New capabilities highlighted at POST/CON 25 give developers the tools to lead with APIs in an AI-driven world
LOS ANGELES–(BUSINESS WIRE)–POST/CON — Postman, the world’s leading API collaboration platform, today announced new capabilities that make it dramatically easier to design, test, deploy, and monitor AI agents and the APIs they rely on. Unveiled at the company’s annual user conference POST/CON, these advancements include Postman Insights now in open beta, major enhancements to the Postman API Network, and new features to strengthen collaboration.
As the AI wave accelerates, Postman’s internal data paints a clear picture: developers aren’t just experimenting with LLMs; they’re operationalizing real systems built on APIs.
Based on anonymized, aggregated data from the Postman API Platform between May 2023 and April 2025:
- Meta’s Llama traffic grew 7x, driven by the rise of open-weight, fine-tuned models.
- Google Gemini grew 5x, as orchestration-ready models gained traction with enterprise teams.
- Replicate and Mistral saw traffic double and quadruple respectively—reflecting increased adoption of customizable, infrastructure-flexible models.
- OpenAI still accounts for 60% of AI-related traffic—but the trend is diversification, not consolidation. Developers are choosing more models and calling more APIs.
While hype for LLMs continues to grow, agents are still unreliable in production and require rigorous evaluation both before and after deployment. Engineering teams are realizing that testing, governance, and observability must catch up to the complexity of these intelligent systems. Reliable agents require more than model evaluation—they need high-quality, discoverable APIs they can trust.
Postman is used by more than 40 million developers and 500,000 organizations around the world. Now with its new agentic AI capabilities, Postman becomes the platform of record for building intelligent, API-driven systems with production-grade observability, agent-ready tooling, and scalable onboarding.
Key new capabilities highlighted at POST/CON 2025 include:
- Postman Insights: Real-time observability for APIs—track usage across endpoints and versions (human and agent), detect failure patterns, and proactively resolve issues before they reach users.
- Simplified Testing with Repro Mode in Insights: Reproduce API failures instantly using real-world headers, payloads, and authentication tokens—perfect for debugging agent interactions in production.
- Agentic AI Builder + Model Context Protocol (MCP) Integration: Instantly turn APIs into callable agent tools using the MCP, generate MCP servers directly from collections, and test agent behavior with a new first-class MCP request type.
- World’s First MCP Server Network: Discover, test, and adopt agent-compatible endpoints at scale in the world’s first curated network for MCP Servers, now hosted on the Postman API Platform. Verified publishers can self-publish trust tools for agents, making it simpler and faster than ever for developers to discover reliable servers and reduce security risk.
- Enterprise-Ready Workflow Integrations: Accelerate API delivery and reduce cycle time with seamless integrations across GitHub (real-time collection sync, branch-based governance), Jira (context-aware issue creation and tracking), and Slack/Microsoft Teams (improved notifications for team-wide visibility). These capabilities help teams stay aligned, resolve issues faster, and ship APIs with confidence, at enterprise scale.
These new platform capabilities go hand-in-hand with the API Network’s reach and reliability—giving teams everything they need to build and operationalize AI agents at scale.
- Notebooks for Developer Onboarding: Accelerate time to value with immersive, interactive guides that combine documentation, tutorials, and live API calls—turning API exploration into instant execution. Notebooks reduce onboarding friction, boost adoption, and help teams scale usage faster.
- Activity Feeds + Watchers: Drive adoption and reduce breakage by keeping every API consumer—human or agent—instantly in sync. With real-time changelog alerts, versioning updates, and integrated chat notifications, teams ensure reliable consumption, lower support burden, and faster iteration across the API lifecycle.
“These new tools position Postman as the first unified platform to operationalize agentic AI systems safely, reliably, and at scale—bridging the gap between the promise of LLMs and the production requirements of modern software,” said Abhinav Asthana, Co-founder and CEO of Postman. “Agent-based systems aren’t just clever prompts—they’re full systems that must be tested, debugged, and governed like real software. Postman is where you build that intelligent system with trust, transparency, and speed.”
Postman’s API Network, home to over 18,000 publishers and 100,000+ APIs, is the foundation for agent adoption. It ensures both humans and agents can find, authenticate, and safely interact with live, production-ready APIs—whether public, private, or partner-facing.
“We’re accelerating in the agentic commerce era,” said Alex Chriss, President and CEO of PayPal. “The Postman API Network gives our developers powerful tools to make it easier than ever to build, test and scale AI-powered commerce experiences. It’s not just speed—it’s developer velocity that translates into real value for customers.”
