# List contacts in a contact list

> The list and returned contacts must belong to the authenticated organization. Missing and cross-tenant list IDs return 404.



## OpenAPI

````yaml /api-reference/openapi.json get /api/v1/contact-lists/{listId}/contacts
openapi: 3.1.0
info:
  title: Nautilus Public API
  version: 1.0.0
  description: >-
    Tenant-scoped public API. Except for /api/v1/openapi.json, requests use a
    Clerk tenant API key as a Bearer token. The key's organizationId is the sole
    tenant scope; organization IDs supplied by callers are never accepted.
    Detail endpoints deliberately return 404 for both missing and cross-tenant
    records. Canonical collections use the standard envelope and endpoint-bound
    cursor pagination. Timestamps are UTC ISO 8601 values and monetary amounts
    ending in Cents are integer cents. Responses use narrow serializers and
    exclude credentials, API keys, provider configuration, access tokens,
    webhook secrets, raw provider payloads, and internal workflow or activity
    data.
