# How to Build a Free Name Meaning & Origin Lookup Without API Keys

If you want to build a name meaning and origin lookup tool — similar to নামের অর্থ কি? — but without the hassle of API keys or paid services, here’s a simple guide using public, free APIs.

Why This Matters

People are naturally curious about their names. Whether it's for naming a baby, exploring family roots, or just for fun, knowing the meaning, origin, gender, and popularity of a name adds real value.

If you're building a name-related tool, adding this kind of data makes your app or website more engaging and useful.

Free Public APIs — No API Key Required

These APIs work great together and don’t require any authentication:

API	Purpose	URL Example	API Key?
Genderize	Predict gender	https://api.genderize.io?name=rahim	No
Nationalize	Predict nationality	https://api.nationalize.io?name=rahim	No
Agify	Estimate age	https://api.agify.io?name=rahim	No

---

Example: Fetching Data with JavaScript

Here’s a basic example using vanilla JavaScript:

const name = "rahim";

Promise.all([
  fetch(`https://api.genderize.io?name=${name}`).then(res => res.json()),
  fetch(`https://api.nationalize.io?name=${name}`).then(res => res.json()),
  fetch(`https://api.agify.io?name=${name}`).then(res => res.json()),
])
.then(([genderData, nationalityData, ageData]) => {
  console.log({
    name,
    gender: genderData.gender,
    genderProbability: genderData.probability,
    nationalities: nationalityData.country,
    estimatedAge: ageData.age,
  });
})
.catch(console.error);


**Sample Output**

`{
  "name": "rahim",
  "gender": "male",
  "genderProbability": 0.99,
  "nationalities": [
    { "country_id": "BD", "probability": 0.45 },
    { "country_id": "PK", "probability": 0.30 }
  ],
  "estimatedAge": 34
}`

## Displaying the Info on Your Website

Here's how you might show the data on a webpage using plain HTML and JavaScript:

Loading name information...

const name = "rahim";

Promise.all([
fetch(https://api.genderize.io?name=${name}).then(res => res.json()),
fetch(https://api.nationalize.io?name=${name}).then(res => res.json()),
fetch(https://api.agify.io?name=${name}).then(res => res.json()),
])
.then(([gender, nationality, age]) => {
const countries = nationality.country
.map(c => ${c.country_id} (${(c.probability * 100).toFixed(1)}%))
.join(", ");

document.getElementById("name-info").innerHTML = `
  নাম: ${name} <br/>
  লিঙ্গ: ${gender.gender} (প্রায়ঃ ${(gender.probability * 100).toFixed(1)}%) <br/>
  সম্ভাব্য দেশসমূহ: ${countries} <br/>
  আনুমানিক বয়স: ${age.age}
`;

})
.catch(() => {
document.getElementById("name-info").textContent = "তথ্য লোড করতে সমস্যা হয়েছে।";
});

**Final Notes **

These APIs are free, open, and do not require any API key

They are great for quick projects, learning, or even production use if you cache responses

You can extend this tool by adding name meanings or origin data from other sources like:

- Behind the Name API
- Wikipedia
- Your own local dataset

If you're building something for Bengali-speaking users, this approach works well as a base. You can localize the frontend and combine results with your own dictionary database.
