Choose an integration path
Three drop-in paths cover most products. Pick the one that matches what you are building.Gate an app or marketplace
Publish a portal, embed VerifyGate, reuse receipts at checkout.
Connect an assistant
One command:
neus setup — same account and receipts in Cursor, Claude Code, Codex, and VS Code.Check agents before action
Agent identity and permission receipts a runtime can check before tools run.
What NEUS handles
Free Basic includes monthly credits for hosted sign-in, portals, and API checks. Pro adds 10,000 monthly credits, Zeus, hosted AI (or your own model key), higher API throughput, and priority support. Plans.
Products and use cases
AI agent and assistant permissions
Register an agent, set limits, check them before action in a connected runtime.
Identity and account checks
Passkey, OAuth, social, org, and domain results as reusable receipts.
Access gates and eligibility
Require current receipts before content, memberships, rewards, or API access.
Human and abuse checks
Layer human and account checks so one weak signal is not enough.
Credits and checkout
You pay for checks by default — or charge visitors at the gate.
Reuse across apps
Check → verify → save → reuse — one loop for widgets, API, and MCP.
Core receipt flow
Most integrations follow the same loop: check → verify → save receipt → reuse. See Integration.Build with

Widgets
