Keys are scoped to a firm and an access tier. ## Access Tiers | Tier | Description | |------|-------------| | `read_only` | GET endpoints — read data without mutation | | `standard` | read_only + create/update case referrals | | `full` | standard + delete, routing rules, bulk import, firm mutation | ## Rate Limiting Rate limits are enforced per API key. Exceeded limits return `429 Too Many Requests`. ## Pagination List endpoints accept `page` (default 1) and `limit` (default 20, max 100) query params. ## Response Format Successful responses are wrapped in `{ data: T, meta: { requestId, timestamp } }`. Errors are wrapped in `{ error: { code, message }, meta: { requestId, timestamp } }`. contact: name: CaseXchange API Support url: https://casexchange.com servers: - url: https://api.casexchange.com/api/public/v1 description: Production Public API base path - url: /api/public/v1 description: Relative base path (for proxied docs/local environments) security: [] tags: - name: Reference Data description: Case types, jurisdictions, and counties - name: Firms description: Firm directory and profile management - name: Cases description: Case referral lifecycle and actions - name: Sent Cases description: 'Sender-side case management: create, track, and refer/route cases you own' - name: Documents description: Document upload, download, and management - name: Users description: User management within the caller's firm - name: Routing description: Referral routing rules - name: Analytics description: Dashboard and case analytics - name: Notifications description: Notification preferences and email management - name: Med Cases description: Med Xchange cases and their nested referrals to medical providers - name: MedEx Documents description: Med Xchange case document listing and download - name: Import description: Bulk case import/update via CSV - name: Salesforce description: Org-facing endpoints consumed by the CaseXchange managed package paths: /sent-cases: get: tags: - Sent Cases summary: List sent cases description: >- Paginated list of cases owned by the caller's firm, each with its most-recent referral. operationId: listSentCases parameters: - in: query name: page schema: type: integer default: 1 minimum: 1 description: Page number (1-indexed) - in: query name: limit schema: type: integer default: 20 minimum: 1 maximum: 100 description: Results per page (max 100) - name: status in: query schema: type: string description: Filter by CaseStatus - name: closingStatus in: query schema: type: string description: Filter by ClosingStatus - name: search in: query schema: type: string description: Reference number or receiving firm name - name: sort in: query schema: type: string enum: - updatedAt - status - referenceNumber - in: query name: order schema: type: string enum: - asc - desc responses: '200': description: Sent cases list content: application/json: schema: type: object properties: data: type: array items: $ref: '#/components/schemas/SentCaseListItem' pagination: $ref: '#/components/schemas/Pagination' meta: type: object properties: requestId: type: string example: req_f2dbe1d3f6ad4a7bb5b4c9f2 timestamp: type: string format: date-time required: - requestId - timestamp required: - data - pagination - meta '401': description: Invalid or missing API key content: application/json: schema: type: object properties: error: type: object properties: code: type: string message: type: string required: - code - message meta: type: object properties: requestId: type: string example: req_f2dbe1d3f6ad4a7bb5b4c9f2 timestamp: type: string format: date-time required: - requestId - timestamp required: - error - meta '403': description: API key tier does not permit this action content: application/json: schema: type: object properties: error: type: object properties: code: type: string message: type: string required: - code - message meta: type: object properties: requestId: type: string example: req_f2dbe1d3f6ad4a7bb5b4c9f2 timestamp: type: string format: date-time required: - requestId - timestamp required: - error - meta security: - apiKeyAuth: [] components: schemas: SentCaseListItem: type: object properties: id: type: string format: uuid referenceNumber: type: string nullable: true salesforceId: type: string nullable: true receivingFirmName: type: string nullable: true receivingFirmId: type: string format: uuid nullable: true status: type: string description: CaseStatus enum value closingStatus: type: string nullable: true updatedAt: type: string format: date-time Pagination: type: object properties: page: type: integer limit: type: integer total: type: integer totalPages: type: integer securitySchemes: apiKeyAuth: type: apiKey in: header name: X-API-Key description: Public API key (starts with cxp_).
