# CaseXchange Public API

> Everything you need to build with the CaseXchange platform

## Build with Confidence

CaseXchange connects law firms with the referrals, routing logic, and case data they need to collaborate securely. The Public API uses **API key authentication** with tiered access levels, giving third parties a straightforward path to integration.

## Access Tiers

The Public API uses `X-API-Key` authentication with three access levels:

| Tier           | Key prefix     | Permissions                                                                       | Best for                        |
| -------------- | -------------- | --------------------------------------------------------------------------------- | ------------------------------- |
| **READ\_ONLY** | `cxp_ro_...`   | GET endpoints only                                                                | Dashboards, read integrations   |
| **STANDARD**   | `cxp_std_...`  | Read + create/update referrals                                                    | Case intake, referral workflows |
