Getting started & API connection

Is the API OpenAI-compatible? Can I reuse my existing code?

Yes. The Router speaks the OpenAI protocol, and also Anthropic Messages and the OpenAI Responses API. You only switch the base URL and API key; your existing code or SDK keeps working without any refactoring.

How do I get my API key and base URL?

Log in to your HostYourAI account and go to API keys. There you create a key; the base URL is shown right next to it: https://hostyourai.com/api/v1. The key is active immediately.

How do I connect tools like Codex, Claude Code, Cursor, OpenCode or n8n?

Through the same OpenAI-compatible endpoint: enter the Router base URL in your tool together with your API key. In n8n, pick an OpenAI node and replace the base URL there. Example configurations are in the documentation.

How do I connect AI to workflows in Zapier, n8n or Make?

Use the OpenAI integration in those tools and replace the base URL with the HostYourAI Router URL, together with your own API key. For n8n, an example configuration is available in the documentation.

Where can I find documentation and examples?

On the documentation page: the endpoints, examples per tool and the Sovereignty Mode settings.

Models & Router

What is hyai/auto and how does automatic model selection work?

Request the model hyai/auto and the Router picks the best model for your request itself. Handy if you do not want to pin a specific model; you can try it right away in the Playground.

Which models are on the Router?

The current list is in the model catalog and in your dashboard. The offering changes: models are added and sometimes phased out.

How often are new models added and can I request a model?

The Model Garden is updated continuously. Missing a model? Email info@hostyourai.com with which model you need and for what purpose — we will see whether we can make it available on the Router or as a dedicated deployment.

What are the context sizes of the models?

They vary per model and are listed with each model in the model catalog and the documentation.

Why do I get "available on request only" for a model?

That model is not live on the shared Router right now, but it can be made available on request, for example as a dedicated deployment. Email us which model and which use you have in mind.

Do the models really run in the EU?

Yes. All inference runs on GPUs in European data centers. On a default account, traffic can also be routed via Vast.ai and RunPod — US-incorporated GPU marketplaces that operate hardware on EU territory — for capacity and price reasons. If you want to exclude that entirely, enable Sovereignty Mode ("EU only") on your API key; then everything stays with fully European providers. Where every party is established and where it processes is listed on the sub-processors page.

What is the difference between the Router and a dedicated GPU?

The Router is shared capacity: you pay per token, with no fixed cost. A dedicated GPU is your own instance at a fixed hourly rate — interesting for constant load or specific model requirements.

Credits, billing & invoices

What does an average request cost? How do I estimate my monthly usage?

You pay per token; prices per model are on the pricing page and with every model in the catalog. Top up a small amount, measure your real usage in the Playground or via the API, and multiply that by your expected volume.

How do I top up credits?

In the dashboard under Billing. You can pay with the usual payment methods; your credits are available immediately after payment.

Can I set up automatic top-ups?

Yes. With auto top-up under Billing your balance is refilled as soon as it drops below your own threshold, so your credits never run out unexpectedly. You set the amount and the threshold yourself, and you can switch it off again at any time.

Where can I see my usage?

In the dashboard you see your balance, your usage per period and your transaction history. Individual requests are on the Activity page.

Can I see usage per API key?

Partly. The Activity page shows which key made each request, but totals are aggregated per account (or per team). For a clean split per application, use a separate key per application.

Where can I find my invoices?

Invoices are sent by email after each payment and are also available in the dashboard under Billing, including those for automatic top-ups.

How do I change my invoice details (company name, VAT number)?

Update your company details in your account settings; new invoices will then use those details. For corrections on an invoice that was already sent, email info@hostyourai.com.

Do my credits expire?

No. Topped-up credits remain valid as long as your account exists.

Can several colleagues work under one company account?

Yes, with a team. You invite colleagues by email address and then share router keys and dedicated instances with the whole team. Usage is always billed to the account of the key owner; balance and invoices stay with that owner.

Privacy, data & compliance

Where do your servers run? Do my data stay in Europe?

All inference runs on GPUs in European data centers. On a default account, traffic can be routed via Vast.ai and RunPod (US-incorporated GPU marketplaces, hardware on EU territory) alongside European providers, for capacity and price reasons. If you want to exclude that, enable Sovereignty Mode on your API key: then everything stays entirely with European providers. The full list is on the sub-processors page.

What happens to my data? Is it used for training?

No. Prompts and outputs are not used to train models, and we do not log the content by default. Metadata such as model name, token counts and latency is kept for billing and abuse detection; which data is kept for how long is listed in the security overview.

What is Sovereignty Mode and how do I enable it?

Sovereignty Mode restricts your traffic to fully European infrastructure and European model providers. You enable it per API key with the "EU only" switch, also after the key exists. From then on the Router only routes via sovereign routes.

Do you have a DPA (data processing agreement)?

Yes, the standard DPA is available at hostyourai.com/legal/dpa. For a signed copy in your company name, email info@hostyourai.com with: legal company name, registered address, VAT ID or registration number, authorized signatory, DPO or privacy contact, and the email address of your account. We return it countersigned within two working days. For custom clauses we will get in touch.

Account & interface

Can I test the Router in the browser before connecting anything?

Yes. The Playground in your dashboard lets you test any model directly in the browser, using your own credits, without connecting anything.

Which languages are the interface and invoices available in?

The dashboard is available in English and Dutch; you switch with the language picker in the top bar. The website is also available in German. Invoices and communication in English are available on request: let us know via info@hostyourai.com.

How do I delete my account and data?

Email info@hostyourai.com from your account address. We delete your account and personal data; legally required retention periods, for example for invoices, still apply. If you still hold a balance, we refund the remainder to the payments it came from; manually granted credit expires.

Dedicated GPUs

How do I stop a dedicated deployment and when does the cost meter stop?

A dedicated instance has no paused state: it exists or it does not. You delete it in the dashboard or with DELETE /api/v1/instances/{id}, and billing stops at that moment. Note: a running deployment keeps costing money, even without traffic. Every deployment stays visible in your History, with the minutes it ran and the amount actually charged.

What happens when my balance runs out?

If auto top-up is on, we first try to refill your balance. If that fails, your running dedicated instances are removed so the costs do not keep running, and the Router serves your requests again as soon as there is balance.
