Postman's marketing headline "AI is powered by APIs. APIs are powered by Postman." is effective for these reasons:

• Creates a clear logical chain that positions Postman as a fundamental service to AI development (all the rage right now)

• Uses repetition of "powered by" to create a memorable structure and emphasize Postman's important role

• Establishes relevance to cutting-edge technology (AI) while highlighting Postman's core focus (APIs)

• Simple, declarative sentences convey authority and confidence

• Avoids overly-technical jargon while still speaking directly to developers

• Ultimately positions Postman as the foundation that enables modern technology
