Why teams pick NEUS

Who this is for

• Product and GTM teams turning wallet, token, NFT, or human checks into gates for drops, bounties, or paid tiers
• Platforms standardizing one trust model across web, API, and automation
• Agent builders shipping identity, delegation, and optional x402 payment unlock (docs)

Quickstart

npm install @neus/sdk

import { NeusClient } from '@neus/sdk';

const client = new NeusClient({ appId: 'your-app-id' });

const proof = await client.verify({
  verifier: 'ownership-basic',
  content: 'Verified bounty submission',
  wallet: window.ethereum,
});

const { proofId } = proof;
const signerAddress = '0x...';

const check = await client.gateCheck({
  address: signerAddress,
  verifierIds: ['ownership-basic'],
});

console.log(check.data?.eligible);

Linked profiles, agents, and automation

Fast path: Hosted Verify | billing and caps in app setup | paid flows: x402

Setup (any chat or IDE)

1. Get started
2. Register agents via SDK, Hosted Verify, or MCP neus_agent_create, then neus_agent_link. Agents | Cookbook.
3. Share a resolvable handle (agent URL, result URL, wallet, DID) and use NEUS MCP for live state.
4. Optional: export config JSON for hosts that load tool manifests from a URL.

React gate

    'token-holding': {
      contractAddress: '0x...',
      minBalance: '100.0',
      chainId: 1,
    },

Hosted Verify

Hosted Verify is the browser flow at https://neus.network/verify: a parameterized checkout on NEUS. Your app keeps the proof ID and checks before you prompt again.

Examples:

https://neus.network/verify?verifiers=proof-of-human&returnUrl=https://myapp.com/callback

Agent onboarding: https://neus.network/verify?preset=agent-pack

Verifiers

Live catalog: Verifier catalog. Machine-readable lists and schemas ship in spec/ for reference and validation tooling.

Agents (SDK)

await client.verify({
  verifier: 'agent-identity',
  data: {
    agentId: 'my-bot',
    agentWallet: '0x...',
    agentChainRef: 'eip155:8453',
    agentType: 'ai',
  },
  walletAddress: agentWallet,
});

await client.verify({
  verifier: 'agent-delegation',
  data: {
    controllerWallet: '0x...',
    controllerChainRef: 'eip155:8453',
    agentWallet: '0x...',
    agentChainRef: 'eip155:8453',
    scope: 'payments:x402',
    permissions: ['execute', 'read'],
    maxSpend: '25000000',
    expiresAt: Date.now() + 7 * 24 * 60 * 60 * 1000,
  },
  walletAddress: controllerWallet,
});
