Dark plum card with a centered Duffel logo and headline "The best API to sell flights online," plus a glowing node diagram linking travel apps to airline logos through a central mark.
Summary
A dark plum card centering the Duffel logo and the headline "The best API to sell flights online," with a glowing flow diagram routing travel apps through a central Duffel node out to airline logos.
Visual description
Deep purple-black background with a soft pink glow at the center. The top centers the small Duffel logo and wordmark, then an oversized two-line pale-pink headline "The best API to sell flights online." Below the headline a horizontal node diagram flows left to right: labeled boxes "Online Travel Agency" and "AI-Based Travel Assistant" feed into capsule labels "Flight Search" and "Create Order," which converge on a glowing red circular Duffel mark at center, then fan out along curved lines to a vertical stack of airline-tail logos on the right edge. The connectors glow against the dark field.
Key takeaway
The left-to-right flow diagram literally diagrams the API: requests on the left, the product as the hub, airline supply on the right. A single glowing brand node at the center makes the company the connective tissue of the whole system.
Reuse notes
Strong for an API, infrastructure or middleware product that sits between consumers and suppliers. Needs a dark field for the glow to register. The diagram carries the message, so keep node labels short and the central mark dominant.
