Postman’s latest release brings a comprehensive checklist and developer guide aimed at helping teams build AI‑ready APIs that serve the next generation of machine‑learning models. The core message is simple yet powerful: the performance of even the most sophisticated AI systems is limited by the quality of the data they ingest, and that data arrives through your API endpoints. Inconsistent, unclear, or unreliable endpoints force models to spend valuable compute on data cleaning instead of delivering real value.
The guide breaks down the checklist into actionable categories—endpoint design, data validation, documentation, testing, security, and versioning. For example, it recommends adopting a single, versioned schema for every resource, enforcing strict JSON schema validation at the gateway, and publishing OpenAPI specifications that include example payloads and error codes. It also stresses the importance of automated contract tests, continuous monitoring of response latency, and graceful degradation through circuit breakers, all of which help preserve model accuracy in production.
Implementing these practices may seem daunting, but Postman’s tools make the transition straightforward. By integrating the checklist into your CI/CD pipeline and leveraging the Postman Collection Runner, you can automatically run contract tests against every new release. Measuring key metrics—response time, error rate, and data consistency—provides a clear view of how API quality translates into model performance. Ultimately, a robust, well‑documented API reduces the time AI developers spend on data wrangling, allowing them to focus on building smarter, faster models.
