NEUS turns verification into reusable proof receipts for apps, agents, wallets, APIs, gates, audit, and payments.
It issues a proof receipt after a verification or trusted action, reuse that receipt across surfaces without rebuilding the same trust flow from scratch.

Why teams pick NEUS

Outcome	How NEUS delivers it
Ship faster with less “prove it again”	One flow, a receipt ID, lookup before you re-run verification
Reuse trust across web, API, and agents	Resolvable URLs and handles. Not screenshots that go stale
Safe agent identity and delegation	agent-identity and agent-delegation with scoped permissions
Tools that see live truth	Remote MCP over HTTPS so assistants read current results, not pasted text

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

Layer	What
Core flows	agent-identity, optional agent-delegation
Resolvable handles	https://neus.network/agent/<agentId>, result URLs, wallet, DID
Tooling manifest	Optional JSON from the agent profile. See Agents.
Live checks	NEUS MCP: neus_context, neus_proofs_get (MCP docs)
Linked accounts	Ownership verifiers + wallet-link with the same result model (verifier table)

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

import { VerifyGate } from '@neus/sdk/widgets';

<VerifyGate
  appId="your-app-id"
  requiredVerifiers={['token-holding']}
  verifierData={{
    '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.

Use case	ID
Social ownership	ownership-social
Domain	ownership-dns-txt
Org OAuth	ownership-org-oauth
Pseudonym	ownership-pseudonym
Content / provenance	ownership-basic
Human verification	proof-of-human
Token balance	token-holding
NFT	nft-ownership
Contract	contract-ownership
Wallet risk	wallet-risk
Linked wallets	wallet-link
Content moderation	ai-content-moderation
Agent identity	agent-identity
Agent delegation	agent-delegation

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,
});
