Multi-Agent System Architecture

Engineered for High-Concurrency Messaging.

Monolithic web apps fail under synchronous messaging spikes. Dromber separates conversational intent parsing, deterministic tool calling, and response synthesis into an asynchronous, event-driven pipeline.

Deterministic Tool Calling

Zero-Hallucination Retail Catalog Interoperability

Direct API bindings to Amazon India PA-API, Flipkart Affiliate API, and Cuelinks networks. Claude 3.5 Sonnet extracts precise product parameters and invokes deterministic inventory lookup functions, verifying real-time stock, pricing, and 24-hr cart attribution before generating links.

Low-Latency Routing

Sub-1.2s WhatsApp Response SLA

Optimized with Anthropic Prompt Caching and edge streaming via Claude 3 Haiku. Token processing latency drops by 70%, keeping consumer interactions fluid within mobile messaging windows.

Stateful Memory

Multi-Turn Context Preservation

Redis-backed session memory maps user intent, prior recommendations, and buyer feedback across multi-turn sessions with automatic token pruning to optimize inference budgets.

Compliance & Attribution

Automated Section 194H TDS & ASCI Disclosures

Every deep link synthesized by Dromber programmatically binds ASCI-compliant advertising tags (#ad, #affiliate) and injects PAN-verified Section 194H (2%/5%) and GST tracking parameters for clean financial auditability.

Frequently Asked Questions

How does Dromber maintain sub-1.2s response times on WhatsApp?

Through a multi-model cognitive pipeline. We deploy Claude 3.5 Sonnet for initial semantic entity extraction and deterministic tool calls, then stream final conversational formatting via Claude 3 Haiku. Coupled with Anthropic's Prompt Caching on catalog schemas, TTFT is reduced by over 70%.

How does the platform prevent hallucinated product prices?

Dromber enforces strict JSON tool calling against real-time commerce APIs (Amazon PA-API, Flipkart, Cuelinks). Recommendations are synthetically bound to live inventory responses; if an item is out of stock or price data fails verification, the engine automatically falls back to secondary catalog matches.

What are the requirements for connecting to WhatsApp Business API?

Dromber connects directly to any Meta WhatsApp Business Cloud API app or BSP (Twilio, Gupshup, WATI). Simply point your webhook URL to our ingestion endpoint and configure your verify token in our dashboard.

How does Dromber handle regulatory compliance and tax attribution?

Every generated deep link passes through our attribution compiler, automatically appending required ASCI disclosure hashtags (#ad, #affiliate) and recording Section 194H TDS (2% or 5%) and GST identifiers in the conversion webhook telemetry.
