Paystack wants your next airtime top-up to happen inside ChatGPT — no app, no browser

With an experimental product called Index, Paystack is letting Nigerians pay for airtime, transfers and Chowdeck orders by asking an AI agent — an early bet that the checkout button itself is about to disappear.

Shola Akinlade has watched a slow migration that most people never noticed. “If you take a step back and compare the number of people using their browser for commerce, and now introducing agents for discovery,” the Paystack chief executive told Techpoint Africa, “you’ll see that agents are coming up and browsers are going down.” The address bar, in other words, is quietly dying. Paystack’s answer is to meet buyers wherever they end up instead — and increasingly, that is inside a chat window.

That answer has a name. On 25 June, Paystack — the Nigerian payments company Stripe bought for around $200 million in 2020, now operating under the holding company The Stack Group — launched an experimental product called Index. It lets people in Nigeria complete everyday transactions by instructing an AI assistant. Ask Claude, ChatGPT or the newer OpenClaw to buy ₦1,000 of airtime, send money through Paystack’s Zap wallet, or order dinner on Chowdeck, and Index does the rest. It is live now, in a controlled early-access beta, opening first to existing Zap users.

What sits between the chatbot and your money

The interesting engineering is in what Index refuses to do. It is not an AI that wanders off to spend your money on its own judgment. Paystack describes it as a connection layer: the AI agent handles the conversation, Index interprets the request, checks that it is a supported action, confirms the permissions and limits the user has set, and only then routes the transaction to the right merchant through Zap and Paystack’s existing payment infrastructure. Crucially, Index stores no card numbers, CVVs, PINs or bank credentials — the money still moves over the same rails Paystack already runs, with the human approving each authorised payment.

That design choice matters more than it first appears. The nightmare scenario for agentic commerce — an over-eager model draining an account or picking a merchant nobody asked for — is exactly what Paystack has walled off. Merchant selection weighs the user’s stated intent, availability and delivery context rather than letting the model free-associate. The company is deliberately starting with dull, repeatable errands: airtime, data, transfers, a Chowdeck order. Food is the most complex flow it currently supports, and even that follows a predictable path. This is agentic commerce with the training wheels bolted on, and that is the point of a beta.

Why Lagos, and why now

The timing is not arbitrary. A Google-Ipsos survey Paystack cites found that 88 percent of Nigerians polled had used generative AI in the previous year, and 62 percent had used it for ordinary tasks such as planning trips or meals. When most of your customers are already talking to a chatbot daily, letting them pay from inside that conversation is less a leap than a logical next step.

Here is the shift worth watching, and it is our read rather than Paystack’s claim: for two decades, African businesses have fought to be found on search engines, social feeds and marketplace apps. If Index and products like it take hold, a new and stranger battleground opens — visibility inside an AI agent’s workflow. Being the merchant an assistant reaches for when a user says “order me lunch” could become as valuable as ranking on the first page of Google once was. Akinlade himself flags this as the signal he is hunting for: whether Index becomes “a meaningful new way for merchants to be discovered, selected, and paid through AI agents.”

That is also why a payments company, rather than a chatbot maker, may be well placed to define the rules. The frontier models are built in California; the checkout rails, the wallet and the merchant relationships in this equation are Nigerian. Index is the first public product from TSG Labs, the group’s venture studio, and the team is candid that it is running an experiment — measuring whether AI-led buying becomes a habit, which tasks people return to, and what safeguards African markets need “from the beginning.” Expansion to more merchants, billers, features and other African countries is promised, but paced to what the beta teaches. For now, the ambition is smaller and sharper than the headlines about autonomous AI shoppers: prove that a Nigerian can top up their phone by asking, and that the money moves safely when they do.
