Inzinx
Eligibility & pricing rules engine

Change what qualifies — and know exactly why — without waiting on a deploy.

Inzinx lets your team define eligibility and pricing as versioned, visual rules — not application code buried in a deploy. Draft, validate, and activate changes safely, then call one API to evaluate and rate in real time.

Visual rule builder
Build eligibility logic — AND/OR/NOT condition trees — with a drag-and-drop builder, then see it as an interactive flowchart. Rules that reference other rules expand inline, so composed logic stays readable. No code, no redeploy.
Ordered pricing pipelines
Chain flat adjustments, conditional factors, table lookups, tiered brackets, and deductible curves into a reorderable pricing pipeline that applies in exactly the order you define — five factor kinds, not a lowest-common-denominator one.
Composable, versioned, tabular
Rules can reference other rules instead of duplicating logic, rate tables are their own versioned entity you can reuse across rules, and every rule/rating-rule/table keeps its full draft → active → archived history — nothing is ever silently overwritten.
Safe, atomic activation
Drafts are validated as a whole set before going live — activation either fully succeeds or changes nothing. Never half-broken.
Start free, scale as you grow
Every account gets 3 months free with a daily quota. Upgrade whenever you need more evaluate/rate calls — no long-term contract.
Full evaluation trace, every call
Every eligibility and rating decision comes with a complete trace of exactly how it was reached — not just a debugging aid, but the audit trail regulated industries need to justify a result after the fact.

See the logic, not just the result

Nested AND/OR/NOT conditions, and rules that reference other rules, render as an interactive flowchart — so a policy nobody's touched in a year is still readable at a glance, not just runnable.

A real rule's visual view — premium-eligibility references a shared resident-adult rule, expanded inline.

Frequently asked questions

›What is Inzinx?

A rule engine for eligibility and pricing decisions. Instead of hardcoding "who qualifies" and "what it costs" into your application and redeploying every time a business rule changes, you define both as versioned, visual rules in Inzinx, then call one API to evaluate eligibility or compute a price in real time. Every call returns a full trace explaining exactly why it reached that result -- not just the answer.

›Do I need to know how to code to use it?

No. Rules are built with a visual, drag-and-drop condition-tree editor (AND/OR/NOT logic, comparisons, table lookups, tiered brackets) directly in your dashboard, and every eligibility rule can also be viewed as an interactive flowchart. If you do need something the visual builder can't express, you can drop into a raw scripted expression for that one condition -- but it's never required.

›Is there a free plan?

Yes -- every new account gets 3 months free with a daily quota for both management calls (submitting/activating rules) and evaluation calls (evaluate/rate). No credit card is required to sign up.

›Is my data safe?

Rules, data, and API keys are isolated per account (tenant). API keys are stored as one-way hashes, never in plain text; passwords are hashed with bcrypt. Login supports optional two-factor authentication (TOTP/Google Authenticator) plus automatic lockout after repeated failed attempts. See our Security page for the full picture, including independent external testing (SSL Labs, OWASP ZAP, Greenbone/OpenVAS) and how to report a vulnerability.

›Can I integrate Inzinx directly into my own application?

Yes -- once you're signed up, generate your own API keys from Dashboard → API keys (separate from your login, one for each integration you run). See our Developers page for the full REST API reference: authentication, request/response shapes, and worked examples.
