Ask your AI whether an email address is real, whether a UK number may be called for marketing, or what a company's filed financials show. It uses Data8 to validate emails, phone and mobile numbers, IBANs and UK bank accounts, find and format addresses, clean and split names, and look up businesses and UK companies. Most checks use your Data8 credits.

Questions

What can the AI do in Data8?

It can validate email addresses, phone numbers, mobile numbers, UK phone lines, websites, IBANs and UK bank accounts, format phone numbers and check UK numbers against TPS and Corporate TPS. It can search and retrieve addresses, detect a contact's country and clean or parse names. It can also search businesses and UK companies and get Companies House details, filed financials and business credit checks.

Does the AI see my Data8 API key?

No. Your Data8 credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can turn on only the checks you need. Tools that use Data8 credits, such as credit checks and email validation, can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Data8 account, and most checks use your Data8 credits.

Do the checks use my Data8 credits?

Most of them do. Validations, address lookups, name cleaning, business credit checks and financials are charged to your Data8 credits, the same as when you call Data8 directly. You can switch off the tools you do not want the AI to use, or require approval for them.
