}Agentic-commerce MCP: search across merchants, fetch structured offer manifests, and dry-run checkout + negotiation before buying.
Commerce infrastructure built for buyer agents and the businesses they transact with.
Nexez turns a business's offers into public, structured listings that humans can browse and AI agents can search, understand, compare, validate, negotiate, and take to checkout. Sellers maintain one source of truth while Nexez publishes the web experience, machine-readable artifacts, transaction workflows, and operational controls around it.
Nexez is more than an AI landing-page builder: this repository contains the seller platform, buyer-agent interfaces, commerce protocols, payment and negotiation lifecycle, integrations, analytics, and release-safety systems.
- Structured listings for services and products, including fixed-price and negotiable offers.
- Human-readable public pages with semantic HTML and JSON-LD.
- Per-listingagent.json,llms.txt, MCP manifest and JSON-RPC endpoint, and scoped OpenAPI.
- Platform-wide agent index, search API, MCP endpoint, OpenAPI document, andllms.txt.
- Seller storefronts that group multiple listings and expose storefront-level agent artifacts.
- Verified custom domains, branding, themes, reusable templates, drafts, and controlled publishing.
- Agent-readiness scoring, crawlability checks, deterministic and LLM-assisted simulation, AI optimization, and authenticated competitor analysis.
- Intent search with location, industry, readiness, capability, and price signals.
- Public machine discovery through/.well-known/agent.json,/.well-known/mcp.json,/agent-pages.json,/agent.json,/openapi.json, and/llms.txt.
- MCP tools for search, directory browsing, page inspection, dry-run checkout validation, and dry-run negotiation validation.
- REST APIs, owner API keys, signed outbound webhooks, and copy-paste buyer-agent examples.
- Published TypeScript SDK:npm install @nexez/agent-sdk.
- Published Python SDK:python -m pip install nexez-agent-sdk.
- Published OpenClaw discovery skill:openclaw skills install nexez-agent-discovery.
- Published OpenClaw tool plugin:openclaw plugins install npm:@nexez/openclaw-nexez.
- WordPress and Shopify integrations inplugins, including Shopify catalog sync and proxied machine artifacts.
- Fixed-price checkout through Stripe Connect, with the seller as merchant of record and Nexez application fees captured from the connected account.
- Negotiable offers with budget, timeline, scope, seller rules, asynchronous decisions, agreement state, status tokens, and payment handoff.
- Dry-run validation before consequential checkout or negotiation actions.
- Short-lived action-approval tokens, explicit buyer approval, and stable idempotency keys.
- Persistent orders, buyer receipts and order portals, refunds, disputes, reviews, and transaction-livemode provenance.
- Reconciliation workers and deduplicated webhook processing for payment and billing state.
- ACP and UCP product feeds for agent discovery.
OpenAI ACP and Google UCP checkout-session routes are implemented but fail closed until the corresponding partner enrollment and shared credentials are enabled. Their product feeds remain available for discovery. Seedocs/agentic-commerce-enrollment.mdfor the deployment boundary.
- Multi-listing and multi-storefront management with plan-aware publishing limits.
- Stripe, Shopify, Square, Calendly, Acuity, and Google Calendar integration surfaces.
- Provider-aware catalog synchronization that preserves manually authored offers.
- Live availability, booking webhooks, outbound automation webhooks, and integration health.
- Agent-versus-human traffic analytics, funnel and conversion reporting, offer performance, finance reporting, negotiation metrics, filtering, and exports.
- Team invitations and collaboration, billing portal, subscription reconciliation, support, referrals, saved pages, and notification workflows.
- Nexie buyer-agent threads with streaming responses and structured approval cards.
- Saved sellers and searches, scheduled agent tasks, notifications, referrals, and order tracking.
- Buyer data export and deletion controls that preserve a seller account when the same identity also operates a business on Nexez.
Nexez treats public discovery and consequential actions as different trust boundaries:
- Discovery artifacts expose published seller information without exposing drafts or secrets.
- Checkout and negotiation support side-effect-free validation before action.
- Mutating agent flows require matching approval context and are protected against retries.
- Database row-level security and explicit grants protect authenticated and service-only data.
- Provider credentials live in private server-side storage and are excluded from public artifacts.
- Rate limits, signed webhooks, replay protection, scoped status tokens, money constraints, and append-only evidence ledgers provide defense in depth.
- Test and live transaction provenance remains explicit.
The internal security and privacy baseline is documented indocs/trust/README.md. It is a control framework, not a claim that Nexez has completed a SOC 2, PCI DSS, or other independent assessment.

- Application:Next.js 16 App Router, React 19, TypeScript, Tailwind CSS, and Radix/shadcn UI
- Data and identity:Supabase Auth, PostgreSQL, Row Level Security, and Storage
- Commerce:Stripe Connect and Stripe Billing
- AI:deterministic fallbacks plus configurable OpenAI-compatible and native adapter layers for OpenAI, Gemini, Claude, and Grok
- Deployment:Vercel, scheduled workers, and GitHub Actions
- Quality:Vitest, Testing Library, Playwright, ESLint, TypeScript, protocol gauntlets, and live non-money-moving smoke checks
The full platform requires private Supabase and service configuration. Optional integrations remain dormant or fail closed when their credentials are absent.
