuant captures the screenshot for you — desktop, mobile, or generic viewport — then runs the analysis.

Video

Submit a video for frame-by-frame attention analysis of motion content and ads.

​
What you get back

Every analysis runs the same machine-perception models behind the EyeQuant app, returned as clean JSON with time-limited links to rendered maps.

Attention

A heatmap of where viewers look first. Outputs: attentionMap, perceptionMap, hotspotsMap.

Clarity

A 0–100 score for how clear and easy to process a design is, with a supporting map.

Excitingness

A 0–100 score for the visual and emotional impact of a design.

Ad Visibility

A score for how well a creative stands out and captures attention in context.

Why build on EyeQuant

Attention prediction normally takes years of neuroscience R&D and millions of eye-tracking data points to get right. EyeQuant’s models are already there — trained on real eye-tracking research spanning more than 20,000 experiments and 1.6 million data points. You get tested, accurate visual intelligence you can integrate today, instead of building it from scratch.

​
How it works

The API is REST over HTTPS, JSON in and JSON out, authenticated with a bearer token. Analyses run asynchronously: submit a design, poll for the result, then download the maps and scores.

Quickstart

Run your first analysis end to end in a few minutes.

Authentication

Add your API key to every request.

API reference

Every endpoint, with an interactive playground.

​
Getting API access

API credentials aren’t self-serve — contact sales@eyequant.com to request your key. Then head to Authentication to start making calls.
Store your API key securely — in an environment variable or secrets manager — and never commit it to source control.
