How to Research a Website’s Tech Stack with an AI Agent

Ask an agent using the Glasser Skill to look up one website's technologies and review the source, observation date, and limits of its detections.

What can an agent find out about a website's tech stack?

An agent can retrieve a website technology record and organize the detected tools into a report you can review. That can help you prepare an integration discussion, check a possible ecommerce fit, or decide which technical questions to ask an account.

Give the Glasser Skill one known domain and a clear purpose. The workflow here uses a single-domain technology lookup, then checks the returned categories, source context, and observation date before drawing a conclusion.

One domain keeps the research question specific

A company homepage, storefront, and help center can be different research targets. If you want to understand an ecommerce integration, identify the relevant storefront domain before the lookup. Keep the original target in the report so a finding about one property does not silently become a company-wide claim.

Define the decision you hope to support. “Which detected commerce tools should I verify before an integration call?” gives the agent a useful direction. Asking for every technology the company uses would exceed what a public website record can establish.

Public website detections have a defined reach

The DataForSEO operation available through Glasser describes detected technologies grouped by technology group and category, alongside website information and the crawler's last-visit date. Its inspected input requires a single target.

This is evidence about a website as observed by that data source. An internal CRM or private data platform may leave no visible trace on the chosen property. The broader technographic data guide explains that distinction; this tutorial focuses on obtaining and reviewing a specific website record through an agent.

How do you set up the Skill for this task?

Let your local agent follow the setup guide

Send this in your agent's chat:

set up https://glasser.ai/SKILL.md

Use the official Skill guide for your client. Local setup saves the Skill and prepares the Glasser CLI and browser sign-in. Terminal access, an internet connection, and Node.js 22 or newer are prerequisites for that setup.

Before looking up a domain, ask:

Confirm the Glasser connection with a balance check only.
Do not start a paid lookup.

If your agent already has a suitable technology-data connection, use it first. The task does not require adding a second integration when the first can answer it.

A website technology detection MCP connection is another route

For a supported assistant using MCP, follow the Glasser client guide. Connect Glasser, complete the documented sign-in, and run the same free balance check. You can then use the prompt below with “connected Glasser MCP tools” in place of “installed Glasser Skill.”

Glasser's general discovery tools let the agent find the technology operation. You do not need to install a supplier-specific detection server for the workflow described here.

Which operation should the agent inspect?

Confirm that the operation accepts a specified domain

Ask the agent to find DataForSEO's single-domain technology lookup in Glasser's DataForSEO catalog. The inspected operation is /v3/domain_analytics/technologies/domain_technologies/live, version 2, with target as its only allowed input.

The name alone is insufficient when choosing a data operation. A directory of domains, a list of websites using a named tool, and one website's technology record have different inputs and outputs. Ask the agent to show why its selection fits your known-domain task.

On October 15, 2026, Glasser Inspect listed this operation at $0.012 per call, with the same charge for no result. That is a dated snapshot; Inspect supplies the current contract and price before a new purchase. The operation publishes no fixed output schema.

A prompt for one domain lookup

Replace the domain and research purpose:

Use the installed Glasser Skill to research the public website
technologies detected for [domain].

My purpose is [integration preparation or account research].
Find and inspect a single-domain technology lookup operation.
Show the supported input, current price, and no-result charge.
Wait for my approval before a paid Run.

After approval, make one lookup only. Group the technologies
by the categories actually returned. Include the target domain,
source, available crawl or observation date, and unknowns.
Keep the lookup time separate from the observation time.

Explain what the evidence supports for my purpose. Do not infer
the company's internal CRM, complete software inventory,
security posture, or buying intent.

Include the Run URL, status, provider outcome, and final charge.
Ask before looking up another domain or buying another source.

The report instructions are an editorial recommendation. They do not add input fields or guarantee that the response contains a particular technology, version, or observation history.

How should you read the technology report?

Organize the actual detections before interpreting them

Ask the agent to preserve the original categories where possible. A useful report separates the data it received from the implications you want to investigate.

Report itemWhat it establishesWhat remains to check
Target domainWhich property the record concernsWhether it is the intended storefront or site
Technology and categoryWhat the source reports detectingWhether that tool matters to your integration
SourceWhich provider supplied the recordIts coverage and observation context
Observation dateWhen the source says it observed the siteWhether that evidence is recent enough
Missing fieldsWhich details the response does not establishWhether another source is worth retrieving

Fill these review fields from the actual response. Include version numbers or other dates only when the returned data supports them. Keep missing values visible.

A fresh lookup can return an older observation

The time you asked the agent for a report and the crawler's recorded visit date describe different events. A lookup today can retrieve an observation made earlier. Ask the agent to label both and avoid calling the result a live scan unless the operation's documented behavior and returned evidence justify that description.

If no observation date is available, record that limitation. A technology association may still be useful for preparing a question, while being insufficient for a claim about the site's present configuration.

What should you do with a match or an empty result?

A detection can guide the next conversation

A detected commerce platform can justify asking whether your integration supports the relevant storefront. It does not establish a planned migration, an unhappy customer, or approved spending. Keep those commercial assumptions outside the technology report.

Our recommended next step is to write one question beside each decision-relevant detection. For example: “Does the team responsible for this storefront also manage checkout integrations?” That connects the observation to a useful discussion without claiming knowledge of the internal organization.

If you need to discover companies that use a technology, see the technographic providers guide. That starts from a technology condition, while this task starts from a known domain.

Empty records call for a scope check

An empty lookup gives you no usable detection record for that request. Check the target and the provider outcome before deciding whether another property or source might answer the question. The inspected operation can charge for no result, so another attempt needs an explicit purpose.

Have the agent check the Run status, provider response, and final charge, following Glasser's result guidance. Recover an existing Run after a lost connection before creating a new purchase. Additional domains should be proposed with their costs and approved before expanding the research.

To try the workflow, set up the Glasser Skill and begin with the one domain that matters to your next decision.

Documentation and the Glasser operation were inspected on October 15, 2026. No paid website lookup or detection-accuracy benchmark was performed for this guide.

Questions about website technology research with an agent

Will the agent find every tool the company uses?

A public website record covers the technologies observed by its source. Internal software and tools that leave no detectable signal on that property may remain unknown.

Does an empty result mean the website uses no technology?

It means the request produced no usable technology record. It does not establish that a particular tool is absent, and the applicable no-result charge still needs to be checked.

Can this workflow retrieve WHOIS registration details?

This operation retrieves website technology information. Registration details need a separately verified operation whose inputs support the domain question you want to ask; the technology result does not establish the registrant or registration date.
