Panxo enables publishers to monetize AI-influenced audiences through Prebid.js header bidding. Two modules work together inside your existing Prebid build.

Module

Purpose

panxoRtdProvider

Detects AI-influenced visitors. Enriches bid requests with audience signals and intent data.

panxoBidAdapter

Sends enriched requests to Panxo demand. Returns premium bids for qualified impressions.

Prerequisites

Requirement

Details

Panxo account

siteId

Found in Dashboard > Integrations - Prebid.js

propertyKey

Found in Dashboard > Integrations - Prebid.js

ads.txt

Required lines shown in Dashboard > Settings > Ads.txt

Installation

Option A: Build from source

gulp build --modules=panxoBidAdapter,rtdModule,panxoRtdProvider

Include alongside your other modules:

gulp build --modules=panxoBidAdapter,rtdModule,panxoRtdProvider,appnexusBidAdapter,rubiconBidAdapter,...

Option B: Pre-built bundle

<script async src="https://assets.panxostack.com/prebid/prebid-panxo.js"></script>

The pre-built bundle includes both the RTD module and bid adapter.

Configuration

RTD Module

pbjs.setConfig({
  realTimeData: {
    dataProviders: [{
      name: 'panxo',
      params: {
        siteId: 'YOUR_SITE_ID'
      }
    }]
  }
});

Detection

Detects whether the current visitor has been influenced by AI assistants

Intent scoring

Scores conversational intent based on session signals

ortb2.user.data enrichment

Enriches ortb2.user.data with AI audience segments

ortb2.site.ext enrichment

Enriches ortb2.site.ext with traffic classification signals

No manual data passing is required. The module handles all enrichment internally.

Bid Adapter

var adUnits = [{
  code: 'ad-slot-1',
  mediaTypes: {
    banner: {
      sizes: [[300, 250], [728, 90], [320, 50]]
    }
  },
  bids: [{
    bidder: 'panxo',
    params: {
      propertyKey: 'your-property-key'
    }
  }]
}];

Storage Access (Prebid v10+)

Required for Prebid.js version 10 and above:

pbjs.bidderSettings = {
  panxo: {
    storageAllowed: true
  }
};

Bid Parameters

Parameter

Type

Required

Default

Description

Minimum CPM floor in USD. Overrides Prebid floor module if higher.

Full Implementation Example

<!DOCTYPE html>
<html>
<head>
  <!-- Prebid.js with Panxo modules -->
  <script async src="prebid.js"></script>

  <script>
    var pbjs = pbjs || {};
    pbjs.que = pbjs.que || [];

    pbjs.que.push(function() {

      // --- Panxo RTD Module ---
      pbjs.setConfig({
        realTimeData: {
          dataProviders: [{
            name: 'panxo',
            params: { siteId: 'YOUR_SITE_ID' }
          }]
        }
      });

      // --- Storage access (Prebid v10+) ---
      pbjs.bidderSettings = {
        panxo: { storageAllowed: true }
      };

      // --- Ad units ---
      pbjs.addAdUnits([{
        code: 'banner-ad',
        mediaTypes: {
          banner: { sizes: [[300, 250], [728, 90]] }
        },
        bids: [
          {
            bidder: 'panxo',
            params: { propertyKey: 'your-property-key' }
          }
          // Add your other bidders here
        ]
      }]);

      // --- Request bids ---
      pbjs.requestBids({
        timeout: 2000,
        bidsBackHandler: function() {
          // Your existing ad rendering logic
        }
      });
    });
  </script>
</head>
<body>
  <div id="banner-ad"></div>
</body>
</html>

Alternative: Standalone Signal Script

For publishers not using Prebid.js, or who prefer external detection before Prebid loads:

<script async src="https://cdn.panxo-sys.com/o/YOUR_ENDPOINT_KEY"></script>

The Signal script sets panxo_uid in localStorage. The bid adapter reads it automatically. This method does not require the RTD module.

IAB TCF Registration

Global Vendor List ID: 1527

Panxo is registered with IAB Europe Transparency and Consent Framework. If you use a CMP, ensure Vendor ID 1527 is included in your vendor list.

Supported Frameworks

Framework

Support

GDPR / TCF 2.0

Consent string passed via user.ext.consent and regs.ext.gdpr

CCPA / US Privacy

USP string passed via regs.ext.us_privacy

GPP

Supported via regs.ext.gpp and regs.ext.gpp_sid

COPPA

Child-directed content flags respected via regs.coppa

pbjs.setConfig({
  consentManagement: {
    gdpr: {
      cmpApi: 'iab',
      timeout: 8000,
      defaultGdprScope: true
    },
    usp: {
      cmpApi: 'iab',
      timeout: 1000
    }
  }
});

User Sync

Pixel-based user sync. Enable in your Prebid configuration:

pbjs.setConfig({
  userSync: {
    filterSettings: {
      pixel: {
        bidders: ['panxo'],
        filter: 'include'
      }
    }
  }
});

First Party Data

The adapter reads FPD from the standard ortb2 config:

pbjs.setConfig({
  ortb2: {
    site: {
      name: 'Example Site',
      cat: ['IAB1'],
      content: { keywords: 'technology, ai' }
    },
    user: {
      data: [{
        name: 'example-data-provider',
        segment: [{ id: 'segment-1' }]
      }]
    }
  }
});

RTD-enriched data merges with any existing FPD configuration.

Supply Chain (schain)

Supply chain information is passed automatically when configured:

pbjs.setConfig({
  schain: {
    validation: 'relaxed',
    config: {
      ver: '1.0',
      complete: 1,
      nodes: [{
        asi: 'publisher-domain.com',
        sid: '12345',
        hp: 1
      }]
    }
  }
});

Floor Prices

Compatible with the Prebid Price Floors Module:

pbjs.setConfig({
  floors: {
    enforcement: { floorDeals: true },
    data: {
      default: 0.50,
      schema: { fields: ['mediaType'] },
      values: { 'banner': 0.50 }
    }
  }
});

The floor bid parameter takes precedence if higher than the floor module value.

Troubleshooting

No bids received

Check Prebid build

Ensure both panxoRtdProvider and panxoBidAdapter are included

Verify credentials

Confirm siteId and propertyKey match your dashboard

Check ads.txt

Must include all required Panxo lines

Expected behavior

Panxo only bids on AI-influenced impressions, not every request

RTD module not loading

# Verify the module is in your build
gulp build --modules=panxoBidAdapter,rtdModule,panxoRtdProvider

Both rtdModule (Prebid core) and panxoRtdProvider must be included.

Low fill rate

This is expected. Panxo targets AI-influenced visitors specifically. Fill rate depends on your AI traffic share, typically 5-25% of total visits. This segment is growing ~200% year over year.
