Connect Claude & ChatGPT to APIVerve

Ask your AI whether an email address can receive mail, when a domain's SSL certificate expires, or what the VAT rate is in Germany. Through APIVerve it can validate emails and phone numbers, look up domains, DNS, WHOIS and IP addresses, convert currencies and units, check public holidays and working days, and turn web pages or HTML into PDFs.

Questions

What can the AI do in APIVerve?

The AI can validate emails and phone numbers, check domains for availability, phishing, DNS, MX, WHOIS and SSL, look up IP addresses, and get exchange rates, VAT rates, US sales tax, holidays, working days, local time and weather. It can also check grammar, summarize, translate, analyze sentiment, read web pages, and create PDFs, invoices and QR codes.

Does the AI see my APIVerve API key?

No. Your APIVerve API key is encrypted at rest and never shown to the AI. After you save it, it is 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 keep only the lookups you need, for example email validation and exchange rates. Tools that change something can require your approval before they run, and 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 PipMCP 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?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own APIVerve account.

Can I use a sub-key instead of my main API key?

Yes. On the API Key page in the APIVerve dashboard you can create a scoped sub-key and paste that into PipMCP instead of your main key.
