Overview
Send the first six digits of any debit, credit, or prepaid card as the BIN parameter. The API resolves the number against payment card records and returns the card network, card type, issuing bank name, and issuing country. Paid plans add the issuer website, phone number, card category, and ISO country codes with coordinates.
Endpoint
One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.
curl "https://api.apiverve.com/v1/binlookup?bin=448590" \
-H "x-api-key: your_api_key_here"const res = await fetch('https://api.apiverve.com/v1/binlookup?bin=448590', {
headers: { 'x-api-key': 'your_api_key_here' },
});
if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);
const { data } = await res.json();
console.log(data);import requests
res = requests.get(
"https://api.apiverve.com/v1/binlookup?bin=448590",
headers={"x-api-key": "your_api_key_here"},
timeout=15,
)
res.raise_for_status()
print(res.json()["data"])package main
import (
"fmt"
"io"
"net/http"
)
func main() {
req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/binlookup?bin=448590", nil)
req.Header.Set("x-api-key", "your_api_key_here")
res, err := http.DefaultClient.Do(req)
if err != nil {
panic(err)
}
defer res.Body.Close()
out, _ := io.ReadAll(res.Body)
fmt.Println(string(out))
}Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.
Authentication
Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.
A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.
Parameters
Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.
| Parameter | Type | Description |
|---|---|---|
binRequired | string | The first six digits of the credit card number (BIN) length 6–8 |
Response
Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.
{
"status": "ok",
"error": null,
"data": {
"bin": "448590",
"brand": "VISA",
"type": "CREDIT",
"category": "PURCHASING",

"issuer": {
"name": "JPMORGAN CHASE BANK, N.A.",
"country": "United States",

Response fields
Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.
| Field | Type | Example | Description |
|---|---|---|---|
bin | string | "448590" | The BIN number provided in the request |
brand | string | "VISA" | Card brand (VISA, Mastercard, American Express, etc.) |
type | string | "CREDIT" | Card type (CREDIT, DEBIT, PREPAID, etc.) |
categoryPremium | string | "PURCHASING" | Card category (PURCHASING, TRAVEL, etc.) |
country | string | "United States" | Country where card was issued |
issuer | object | {...} | The issuing bank: name, country, phone and website |
name | string | "JPMORGAN CHASE BANK, N.A." | Full name of the issuing bank |
countryPremium | string | "United States" | Country where issuer is located |
phonePremium | string | "1-800-432-3117" | Contact phone number of the issuer |
websitePremium | string | "www.chase.com" | Official website URL of the issuer |
location | object | {...} | Issuing country coordinates and ISO codes |
latitudePremium | string | "37.0902" | Latitude coordinate of issuer location |
longitudePremium | string | "-95.7129" | Longitude coordinate of issuer location |
alpha2Premium | string | "US" | Two-letter ISO country code of location |
alpha3Premium | string | "USA" | Three-letter ISO country code of location |
Errors
Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.
| Status | Meaning | What to do |
|---|---|---|
400 | Input was rejected | Read error; it names the parameter. |
401 | Key missing or invalid | Check the header name and the key value. |
403 | Key valid, but not permitted | A key restriction or IP allow-list; see key scoping. |
429 | Rate limited, or out of credits | Read error to tell them apart; see rate limits. |
Use cases
- Checkout Brand Detection

Other ways to use BIN Lookup
Set up BIN Lookup on APIVerve, or reach the same source a different way. Your APIVerve account and credits work on all of them — one key, one balance.
