Platform / Business Rules

Make sure your APIs return the right answer.

Your APIs need to deliver the correct data in every scenario. Catch misconfigurations and align applications with internal and external business rules so your API stays the source of truth.

Rules that match your business

Validate business logic, not just status codes.

APIContext checks whether APIs return the right information for real scenarios: pricing, eligibility, compliance, routing, regional behavior, and other rules unique to your business.

Unique to your business

Define the rules your APIs must always follow.

Every business has its own policies, products, prices, regulatory requirements, and edge cases. Business rule checks make sure APIs deliver the right information, not merely a successful response.

Fix misconfigurations easily

Turn every variance into a fast triage decision.

When APIContext finds a variance, teams can review the evidence, decide whether to update the API, change the application, or revise the rule, then get the right owner involved.

Right alert, right team

Alert the right team to conformance issues - not SRE

Business rule conformance issues are not generic application monitoring noise. Deliver alerts at the right cadence to compliance, architecture, product, or engineering teams.

Alert by rule ownership and severity
Control cadence so teams are not overwhelmed
Separate compliance issues from infrastructure incidents
