Hermes API for marketplace listings

Hermes transforms raw product data-images, text, attributes—into validated, cross-marketplace listings using an agentic schema engine. Structured. Deterministic. Observable. Built for high-volume automation. All powered by fast, memory-efficient Rust services and LLM-driven pipelines designed for real throughput.

Everything you need to ship listings at scale

Hermes abstracts the unglamorous but critical infrastructure: auth, rate limits, queueing, retries, observability, and billing. You bring product data. Hermes handles concurrency, schema generation, and distribution to marketplaces. Under the hood: async Rust, vector retrieval, structured LLM calls, and aggressive caching tuned for low-latency commerce automation.

Universal Listing Schema

Hermes normalizes unstructured product data into a universal schema (HSUF) synced with marketplace metadata APIs. A single format that maps cleanly to eBay, Amazon, Etsy, Shopify, and internal systems. Translate once. Ship everywhere.

Agentic Pipelines

Composable Rust services orchestrate LLM modules for classification, attribute extraction, category inference, pricing, and full listing generation. Every step is observable, retryable, and fully typed.

Explainable Execution Graph

Hermes logs every transformation—LLM calls, embeddings, retrieval steps, and pipeline outputs—into a transparent execution graph. No black boxes. Fully reproducible, operator-friendly workflows.

Rust-Native Infrastructure

Hermes runs on async Rust with Tokio, serde-driven validation, vector retrieval via Qdrant, multi-queue workers, and fine-grained rate controllers. Designed like a trading system: fast, predictable, reliable.

API-First Commerce Automation

Integrate Hermes directly into your stack. Call individual modules or orchestrate full listing flows. Hermes handles concurrency, retries, distribution, and schema validation under the hood.

Marketplace Intelligence

Hermes syncs continuously with marketplace category trees, metadata rules, and listing constraints—automatically keeping workflows compliant without manual rule maintenance.
