Anthropic-compatible headers

anthropic-version: 2023-06-01
Content-Type: application/json

For Anthropic SDKs, set the base URL to https://api.logicc.cloud/anthropic. The SDK appends its messages path to that base URL.

5. Model discovery and availability

GET https://api.logicc.cloud/v1/models returns the models enabled for the authenticated key. This response is authoritative. A model shown in the price list may still require activation for a specific key.

To request a model, email [email protected] with the subject API and include the exact API identifier.

Credential handling

Store API keys in a server-side secret manager or environment variable. Never expose a key in browser code, mobile applications, public repositories, logs, screenshots, or support emails.
