Use a model a lot? Ask for a better rate.
Pick the model in the dashboard, say roughly how much you expect to use, and request a discount. Once approved it applies to every call to that model, and each response shows what you saved against the vendor\u2019s list price.
- 01
Request
Open the model in the dashboard and ask for a discount with your expected volume.
- 02
Approval
We review it, usually within a business day, and set the rate for your organization.
- 03
Savings
The discount applies automatically. Every response reports the saving versus direct.
Expecting serious volume before you sign up? Tell us the models and numbers and we come back with a rate.

Straight answers.
How is OSMEXO cheaper than calling the vendor directly?
Every model is priced at the vendor’s published list price or below, and there is no platform fee on top. Because we route across several providers for the same model, we can grant volume discounts per model. Each response tells you what the same tokens would have cost direct.
What does “discount on demand” mean?
From the dashboard you pick a model you use a lot and ask for a better rate. We review the request, usually within a business day, and the approved discount applies to every call to that model from then on. Nothing to renegotiate with each vendor.
What is a verified route?
A provider only serves a model after our automated checks confirm it returns the right model, a correct answer and acceptable latency. Providers that fail or drift are removed from rotation automatically. You never call an unverified path.
Do I have to change my code?
Only the base URL and the key. The gateway speaks the OpenAI wire format for chat, responses, embeddings, images, speech and transcription, so the official OpenAI SDKs and most frameworks work as they are.
How do I pay?
Prepaid credits, from $1. Pay with USDC on Base from any wallet, or in US dollars through PayPal, Venmo, Cash App or Wise. Card payments are coming. There is no subscription and no seat fee.
What happens when a provider goes down?
The gateway retries and falls back to the next verified provider for that model before the first token is sent, so your users see a slower answer instead of an error. You can see which route answered on every request.
Can I control spending?
Yes. Set a monthly limit for the organization, a daily or monthly budget per API key, and a low-balance alert. Purchases are capped per day and per month and can be raised on request. Unusual spend triggers an alert.
Is my data used for training?
No. Prompts and completions pass through to the provider you are routed to and are stored only as much as you choose for your own request logs. Keys are stored hashed and secrets are never logged.
Same models. Same code. Smaller bill.
Create a key, change the base URL, and see on the very first response what you saved.
