# Sinch Available Number API **Canonical:** https://apis.io/apis/sinch/sinch-available-number-api/ **Provider:** Sinch — https://apis.io/providers/sinch/ **Base URL:** https://us.conversation.api.sinch.com **Documentation:** https://developers.sinch.com/docs/conversation/api-reference/conversation Sinch Available Number API is one of 101 APIs that [Sinch](https://apis.io/providers/sinch/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification and an AsyncAPI event-driven specification. This API exposes 73 JSON Schema definitions. Tagged areas include Available Number. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, an AsyncAPI specification, and 73 JSON Schemas. You can use the Available Number API to search for numbers that are available to buy, in any region and of any number type, and to check a specific number's availability, price, and capabilities. To buy a number you found, use the [Number Order](https://developers.sinch.com/docs/numbers/api-reference/numbers/number-order) API. **Deprecated:** The activation endpoints in this API, "Activate a new phone number" and "Rent any number that matches the criteria", are deprecated and only support US `LOCAL` numbers. They remain available for existing integrations, but new integrations should use the [Number Order](https://developers.sinch.com/docs/numbers/api-reference/numbers/number-order) API, which supports numbers from all regions and of all number types. ## Operations (4) | Method | Path | Summary | |---|---|---| | POST | `/v1/projects/{projectId}/availableNumbers/{phoneNumber}:rent` | Activate a new phone number | | POST | `/v1/projects/{projectId}/availableNumbers:rentAny` | Rent any number that matches the criteria | | GET | `/v1/projects/{projectId}/availableNumbers` | Search for available phone numbers | | GET | `/v1/projects/{projectId}/availableNumbers/{phoneNumber}` | Search for a specific phone number | ## Machine-readable artifacts (107) -
