Every capability is exposed here, key-authenticated and rate-limited; the web app is a client of the same platform. **Authentication** — pass your workspace API key on every request (except the API description) as `Authorization: Bearer loice_sk_…`. Keys are created under Settings → API Keys. **Billing** — operations are billed in points against your workspace balance. Each operation below states when the charge applies. The current cost of every operation is shown in the app under [Settings → Billing](https://app.loice.ai/settings/account?tab=billing) and in the live API description, `GET /api/v1/openapi.json`. Calls that fail because of a system or provider error (timeouts, upstream failures, our defects) are not billed, and rate-limited calls are rejected before any billable work. Check headroom with `GET /api/v1/points`. Where an operation documents an `Idempotency-Key` header, send one to retry safely: a repeated request returns the original outcome and is not charged again. **Errors** — every non-200 response has the shape `{ "error": { "message": "…" } }`. Operations whose error responses document an `error.code` also return that machine-readable code beside the message; branch on the code, not the text. servers: - url: https://app.loice.ai security: [] paths: /api/v1/lead-lists: get: summary: List lead lists description: >- Returns one page (25) of the workspace’s active lead lists, most recently changed first, each with its member, verified-email, mobile and CRM-sync counts. #### Billing Free — this endpoint does not consume points. parameters: - schema: type: integer minimum: 1 maximum: 100000 default: 1 description: 1-based page; 25 lists per page. required: false description: 1-based page; 25 lists per page. name: page in: query - schema: type: string maxLength: 120 description: Search by list name. required: false description: Search by list name. name: q in: query responses: '200': description: One page of lists. content: application/json: schema: type: object properties: data: type: array items: type: object properties: id: type: string name: type: string description: type: string owner: type: - object - 'null' properties: id: type: string name: type: - string - 'null' required: - id - name crmAutoSync: type: boolean archived: type: boolean createdAt: type: string updatedAt: type: string stats: type: object properties: members: type: integer withEmail: type: integer verifiedEmail: type: integer description: >- Members whose email the workspace holds with status `valid`. withMobile: type: integer crmSynced: type: integer crmFailed: type: integer required: - members - withEmail - verifiedEmail - withMobile - crmSynced - crmFailed required: - id - name - description - owner - crmAutoSync - archived - createdAt - updatedAt - stats meta: type: object properties: page: type: integer pageSize: type: integer description: Always 25. total: type: integer pageCount: type: integer crmConnected: type: boolean required: - page - pageSize - total - pageCount - crmConnected required: - data - meta example: data: - id: cmf3x0v2b0001abcd name: Fintech CFOs description: '' owner: null crmAutoSync: false archived: false createdAt: '2026-10-15T09:00:00.000Z' updatedAt: '2026-10-15T09:30:00.000Z' stats: members: 42 withEmail: 30 verifiedEmail: 28 withMobile: 0 crmSynced: 0 crmFailed: 0 meta: page: 1 pageSize: 25 total: 1 pageCount: 1 crmConnected: false '400': description: '`validation_error`: a query parameter is invalid.' content: application/json: schema: type: object properties: error: type: object properties: code: type: string enum: - validation_error - unauthenticated - not_found - forbidden - method_not_allowed - idempotency_conflict - idempotency_in_progress - rate_limited - internal_error - run_already_active - run_already_continued - search_unavailable - invalid_continuation - invalid_input - insufficient_credits - incomplete description: >- Machine-readable error code.
