Get IP Geolocation and ASN Data

The core of the Whisper API. This family provides comprehensive threat intelligence and enrichment for foundational internet assets like IP addresses and domains. It's designed for rapid investigation, incident response, and proactive threat hunting.

Indicators

<p>Initiates an asynchronous job to search for indicators matching specific criteria. This endpoint is extremely powerful for infrastructure discovery and threat hunting.</p>
<p><b>Performance Note:</b> Searches on WHOIS fields (like `registrantCompany`) are data-intensive and can take over 50 seconds to complete. This endpoint is therefore asynchronous by design. Poll the `/v1/ops/jobs/{jobId}` endpoint to retrieve results.</p>
<h4>Example Search Queries:</h4>
<ul>
    <li>`registrantCompany:EvilCorp` - Find all domains registered by EvilCorp</li>
    <li>`asn:15169` - Find all IPs in Google's ASN</li>
    <li>`city:"San Francisco"` - Find all IPs geolocated to San Francisco</li>
</ul>


Search Indicators (Asynchronous)

<p>Initiates an asynchronous job to generate potential lookalike domains for typosquatting, homoglyph, and brand protection analysis. This is a powerful tool for proactive threat hunting.</p>
<p>Because this can be a long-running process, the API immediately returns a `jobId`. Poll the `/v1/ops/jobs/{jobId}` endpoint to get the results when the job is complete.</p>


Generate Similar Domains (Asynchronous)

<p>Process multiple indicators (IPs and/or domains) in a single request. This endpoint is optimized for batch processing and can handle up to 100 indicators per request.</p>
<p><b>Performance:</b> Processing time depends on batch size and requested data modules. Expect 5-30 seconds for typical batches.</p>
<p><b>Rate Limits:</b> Limited to 10 requests per minute due to the resource-intensive nature of bulk operations.</p>


Bulk Indicator Enrichment (Asynchronous)

<p>Retrieves comprehensive intelligence for a single IP address or domain. This is the primary, high-performance endpoint for synchronous enrichment.</p>
<p>It aggregates data from multiple sources, including geolocation, WHOIS, DNS, reputation scoring, and relationship mapping. Use the `include` parameter to request additional, deeper data sets that may have higher latency.</p>
<h4>Performance:</h4>
<ul>
    <li><b>Base Response:</b> Typically under 500ms.</li>
    <li><b>With `include=routing`:</b> First request may take up to 5 seconds; subsequent requests are cached for 5 minutes and respond in &lt;200ms.</li>
    <li><b>With `include=ip_intelligence`:</b> Adds 200-500ms of latency for each IP address resolved from the domain.</li>
</ul>


Enrich a Single Indicator (IP or Domain)

<p>Retrieves time-series historical data for an IP address or domain. Track how infrastructure changes over time for threat intelligence and forensic analysis.</p>
<h4>History Types:</h4>
<ul>
    <li><b>whois:</b> Registration history - registrant changes, expiration updates, transfers</li>
    <li><b>routing:</b> BGP routing history - prefix announcements, ASN changes, route hijacks</li>
    <li><b>dns:</b> DNS resolution history - IP address changes, nameserver updates</li>
    <li><b>ssl:</b> Certificate history - cert replacements, CA changes, expiration events</li>
    <li><b>reputation:</b> Risk score history - blacklist appearances, reputation changes</li>
</ul>
<h4>Data Format:</h4>
<p>Timeline with dated snapshots showing what changed and when:</p>
<pre><code>{
  "history": [
    {
      "timestamp": "2025-01-15T10:00:00Z",
      "field": "registrant_company",
      "old_value": "Evil Corp",
      "new_value": "Legitimate LLC"
    }
  ]
}</code></pre>
<h4>Use Cases:</h4>
<ul>
    <li>Tracking domain ownership changes</li>
    <li>Investigating IP reputation degradation</li>
    <li>Forensic timeline reconstruction</li>
    <li>Detecting infrastructure pivots by threat actors</li>
</ul>


Get Historical Data for Indicator

<p>Returns graph visualization data showing relationships between the indicator and related infrastructure. Perfect for interactive network diagrams and threat actor infrastructure mapping.</p>
<h4>Relationship Types Included:</h4>
