Connect Claude & ChatGPT to GenderAPI.io
Ask your AI to guess the likely gender for a first name, an email address or a username with GenderAPI.io, or to run a whole list at once. It can add a country code for better local results, validate phone numbers and show how many credits you have left.
Free plan, no credit card. Takes about a minute.
Try asking
“What is the likely gender for the name Andrea in Italy?”
The AI sends the name with the country code IT and returns GenderAPI.io's guess.
“Guess the gender for these 30 sign-up emails.”
It sends them in one batch of up to 50 items, each marked as an email, and returns a result per address. Each item uses one credit.
“What does the username sam_k91 suggest?”
It runs a guess with the type set to username.
What your AI can do
Single guesses
Guess the likely gender from one first name, email address or username, with an optional country code.
Batch guesses
Send up to 50 names, emails or usernames in one call, using one credit per item.
Phones and usage
Validate phone numbers with an optional country code, and check your credit balance and usage.
“Is +45 12 34 56 78 a valid phone number?”
It checks the number and returns whether it is valid, with its details.
“Validate 20 12 34 56 as a Danish number.”
It passes the country code DK so the local number can be checked.
“How many credits do I have left?”
It reads your account's credit balance and usage.

Questions
What can the AI do in GenderAPI.io?
It can guess the likely gender for a first name, email address or username, one at a time or up to 50 in a batch. It can also validate phone numbers and show your credit balance and usage.
Does the AI see my GenderAPI.io API key?
No. Your GenderAPI.io 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 you switch on.
Can I control what the AI is allowed to do?
Yes. You choose which tools are switched on. Guesses use your API credits, and a batch uses one credit per item, so batch guesses and phone 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, turn on Developer mode and add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link works in Claude under Settings › Connectors › Add custom connector, and in Cursor.
What does it cost?
PipMCP has a free plan, and you do not need a credit card to start. Paid plans are billed per completed task. You also need your own GenderAPI.io account. Lookups use the credits on your GenderAPI.io account.
How do I keep track of credits?
Ask the AI for your usage. It reads your credit balance and usage from GenderAPI.io. v1 and v2 of the API share the same key and credit balance, so the number covers both.
