Copy-Paste Integration Code

Integrate this validator directly into your application using your production API key:

cURL
curl --request POST \
  --url "https://global-lei-corporate-tax-id-validator-api.stanzaapi.com/api/v1/lei/validate" \
  --header "Content-Type: application/json" \
  --header "x-api-key: YOUR_API_KEY" \
  --data '{
  "lei": "5493006MHB84DD0ZWV18"
}'
Node.js (Fetch)
const response = await fetch("https://global-lei-corporate-tax-id-validator-api.stanzaapi.com/api/v1/lei/validate", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "x-api-key": process.env.API_KEY || "YOUR_API_KEY"
  },
  body: JSON.stringify({
  "lei": "5493006MHB84DD0ZWV18"
})
});

const data = await response.json();
console.log(data);
