Introduction

What Model Gate is, how cost and usage cost differ, and which API formats are supported.

Model Gate is an AI gateway with OpenAI-compatible and Anthropic-compatible APIs. One API key can use every model enabled for that account.

Workflow

Create an API key in the control panel.
Fund the Model Gate account balance.
Select a canonical model ID or enabled alias.
Send the request to https://api.model-gate.com.
Model Gate resolves the route and forwards the canonical model upstream.
The actual request cost is debited from the account.
The key and group usage limits are updated with the independently calculated usage cost.

Cost and usage cost

cost is the actual balance debit.
usage_cost affects only resettable API-key and group limits.
official_base_cost is the request cost at saved official provider rates.

The effective usage rule is configured on the key or inherited from its group.

Supported API formats

Format	Base URL	Main endpoint
Anthropic	`https://api.model-gate.com`	`POST /v1/messages`
OpenAI	`https://api.model-gate.com/v1`	`POST /v1/chat/completions`
OpenAI Responses	`https://api.model-gate.com/v1`	`POST /v1/responses`

See the endpoint reference and connection guides.

Account workspace

The authenticated Dashboard separates the range selector and refresh controls from usage metrics. Large counters have compact labels and an exact value alongside them. Spend and, for Individual accounts, Tokens charged refresh from the same aggregate snapshot. Empty ranges, stale data and aggregate delays are distinguished; a range without requests has no success-rate percentage. The token-category mix describes the displayed token counters and is not a cache-hit ratio.

Eligible Individual accounts can receive a one-time channel subscription reward when the offer is configured. The shared account banner displays the current amount (default USD 1), links to Profile and remains visible until the current channel reward has been claimed. Connect Telegram, join the configured channel and use the claim action; channel membership is verified before crediting. Previously granted rewards are not reissued when the configured amount changes. Business accounts do not use Telegram account binding or this reward.

Support replies in your account

A small notice above account content links to Support when a conversation has an unread staff reply. The count is the number of tickets, not individual messages. Open the ticket to acknowledge the messages displayed there; viewing the ticket list does not clear the notice. A visible account page refreshes its count about once a minute. Historical conversations from before read tracking was introduced are not re-announced automatically.
