Openai App Store Integration

Overview

Nexlabs is integrating Vibe Coding as a ChatGPT “app,” letting users trade Nexlabs indexes through plain-language instructions—e.g., “Buy me CRYPTO5 index with Nexlabs.” This builds on our BYOI and AI-Agent roadmap: natural-language intents are translated into verifiable, policy-safe actions with explicit user confirmation.

Why this matters

• Frictionless UX: No command syntax or dashboards required; users act from chat.

• Trust & control: Human-in-the-loop confirmations, strict scopes, and transparent fees/slippage.

• Composability: The same trading capability can be invoked from any MCP-compatible client.

Architecture:

1. Vibe MCP Server: exposes trading tools over HTTPS.

2. Client (e.g., ChatGPT app): plans actions, renders our confirmation UI, calls tools.

3. Auth: OAuth 2.1 (scoped tokens like trade.read/trade.write).

4. Nexlabs Core: quotes, KYC/limits, execution, receipts.

Exemplary user flow:

1. User: “Buy me CRYPTO5 index with Nexlabs for $250.”

2. App calls quote_index_order → shows price, fees, slippage.

3. User confirms → app calls place_index_order.

4. Receipt returned (orderId, avgPrice, txHash).

Tooling we expose

• quote_index_order – Return live quote, est. slippage/fees for an index order.

  • Inputs: indexSymbol, side, notional, currency

  • Output: price, est. total, slippage, quoteId, expiry

• place_index_order – Place a confirmed buy/sell. (Write scope required.)

  • Inputs: indexSymbol, side, notional, currency, quoteId?, clientRef?, maxSlippageBps?

  • Output: orderId, status, filledNotional, averagePrice, txHash

• get_positions – Read current holdings and P&L. (Read scope.)

  • Output: positions array (symbol, qty/notional, basis, Unrealized P&L)

Use Vibe Coding outside our website

Vibe Coding is not limited to the Nexlabs UI. Because it’s exposed via the MCP server:

• It can be used inside ChatGPT (as the “Nexlabs – Trade & Indexes” app).

• It can be embedded in other MCP-aware clients (IDEs, copilots, internal assistants).

• Partners can integrate via our documented HTTPS endpoint with OAuth-scoped access.

Security & Compliance

• Auth: OAuth 2.1 with short-lived tokens; per-tool scopes.

• Confirmations: Mandatory human confirmation for any state-changing action.

• Guardrails: Regional checks, KYC/AML gating, max-slippage enforcement, clear error returns.

• Privacy: Minimum data sharing; no secrets in prompts; audit logs server-side.

Rollout

• Phase 1: App launch on Nex Labs dApp

• Phase 2: Openai App store listing (onboarding to be announced by Openai, still in beta)

• Phase 3: Toolset expansion (redeem, rebalance, withdrawals) and analytics components.

Automated payment with x402 protocol

The open-source x402 protocol, managed by Coinbase, allows agents to ask for payment (with subcent gas fee costs) before returning the response. Our agent, connected by a crypto address, can ask for payment to perform wallet management directly on a users wallet without requiring a (non-custodial) vault to move the assets into. Furthermore, we have valuable datafeeds related to indices and their constituents that can be shared. Variable such as:

• market cap

• on-chain data:

  • TVL (per chain, per pair)

  • Active User addresses

• volatility
