Introducing Afternic’s Portfolio API, Built for Portfolio Management at Scale

By Afternic | October 22, 2026

Today, we’re opening Afternic Portfolio API access to all sellers, helping you bring Afternic listing data and management actions into the tools you already use to run your domain portfolio.

Managing a large portfolio often means adding new acquisitions, updating pricing, applying Lease to Own settings, and keeping lander strategies consistent across many listings.

With the Portfolio API, you get more control over your listings, with less manual work. You can keep listings aligned with your strategy, spot new opportunities, and build workflows around your existing tools.

Key Takeaways

Afternic Portfolio API access is now open to all sellers, connecting Afternic listing data and management actions to your own portfolio tools.
With the Portfolio API, you can add new listings, edit Buy it Now pricing and Lease to Own settings, control lander settings, and manage Transaction Assurance messages.
The Portfolio API brings demand signals, including leads, GoDaddy searches, and lander views, into your own dashboard.
The Portfolio API works best for sellers who manage large portfolios, while sellers with 500 domains or fewer may prefer to start with Portfolio Agent in the Afternic dashboard.
To get started, create an API key in your Afternic account profile and begin with read-only checks before turning on any workflow that makes changes.

Why use the Portfolio API?

The Portfolio API connects your Afternic account to your own portfolio management tools, so you can add, edit, and manage your listings in real time.

While you can accomplish day-to-day tasks through the Afternic UI, connecting to our API gives you more control over your domains and more time to focus on growing your portfolio.

Here’s how sellers use the Portfolio API most.

Add new listings

If you buy domains regularly, use the Portfolio API to cut the time you spend setting up new listings. You can apply pricing, Buy it Now, Lease to Own, and For Sale lander settings automatically, so new acquisitions match your portfolio strategy from the start.

Edit pricing and Lease to Own

Buy it Now pricing and Lease to Own are two of the simplest portfolio adjustments with real upside. Priced domains allow buyers to take action immediately, while domains with Lease to Own are up to 3x more likely to sell than domains with Buy it Now alone.

With the Portfolio API, you can review and update pricing and Lease to Own settings across your whole Afternic portfolio.

Control lander settings and defaults

Our For Sale landers are a key part of any sales strategy. They tell visitors your domain is available, and they can reduce your commission rate by 33% on Boosted domains. They can also increase sales by up to 25%*. Choose your lander and set your strategy through the API.

Manage sales and Transaction Assurance messages

After you sell a domain, you can submit or correct your transfer authorization code for the Transaction Assurance team. You can also answer Transaction Assurance questions and messages through the Portfolio API.

Bring demand signals into your dashboard

Demand signals help you spot changes in buyer interest across your portfolio. We use them in NameFind to help review pricing, and now you can get similar metrics through the Portfolio API.

Leads: the number of inquiries for a domain, so you can see which names are drawing attention.

GoDaddy searches: how often people search for a domain on GoDaddy. Available to eligible Discount Domain Club Pro members.

Lander views: how many times people visit a domain’s lander, so you can see how much traffic each name gets.

Use these signals to decide which names deserve your attention and when to reprice.

While many of these actions and signals are also available through the Afternic website, the Portfolio API helps you review and manage them faster, more consistently, and in line with your own workflow.

Who is the Portfolio API for?

The Portfolio API is built for sellers who want to manage their listings at scale, but it’s not for everyone. It works best if you manage a large portfolio and regularly add, edit, or review hundreds of listings.

You should also be comfortable building your own integration, working with a developer, or using AI coding tools to create your workflow. The Portfolio API can change live Afternic listings, so start with read-only checks, grant only the access your workflow needs, and make sure you know how to revoke access before turning on any workflow that makes changes.

If you manage a smaller portfolio or prefer a guided experience, Portfolio Agent may be a better place to start. Available from your Afternic dashboard for sellers with 500 domains or fewer, Portfolio Agent offers conversational domain management and lets you edit up to 500 domains at a time.

How to set up Portfolio API

To bring Afternic portfolio work into your own dashboard, integration, script, or AI-assisted workflow, start by creating an API key in your Afternic account.

Open your account profile. Go to your Afternic account profile, scroll down to API keys, and select Add Key.

Name your key. Enter a name you’ll recognize, such as “Portfolio dashboard.” Then save the API key and secret key somewhere secure.

Set up your connection. Enter your keys in your integration’s secure credential settings. If you’re using an AI coding assistant to help build a dashboard or workflow, share the API documentation and describe what you want the workflow to do. Use placeholder credentials while building, then add your real keys only through secure settings.

Start with a simple check. Retrieve your listings and confirm they match your portfolio before you turn on any workflow that can make changes.

Keep API keys out of chat prompts, shared documents, or public code. API access can authorize live pricing and listing changes, so review permissions carefully, and protect your account with two-step verification.

For setup details, supported actions, and usage limits, read the Afternic Portfolio API documentation .

Buy, manage, and sell through connected tools

Opening Afternic Portfolio API access is another step toward giving domain investors more control over their domains, with less manual work across GoDaddy’s buy, manage, and sell ecosystem.

Buy. GoDaddy Auctions has opened API access for bidding on expired domain auctions and purchasing closeouts. Explore the Auctions API.

Manage. The GoDaddy Domains v3 API lets you register domains and manage names in your GoDaddy portfolio.

Sell. The Afternic Portfolio API brings listing management and portfolio information into your connected workflows.

Together, these APIs give investors more ways to connect the work of acquiring, managing, and selling domains in the tools they already rely on. With the right integrations in place, you can build workflows around the full journey of a domain in your portfolio, from acquisition to sale.

Get started

Pick a first workflow that fits how you manage your portfolio, such as checking listing consistency, adding new acquisitions, or reviewing demand signals. Start with one useful task, then expand as you decide where more control and less manual work can make the biggest difference.

Follow our Portfolio API setup guide to prepare your connection, understand permissions, and work through a first example. If you’re building an integration, the Portfolio API documentation has the technical reference.

Happy selling!
