In SaaS and API products, a feature evaluation is the runtime check that decides whether a user or account can access a capability based on plan, billing state, and current usage.
It links pricing rules to product behavior by enforcing limits, gating access, and recording usage for billing and revenue reporting, reducing gaps between what was paid for and what is available.
When a user action triggers a protected endpoint, the app sends Schematic inputs like plan, role, workspace, request context, and current usage to evaluate entitlements.
Feature evaluation runs during the request, returns an access decision or limit-enforcement result, and may write back a state update like usage increments or credit decrements for billing-aligned behavior.
Understanding the characteristics below helps clarify how feature evaluations are expressed in product behavior across accounts, users, and requests in SaaS and AI systems.
A decision commonly resolves to allow, deny, or allow-with-constraint states that surface as UI gating, API error responses, or conditional workflow steps in SaaS and AI products.
Inputs typically include account identifiers, user role, workspace, environment, request attributes, and current counters, appearing in multi-tenant SaaS routing, API middleware, and model-invocation request handlers.
Limits are represented as quotas, rate ceilings, seat caps, or credit balances, and they commonly appear as per-workspace quotas for actions, per-user seat checks, or per-project token budgets in AI products.
Many systems capture a trace of inputs, decision, and applied constraints, appearing as entitlement logs in admin consoles, support tooling views, and compliance-oriented histories tied to account activity.
Feature evaluations help users experience a product that matches their account context, with access and limits that stay consistent across screens, workflows, and requests as their needs change over time.
Clearer expectations about what is available before a user commits time to a workflow
Fewer confusing dead-ends when an action is blocked by plan, role, or account state
More predictable behavior across web UI and API surfaces when capabilities are gated
Faster self-service troubleshooting when constraints are surfaced as specific reasons instead of generic failures
Smoother transitions during plan changes, add-ons, or renewals without shifting product behavior mid-task
Schematic acts as a centralized monetization system that evaluates feature-related entitlements using pricing, subscriptions, usage, access, and billing-state signals as inputs to a consistent decision surface for the product.
At a systems level, Schematic holds the entitlement model that represents plan rules, add-ons, seat and credit constraints, and role-aware access boundaries, then applies those rules whenever the product needs an execution-time authorization or limit decision tied to the current account state.
Schematic also maintains the state needed for enforcement, including usage and credit consumption, so that evaluations can incorporate up-to-date counters and balances without scattering billing-aligned logic across multiple services.
Because Schematic continuously reflects subscription and billing-state changes into the entitlement layer, evaluations remain aligned with upgrades, downgrades, renewals, and cancellations while leaving payments and invoicing responsibilities outside the product runtime.
Feature evaluation can be applied to any capability gated by plan, usage, role, or account state, including API endpoints, UI elements, quotas, and premium add-ons.
No, feature evaluation is used for both free and paid plans to enforce access, usage limits, and feature availability according to each plan’s rules.
Feature evaluation cannot address issues outside entitlement logic, such as product bugs, payment processing errors, or external system outages.
