Using the API or the MCP server

Both require sign-in. The quickest fixes, in the order they come up:

• 401 from the REST API means no key, or one we cannot resolve. Create one at /dashboard/api-keys and send it as a bearer token. The API reference has copy-pasteable examples.
• 401 from the MCP server is expected on a first call: the response advertises our authorisation server, so an OAuth-capable client such as Claude or ChatGPT will send you here to sign in and approve the connection. There is no key to copy. See connecting the MCP server.
• A result that looks wrong or stale is worth reporting with the product URL. Every fact we publish carries its source and the date we checked it, so tell us what you expected and we can re-check the source rather than guess.
• Writing an agent against us? /for-ai covers the endpoints, the canonical URIs to cite, and the ranking profiles.

Still stuck: email us with the request URL or tool name, the time, and what came back.

You are the vendor of a listed product

You can claim your listing and submit evidence yourself, for free, at account.vioscale.ai. See /for-vendors for what claiming lets you do.

If a published fact about your product is wrong, dispute it with a source and we will re-check it against that source. We do not change a score on request and we take no payment to alter a ranking; the reasoning is in how we stay independent and the scoring itself is documented in our method.

Email support@vioscale.ai for anything the portal cannot do, including a takedown request.

Account and billing

Reset a password from the sign-in page. For anything else on your account, including closing it, email support@vioscale.ai from the address the account uses, so we can tell it is you.

Privacy and your data

To access, correct, export or delete your personal data, use the data request form, which routes straight to us and is the fastest path. The privacy policy sets out what we process and why.

Security

Report a suspected vulnerability to support@vioscale.ai with enough detail to reproduce it. Please give us a reasonable chance to fix it before disclosing it publicly. We will confirm receipt and tell you what we find.
