Postman runs Agent Mode for 40 million developers on Amazon Bedrock

Postman's Agent Mode is a portal for working across API testing, documentation, discovery, and implementation in an AI-native way. Postman has evolved over 11 years, and developers and users learned to locate information by expanding sidebars, checking tabs, and opening requests. The team built dedicated context handlers that distilled each entity into what the agent needed to know, because serializing the existing interface data model did not produce useful context.

Two other patterns came out of that work. The architecture selects tools based on need and context and isolates individual execution threads, so the model sees only the tools relevant to the current task. For products such as the API Catalog, Postman consolidated multiple narrow views into a single query tool that can generate complex queries with joins and WHERE clauses, shifting the engineering job from building one tool per question to modeling the data well once.

On Amazon Bedrock, Postman gains model flexibility across supported Anthropic Claude models, cross-Region inference for throughput, model-dependent zero data retention, and multi-tier prompt caching. Postman's production implementation is proprietary and is not available as a public sample repository.
