Project Brief AI-Native eCommerce Platform for Physical Products Overview We are building a production-grade, AI-ready eCommerce platform for physical products that supports end-to-end AI-to-AI commerce. Customers must be able to purchase products by submitting natural language requests through ChatGPT, Grok, or other agentic front-end applications. These agents will securely communicate with our backend services to complete the full transaction lifecycle automatically. This is not a traditional Shopify or WooCommerce site. This is an API-first, agent-native commerce system designed for automation, subscriptions, shipping, and support. We are seeking a senior developer or a small team to deliver this system as a fixed-price project with clearly defined milestones. Architecture Expectations (Non-Negotiable) Headless custom commerce backend (API-first) AI and LLM discovery endpoint (for example: /.well-known/ai-agent) Secure agent gateway with OAuth or JWT, schema validation, and idempotency Stripe payments with Affirm (BNPL) enabled Shippo or EasyPost for shipping and tracking Backend-owned subscription and recurring reorder logic Dockerized deployment Azure cloud preferred Milestones and Fixed Payments Milestone 1: Architecture, Discovery, and Gateway Foundation Deliverables System architecture documentation API gateway with OAuth or JWT authentication, request schema validation, idempotency support, and audit logging AI discovery manifest at /.well-known/ai-agent with tool definitions for product search, cart, checkout, and order status Deployed development environment using Docker and Azure Acceptance Criteria LLM clients can discover backend tools programmatically Invalid or unsafe requests are rejected Gateway is deployed and reachable Payment: Fixed for Milestone 1 Milestone 2: Product Catalog, Search, and Cart Automation Deliverables Product catalog service with CRUD, variants, and pricing Natural-language-friendly product search endpoint Cart creation and management APIs Inventory availability checks Admin interface or bulk import mechanism Acceptance Criteria AI agent can search products AI agent can add items to a cart AI agent can retrieve cart totals programmatically Payment: Fixed for Milestone 2 Milestone 3: Payments and Checkout Automation Deliverables Stripe integration using Checkout Sessions or Payment Intents Apple Pay and Google Pay support Affirm (BNPL) via Stripe Secure handling of payment tokens with no raw card storage Webhooks for payment success and failure Order creation on successful payment Acceptance Criteria AI agent can complete a purchase end to end Affirm appears as a payment option when eligible Orders are idempotent with no double charges Payment: Fixed for Milestone 3 Milestone 4: Shipping, Tracking, and Order Status Deliverables Shippo or EasyPost integration Shipping rate calculation Shipping label creation Tracking number storage Order status and shipment tracking endpoints Acceptance Criteria AI agent can answer where is my order AI agent can provide tracking numbers Carrier status updates are accurate Payment: Fixed for Milestone 4 Milestone 5: Subscriptions, Reorders, and Automation Deliverables Backend-managed recurring purchase logic User consent tracking Configurable schedules such as 30, 60, or 90 days Auto-reorder or ask-before-reorder modes Stripe saved payment method reuse Acceptance Criteria AI agent can offer subscription or reorder options AI agent can schedule recurring purchases AI agent can execute reorders automatically when due Payment: Fixed for Milestone 5 Milestone 6: Support, Notifications, and Admin Controls Deliverables Support agent tools to open tickets, schedule support calls, and fetch order or shipping status Email and SMS notifications for order confirmations, shipment updates, and payment alerts to staff Basic admin dashboard for orders and support Acceptance Criteria Support workflows are fully operable via API Internal alerts are sent reliably Admin can monitor system activity Payment: Fixed for Milestone 6 Milestone 7: Hardening, Documentation, and Handoff Deliverables Security hardening including rate limits, logging, and redaction Full API documentation using OpenAPI Deployment documentation for Docker and Azure Test scripts or Postman collection Final demo walkthrough Acceptance Criteria System can be deployed from scratch using documentation All milestone features are verified Clean and complete handoff Payment: Fixed for Milestone 7 Required Skills Backend engineering using Node.js with TypeScript or Python with FastAPI API-first design and OpenAPI documentation Stripe payments and webhook handling Shippo or EasyPost integrations OAuth and JWT security Docker and cloud deployment Experience with AI or LLM integrations is a strong plus Application Requirements Relevant projects involving API-first systems, eCommerce, automation, or AI integrations Proposed timeline per milestone Fixed-price estimate per milestone Architecture approach in one to two paragraphs Any assumptions or risks you foresee Important Notes This is a serious production project, not an experiment Clean architecture, security, and maintainability are prioritized over speed Clear communication and strict milestone discipline are mandatory

