**Canonical:** https://apis.io/apis/vicai/vicai-authentication-api/  
**Provider:** Vic.ai — https://apis.io/providers/vicai/  
**Base URL:** https://api.us.vic.ai  
**Documentation:** https://docs.vic.ai

Vic.ai Authentication API is one of 33 APIs that [Vic.ai](https://apis.io/providers/vicai/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Authentication. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and an API reference.

To initiate the authentication process, send a POST request to `/v0/token` with the payload as shown in the example below: ```json { "client_id": "VIC_CLIENT_ID", "client_secret": "VIC_CLIENT_SECRET" } ``` Here is an example of how to do this: ```bash curl -X POST https://api.us.vic.ai/v0/token \ -H "Content-Type: application/json" \ -d '{"client_id": "VIC_CLIENT_ID", "client_secret": "VIC_CLIENT_SECRET"}' ``` Upon providing a valid client ID and client secret, you should receive a response similar to the following: ```json { "access_token": "YOUR_ACCESS_TOKEN", "token_type": "Bearer", "expires_in": 3600 } ``` **Token Storage:** If you are storing the `access_token`, ensure your storage mechanism does not impose a character limit. Access tokens use JWT format and may be 530 characters or longer. For subsequent calls, use the value in `access_token` in the `Authorization` field. Here is an example: ```bash curl https://api.us.vic.ai/v0/healthCheck \ -H "Content-Type: application/json" \ -H "Authorization: Bearer YOUR_ACCESS_TOKEN" ``` The response should resemble the following: ```bash {"company":"Your Company Name","status":"PASS","version":"0.19.0"} ```
