Why Hermes
Platform primitives built for listing teams
Agentic schema engine
Extendable schema logic that adapts to each marketplace taxonomy without brittle rules.
Observability-first
Rich job metadata, structured logs, and webhook callbacks so ops teams stay in control.
Composable SDKs
Ship with TypeScript or REST today; drop-in SDKs for Python, Go, and Java on the roadmap.
How it works

1
Connect
Create an API key and connect your catalog source (HTTP, S3, Kafka).
2
Validate
Run listings through Hermes schema validation and enrich missing fields.
3
Publish
