Paygent Integration

Overview

Paygent is a specialized, usage-based billing platform designed exclusively for AI voice agents.

If you are building voice agents for clients or offering them as a SaaS product, calculating margins across different AI providers (LLMs, TTS, STT, and Speech-to-Speech models) can be incredibly complex. Paygent solves this by serving as your centralized billing engine.

How you charge your customers

Instead of building custom tracking infrastructure, you simply connect your Talkr workflow to Paygent. As your agents handle calls, Talkr passively calculates the exact multimodal token usage and audio duration.

This data is securely exported to Paygent after every call, where your custom pricing margins (rate cards) are applied. This seamless flow allows you to automatically invoice your end-users for the exact infrastructure they consume — turning your AI agents into a scalable, profitable business with zero engineering overhead.

Prerequisites

• A Paygent account
• A Talkr voice agent workflow

Setup

1. Create an agent and configure pricing in Paygent

Before connecting Talkr, you must register your agent in Paygent and define how you want to charge your customers.

Log in to Paygent and click Create Agent. You will be prompted to define your agent's core details, including the Agent Name and Agent ID:

Next, set the Indicator Name. This is the billing event identifier you will pass from Talkr (e.g. per-minute-call) to tell Paygent which rate to apply for this agent's calls:

Finally, you will configure your Pricing Strategy. Paygent allows you to set custom markup rates (rate cards) for every modality. You can define exact margins for Speech-to-Text (STT) seconds, LLM tokens, Text-to-Speech (TTS) characters, and total call minutes:

Once your pricing is configured, confirm your setup. You will use the Agent ID and Indicator from this process to connect your Talkr workflow.

2. Gather your Paygent credentials

You'll need three core values from your Paygent dashboard to link your Talkr agent:

3. Add the Paygent node to your workflow

In your Talkr workflow editor, click Add node and scroll to the Integrations section. Select Paygent. The node will appear on your canvas with a Not configured badge.

4. Configure the node

Click on the Paygent node and fill in the following fields:

• Paygent API Key — Your pg_live_... secret key
• Agent ID — The unique agent identifier from Paygent
• Customer ID — Your Paygent organisation ID
• Indicator — The billing event name (defaults to per-minute-call)
• Enabled — Toggle on to activate the export

Click Save, then Publish your workflow.

5. Verify the connection

Make a test call through your agent. Once the call completes, check your Paygent dashboard. The billing event and detailed multimodal usage breakdown should appear under your configured Agent ID within a few moments, with your configured pricing margins automatically applied.

Disabling the integration

To temporarily stop exporting usage data to Paygent, open the Paygent node configuration and toggle Enabled off. Your credentials are preserved — toggle it back on anytime to resume tracking.
