# American Express Commits to User Protection in Agentic Commerce American Express has developed a developer kit to verify agents registered with the company for handling transactions. Luke Gebb, executive vice president and head of global innovation at American Express, stated that the agentic commerce space has yet to figure out what to do with the risk of AI agents not carrying out tasks as intended.

Gebb noted that American Express's existing dispute resolution processes could support verification in agentic commerce.

An American Express spokesperson stated that the developer kit will reduce customer disputes and chargebacks because the kit only gives payment credentials to verified agents, and Amex will authenticate card members before allowing them to use agents, thereby giving merchants a stronger baseline of legitimacy.

Gebb told Fortune that to date there have probably been as many press releases on agentic commerce as transactions, but no doubt it will happen. com reported on these developments during discussions at an event marking 25 years of Fortune Brainstorm Tech.

Infrastructure Releases by Payment Companies Mastercard released infrastructure in the agentic commerce sector over the past several months.

Visa released infrastructure in the agentic commerce sector over the past several months. Stripe released infrastructure in the agentic commerce sector over the past several months. These releases indicate growing activity in agentic commerce, where AI agents handle transactions.

Gebb said that when asked about the cost to American Express of protecting against AI errors, agents will improve over time, and if consumers have the confidence to transact using agents on the Amex network, that will ultimately bring more transaction volume to the company.

American Express Views on Stablecoins Luke Gebb said American Express has a variety of plans surrounding stablecoins, which he sees as useful more for settlement than for payments, but declined to go into specifics.

This perspective aligns with broader explorations in payment technologies. The company's focus on agent protection complements these plans by addressing immediate risks in emerging commerce models.