Hi, This is Elias from Miami. I reviewed your brief and I completely get what you’re building — this is an API-first, agent-native commerce backend where ChatGPT/Grok can securely discover tools, build carts, run checkout, and manage subscriptions automatically. Not Shopify, more like “Stripe + shipping + subscriptions as programmable infrastructure for AI agents.” I’ve built similar headless + automation-first systems with secure gateways, Stripe webhooks, and shipping integrations, so this is a strong fit. I like that your milestones are already structured properly (gateway → catalog → checkout → shipping → subscriptions → support → hardening). I can deliver clean Docker + Azure deployment with strict idempotency, audit logs, and OpenAPI docs throughout. Additionally, a few project-specific questions: -Q1 Will the /.well-known/ai-agent manifest follow an OpenAI-style tool schema, or do you want it platform-agnostic for multiple agents? -Q2 For subscriptions, should recurring reorders run fully backend-driven on schedule, or always require an agent “confirm” step before charging? -Q3 Do you expect multi-warehouse inventory + split shipments in v1, or single stock location to start? Looking forward to discussing milestone pricing + timeline. Regards.

Hello, I can deliver this as an API-first, agent-native commerce backend on Azure with a secure gateway that enforces OAuth/JWT, strict schema validation, idempotency, and full audit logging so LLM clients can transact safely without double charges or ambiguous state. I’d implement the discovery manifest at `/.well-known/ai-agent` with stable tool definitions for product search, cart, checkout, order status, and support actions, then build the core services (catalog/cart/orders/subscriptions) around deterministic workflows and webhook-driven state transitions. Payments will use Stripe in a PCI-safe model (Checkout Sessions or Payment Intents as appropriate) with Apple/Google Pay and Affirm enabled, and shipping will be integrated via Shippo/EasyPost with rate quotes, labels, tracking, and accurate carrier-status updates. Everything will be Dockerized, fully documented in OpenAPI, and hardened with rate limits, redaction, retries/queueing where needed, plus reproducible deployment notes and test scripts so the system can be stood up from scratch and maintained long-term. Best regards, Juan

Hello donb40, Your project vision is genuinely impressive, building an AI-native, headless eCommerce engine designed for Agentic Commerce shows a forward-thinking approach that bypasses traditional retail friction. To deliver a production-grade, API-first headless commerce backend that enables seamless AI-to-AI transactions and automated fulfillment. Core Strategy: --> Headless & Agent-Ready: Implementation of the /.well-known/ai-agent protocol for instant LLM tool discovery. --> Automated Lifecycle: End-to-end automation from natural language search to Stripe/Affirm payments and Shippo tracking. --> Security & Idempotency: A hardened gateway designed to handle autonomous agent requests without risk of collision or duplication. --> Azure-Native Deployment: Fully Dockerized architecture optimized for Azure’s enterprise-grade cloud environment. A few quick questions: For the AI discovery endpoint, do you have a specific preference for the authentication flow between the 'Consumer Agent' (e.g., ChatGPT) and our backend (e.g., User-Delegated OAuth)? Will the product catalog require real-time synchronization with an existing physical inventory system, or will we build the source of truth from scratch? I will focus on your requirements. I worked on similar projects and can share upon request. Let’s discuss timeline and budget based on these details via chat. Regards, Atta
