Nexus API — Claude Code, Codex, Cursor, GPT | API balance, up to 20x value

Description

This is an API balance top-up billed per request. It is not a subscription and not a ready-made account. After payment you receive balance in the accounting currency, RUB. Units equal the credited amount in RUB: 1 unit = 1 RUB. You issue the API key yourself in the Telegram bot. The order does not include a ready-made key or a ChatGPT or Claude account. How the purchase is credited If you entered a valid Nexus ID at checkout, the balance is credited to that profile automatically. No activation code is needed. If you left Nexus ID empty, you receive a one-time activation code like NXP-... and a bot link after payment. Open the link from the message (/start pay_) or, in the bot, choose Top up → Redeem code and send the code. The 16-digit Digiseller order number is not the code. The code is accepted once. Next steps 1. Open the bot: https://t.me/nexus_hubbot 2. On first launch, choose the interface language and display currency. The bot creates a profile and shows a public six-digit Nexus ID. 3. After the credit, open Keys → Issue a key. The key is shown once. 4. Connect the key and base URL in your client. See “How to use” and the docs. Who this is for For Claude Code, Codex CLI, Cursor, and for integration into custom apps, automations, and chat bots via OpenAI-compatible, Anthropic-compatible, or Gemini-compatible APIs. Nexus does not include a ready-made ChatGPT-style web chat. Models and prices Families in the current catalog: GPT and Codex, Claude, Gemini, DeepSeek, GLM, Grok. The set and prices depend on your API key and can change. This listing does not freeze model IDs. Check Models in the bot or https://docs.nexus-hub.ru/en/models/ Compatible base URLs - Claude Code (Anthropic Messages): https://api.nexus-hub.tech - Codex and OpenAI-compatible clients: https://api.nexus-hub.tech/v1 - Gemini-compatible clients: https://api.nexus-hub.tech/v1beta You pay for actual usage. Depending on the model, price is based on 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. A free trial exists only when the bot shows it to a new user. Conditions are on that screen. Docs: https://docs.nexus-hub.ru/en/ Status: https://status.nexus-hub.ru/

Additional information

Important Nexus API is a usage-based API service with a prepaid balance. It is not ChatGPT Plus, Claude Pro, a subscription to a third-party service, or an unlimited plan. The activation code and the API key are different. The NXP-... code only credits a purchase made without a Nexus ID. You issue the API key yourself after the credit, and you never send it to anyone. References to Claude, Anthropic, OpenAI, ChatGPT, Codex, Gemini, DeepSeek, GLM, Grok and other brands do not imply partnership or endorsement. Nexus is not a full replacement for every official API feature. Accounting currency is RUB. USD, EUR and CNY are display currencies only. All API keys on one profile share one balance. 1 “Ruble” unit = 1 RUB of Nexus balance. Buy 500 units and 500 RUB is credited. The per-unit storefront price is what you pay, not the credited face value. If a bonus applies, the bot shows it on a separate line together with the total credited. A wrong Nexus ID credits a different profile. If a payment needs review, contact support with the order number. Do not send an API key, a full prompt, card details or project secrets. Support in the bot: More → Support. If Telegram is unavailable: help@nexus-hub.tech
