Profile
What should persist. Identity, context, permissions, and proof in one private place.
Provenance
What travels. Who owns it, who approved it, and the proof any connected system can check.
Gate
What is allowed. Enforce authority before access, action, or payment.
Your AI shouldn’t start from zero either
Give any agent the identity, context, tools, permissions, and proofs it needs without rebuilding everything for every model or framework. Same profile. New agent. Your AI has access. NEUS gives it authority.Connect in one command
What you can build
Control an agent
Identity, spend caps, revocation. Enforced before action.
Gate and monetize
Gate once. Monetize every qualified visitor.
Ship with the SDK
Hosted check, server confirm, React gate.
Wire MCP tools
One endpoint. Any MCP client.
Check before action
Run once, save the proof, reuse everywhere.
Read the API
Hosted checks, proofs, authority, billing. OpenAPI.
How it works
Verify once. Carry the proof. Enforce before action. Frameworks run tools. Models think. NEUS checks identity, provenance, and authority before sensitive actions.- Verify once. Run a check through the hosted screen, MCP, or SDK.
- Carry the proof. NEUS saves the result with its status, allowed use, and expiration.
- Enforce before action. Connected apps require that proof before access, payment, or execution.
Where NEUS sits
Login gets them in. Authority decides what they do next. NEUS records that authority as a portable proof any connected app can check, so trust travels with the actor, not the app.- Keep your sign-in, identity provider, payment, and agent framework.
- Add NEUS via SDK, API, or MCP. No replacement required.
- No wallet required. Work accounts, domains, social accounts, and passkeys all work. Wallet checks are optional.
