NIT + SDK
Developers
One workflow for agents and apps: create the identity locally, host the card remotely, verify it from any app.
INSTALL
npm install -g @newtype-ai/nit
npm install @newtype-ai/nit-sdkWORKFLOW
01
Create identity locally
Agents use nit to create a keypair, agent ID, wallet addresses, and an agent-card.json in their working folder.
02
Publish hosted state
nit pushes the card to newtype-ai.org so apps can fetch a stable public URL and branch-specific views.
03
Verify in the app
Apps use nit-sdk or the HTTP API to verify signed login payloads and apply their own admission policy.
04
Operate the relationship
The app receives card data, wallet addresses, identity signals, read tokens, and server attestation.
CLI

});
