**Required Credentials:**

* `apiKey` — your BuiltWith API key

***

## Domain Intelligence

Identify the complete technology stack running on any domain, with per-path breakdowns and detection history.

### Domain Lookup

Detect technologies used on one or more domains. Returns a breakdown of all detected technologies per path, with categories, tags, first/last detection timestamps, and optional company metadata.

**Operation Type:** Query (Read)

**Parameters:**

* **domains** `array of strings` (required): One or more domains to analyze (e.g. `["example.com", "acme.io"]`). Maximum 16 domains per request.
* **liveOnly** `boolean` (optional, default: `false`): When `true`, returns only technologies currently active on the site.
* **noMeta** `boolean` (optional, default: `false`): When `true`, excludes company metadata (improves performance).
* **noPii** `boolean` (optional, default: `true`): When `true`, removes personal names and email addresses from results.

**Returns:**

* **results** `array of objects`: One result object per domain queried
  * **domain** `string`: The domain that was looked up
  * **paths** `array of objects`: Technology data broken down by path
    * **domain** `string`: The domain for this path
    * **url** `string` (nullable): The full URL of the path
    * **subDomain** `string` (nullable): The subdomain if applicable
    * **technologies** `array of objects`: Technologies detected on this path
      * **name** `string`: Technology name (e.g. "React", "Google Analytics")
      * **description** `string` (nullable): Description of the technology
      * **link** `string` (nullable): URL for more information about the technology
      * **tag** `string` (nullable): Technology category tag
      * **categories** `array of objects`: Category classifications
        * **name** `string`: Category name (e.g. "JavaScript Frameworks")
        * **tag** `string`: Category tag identifier
      * **firstDetected** `number` (nullable): Unix timestamp of first detection
      * **lastDetected** `number` (nullable): Unix timestamp of most recent detection
  * **companyName** `string` (nullable): Company name from metadata
  * **country** `string` (nullable): Company country from metadata
  * **firstIndexed** `number` (nullable): Unix timestamp when BuiltWith first indexed the domain
  * **lastIndexed** `number` (nullable): Unix timestamp of the most recent index
  * **estimatedMonthlySpend** `number` (nullable): Estimated monthly USD spend on technology

**Example Usage:**

```json
{
  "domains": ["shopify.com", "stripe.com"],
  "liveOnly": true,
  "noMeta": false,
  "noPii": true
}
```

**Example Use Cases:**

* Identify prospects using a competitor's product for competitive displacement campaigns
* Score leads based on their current technology stack (e.g. filter for companies using Salesforce)
* Research what analytics, ad platforms, or CDNs a set of target accounts uses
* Enrich company records with technology profile data

***

## Common Use Cases

**Lead Qualification:**

* Filter prospects by specific technologies they use (e.g. "uses HubSpot" or "uses Shopify")
* Score accounts by technology maturity or spend signals
* Identify accounts ready for migration or upgrade

**Competitive Intelligence:**

* Monitor which domains are using competitor products
* Track technology adoption trends across target segments

**Enrichment & Research:**

* Append technology stack data to CRM records
* Research a domain's tech stack before a sales call or demo
