Build secure, scalable identity verification systems using PALAP's gRPC-based microservices for decentralized identity attestation and verification.
// Using Node.js
npm install @grpc/grpc-js @palap/identity-proto
// Python
pip install grpcio palap-identity
const client = new IdentityClient(
'grpc.palap.org:443',
credentials.createSsl(rootCert),
{
'grpc.default_authority': 'palap.identity'
}
);
const metadata = new Metadata();
metadata.add('x-api-key', 'YOUR_API_KEY');
client.authToken(metadata, (err, response) => {
console.log(response.status);
});
