GET /v1/models;The bot guide is the source for user-visible menu flows.
This is an urgent correction. A CryptoBot payment could succeed while the balance stayed the same. Separately, under heavy load the API sometimes returned an internal error instead of asking the client to try again shortly. Both cases are fixed.
This hotfix follows the October 27 update. It restores top-up buttons and the confirmation shown after activating a paid purchase in the bot. In some cases the action had already been completed, but the bot showed an error or nothing at all.
The October 27 update makes it easier to top up, invite friends and contact support. It also improves bot navigation and API reliability and refreshes the client setup guides.
This hotfix restores buttons on screens the bot shows after you enter text. Previously, a button on a newly displayed screen could incorrectly say that the interface had changed and ask you to reopen the menu.
The September 25 Nexus update makes API requests easier to retry after connection failures, simplifies partner journeys, and makes Telegram messages more useful to recipients. We have also expanded capacity for model requests, so responses should arrive more consistently.
The regular Nexus update of September 4 adds the Grok family, expands familiar model lines, lowers prices for select models, moves the service to nexus-hub.tech, and makes the API more reliable.
The regular Nexus Hub update for August 20 introduces new favorable balance top-up methods (SBP, bank cards, cryptocurrency), a comprehensive visual redesign of the documentation website and public status page, improved support ticket dialogs, and seamless API compatibility with various clients.
An urgent hotfix addresses issues when closing support tickets, restores preset top-up amount buttons, enables promo code support for Digiseller, and streamlines model presentation in the Telegram bot.
The August 15 update brings together changes to the model catalog, API, Telegram bot, top-ups, support, and documentation.
A major architectural update to Nexus Hub: full transition to transparent
post-fact billing, introduction of the protective unbilled contract for
interrupted requests, audit payload redaction for privacy, and strict
alignment with official OpenAI, Anthropic, and Gemini specifications.
