📊 Current catalog

Nexus displays current available models, prices, usage formats and verified API capabilities.

⚖️ Pay for actual usage

Depending on the model, pricing can be based on input and output tokens, supported cache components or a fixed price per successful request.

If required usage data cannot be determined reliably, Nexus does not apply a hidden later backcharge for that request.

📱 Telegram dashboard

On first launch, the user selects the interface language and display currency. The profile is then created automatically and a public Nexus ID is shown.

The dashboard provides:

• balance top-up and purchase activation;
• API key creation and configuration;
• model and spending-limit management;
• history;
• support;
• transfer of available positive balance between your own profiles;
• referral program;
• English and Russian interface;
• amount display in RUB, USD, EUR and CNY.

❗ Important information

Nexus API is a usage-based API service with a prepaid balance. It is not ChatGPT Plus, Claude Pro, a subscription to a specific third-party service or an unlimited plan.

🧠 Models and compatibility

Nexus provides technical compatibility with selected third-party API formats and client applications.

References to Claude, Anthropic, OpenAI, ChatGPT, Codex, Gemini, DeepSeek, GLM and other brands do not imply official partnership, endorsement or ownership.

Nexus is not a complete replacement for every feature of every official API.

Available models and features depend on the specific API key and may change.

💰 What “up to 20x better value” means

The comparison applies to selected models and compares Nexus pricing with the current official API pricing of the corresponding provider.

The actual difference depends on the model, billing mode and current prices and may change.

Always rely on the current price displayed by Nexus before use.

⚖️ Balance and billing

Nexus accounting is performed in RUB.

USD, EUR and CNY can be selected as display currencies.

Multiple API keys under one profile use the same shared balance.

Depending on the model, pricing may use tokens, cache components or a fixed price per successful request.

If required usage data is missing or contradictory, Nexus does not apply a hidden later backcharge for that request.

🧪 Free trial

A free trial is available only when the corresponding feature is shown to a new user in the Telegram bot.

The test key is short-lived and is subject to the conditions displayed by the bot.

💳 Purchase and activation

If a valid Nexus ID is entered during purchase, the purchase is associated with that profile. Purchases made without a Nexus ID are activated with a one-time code received after payment. The code can only be used once.

If the wrong Nexus ID was entered or a payment requires manual review, contact support and provide the order number or transaction ID.

Never send your API key, full prompt, card details or project secrets.

🔐 API key security

Your API key is a secret.

Store it in an environment variable, keychain or secret manager.

If you suspect exposure, revoke the key immediately and issue a new one.
