# Use cases

> Common Seamless API integration patterns for enrichment, CRM sync, webhooks, and AI sales automation.

These recipes show complete, runnable patterns on top of the public v1 REST API. Each guide assumes you have an [API key](/authentication/api-keys) and understand [identifiers](/understand-identifiers-and-request-flow).

| Pipelines, ETL, Postman, backend services | REST API guides on this tab                             |
| Cursor, Claude, ChatGPT, no-code agents   | [MCP quickstart](/mcp/quickstart)                       |
| Both                                      | REST for data movement; MCP for interactive prospecting |

<Note>
  The [API Reference](/reference/searchcontacts) tab documents every endpoint. These use cases show how to chain them for real workflows.
