# Distributed Inventory Feed

*/Software/Distributed_Inventory_Feed*

## Solution Overview

Distributed Inventory Feed is a headless SaaS engine that normalizes real-time stock levels across fragmented supply networks into a single available-to-promise metric. The platform queries independent 3PL warehouses, retail backrooms, and dropship suppliers, reconciling conflicting data formats into a unified JSON API endpoint. The direct output is an accurate SKU availability count that dynamically accounts for safety stock, in-transit units, and pending returns.

Headless commerce architects and e-commerce merchandising teams integrate this feed to prevent overselling events and split-shipment routing errors. By decoupling the true inventory state from monolithic ERPs, the feed eliminates the synchronization latency that typically causes storefronts to display items as in-stock long after the physical warehouse bins are empty.

Operating as a data primitive at the base of the commerce stack, the feed consumes raw EDI 846 documents and legacy SOAP webhooks from warehousing systems like Manhattan Associates or NetSuite. Above it, intelligent order routing agents, storefronts, and automated marketplace repricers consume the normalized feed to adjust front-end visibility and execute fulfillment logic without repeatedly querying the underlying databases.

## Headless Saas Data Model

**Entities**:
- Name: StockPosition · Description: Normalized available-to-promise inventory metric for a specific SKU
- Name: Merchant · Description: The tenant organization operating the storefront and supply network
- Name: FulfillmentNode · Description: Physical warehouse, backroom, or dropship supplier holding physical stock
- Name: FeedConnection · Description: Ingestion configuration for parsing raw EDI or SOAP webhook data
- Name: NodeInventory · Description: Raw un-normalized stock counts for a SKU at a specific node
**Relations**:
- To: StockPosition · From: Merchant · Label: aggregates stock into · Cardinality: one-to-many
- To: FulfillmentNode · From: Merchant · Label: operates · Cardinality: one-to-many
- To: FeedConnection · From: FulfillmentNode · Label: ingests from · Cardinality: one-to-many
- To: NodeInventory · From: FulfillmentNode · Label: holds · Cardinality: one-to-many
- To: NodeInventory · From: StockPosition · Label: is reconciled from · Cardinality: one-to-many
**Tenant Anchor**: Merchant
**Primary Resource**: StockPosition

## Api Definition

**Protocols**:
- REST
- GraphQL
- MCP
- SDK
- Webhooks
**Consumed By**:
- [Order Routing Agent](/Agents/Order_Routing_Agent)
- [Marketplace Repricer Agent](/Agents/Marketplace_Repricer_Agent)
- [Inventory Allocation Agent](/Agents/Inventory_Allocation_Agent)
**Integrations**:
- [Manhattan Associates](/Products/Manhattan_Associates)
- [NetSuite](/Products/NetSuite)
- [SPS Commerce](/Products/SPS_Commerce)
- [TrueCommerce](/Products/TrueCommerce)
**Consumption Model**: An agent initializes the MCP server to evaluate real-time available-to-promise metrics before routing orders, subscribing to webhooks for out-of-stock events.
**Workflow Wrappers**:
- Name: Calculate Global ATP · Wraps: Pulls raw node inventories, deducts safety stock and pending returns, and updates StockPosition.
- Name: Ingest EDI Feed · Wraps: Parses raw EDI 846 payloads, maps to NodeInventory counts, and triggers position recalculation.
- Name: Sync Fulfillment Node · Wraps: Pings the feed connection endpoint, polls latest SOAP updates, and reconciles node records.

## Api Function Cascade

**Ai Role**: Operating as a fully digital headless primitive, the system utilizes generative AI exclusively for fuzzy SKU normalization to align disparate vendor feeds, while deterministic code handles all ingestion, available-to-promise calculations, and webhook broadcasting entirely without human intervention.
**Cascade**:
- Kind: Code · Note: Pulls raw stock counts from TrueCommerce, SPS Commerce, and NetSuite endpoints. · Step: Fetch Node Inventories · Verb: fetch · Realizes: Gather Inventory Data · Oversight: none
- Kind: Code · Note: Translates EDI 846 and SOAP responses into a normalized JSON schema. · Step: Parse EDI Payloads · Verb: parse · Realizes: Process Electronic Data Interchange · Oversight: none
- Kind: Generative · Note: Normalizes vendor-specific variants into the canonical master SKU format. · Step: Resolve Unmatched SKUs · Verb: map · Realizes: Standardize Product Identifiers · Oversight: review-on-exception
- Kind: Code · Note: Deducts dynamic safety stock and pending returns from aggregate counts. · Step: Calculate Global ATP · Verb: calculate · Realizes: Calculate Available To Promise · Oversight: none
- Kind: Code · Note: Broadcasts real-time ATP metrics to downstream Order Routing Agents. · Step: Emit Stock Position Webhooks · Verb: emit · Realizes: Distribute Event Notifications · Oversight: none
