Semarchy API

Master Data Management (MDM) / Enterprise Data Platforms · semarchy.com

Semarchy xDM documents a full REST API for querying, publishing, and certifying golden records, with a published OpenAPI spec. Access is privilege-gated: platform rights plus a per-model Integration API grant, and the spec sits behind a login. HTTP Basic auth is still common in the wild.

SCORECARD

ExistenceGOODA full REST API on the xDM hub covering consume, publish, and certify flows, plus a separate management API.
AccessMIXEDRequires platform privileges plus a per-model Integration API grant; an admin must enable each model.
CoverageMIXEDThe API runs per model and per data location, so multi-domain customers wire several surfaces, not one endpoint.
AuthMIXEDAPI keys and HTTP Basic are both supported; Basic remains common in deployments despite vendor guidance.
Docs & DXPOORThe OpenAPI spec is privilege-gated, reachable only from the platform Welcome page; no official SDK.
StabilityMIXEDPulling straight from the hub can hit rate, payload, and concurrency ceilings that are not documented publicly.
Supergood: Semarchy has an API, with gaps. We cover what it's missing: stable endpoints, normalized JSON, managed auth.

SOURCES
API access requires both platform-level privileges and a per-model 'Grant access to the Integration API' grant, so an end customer with hub credentials cannot necessarily query the REST API without admin enablement semarchy.com
The OpenAPI spec / built-in documentation is itself privilege-gated (must be reachable from the platform Welcome page with sufficient permissions), reducing self-serve discoverability for downstream developers semarchy.com
HTTP Basic auth is supported and still in use in the wild despite Semarchy's own guidance preferring API keys + HTTPS, a known weak link in customer deployments semarchy.com
The REST API operates per-model and per-data-location, so multi-domain customers must wire up and version multiple API surfaces rather than hitting a single unified endpoint semarchy.com
Heavy reliance on bundled xDI (Semarchy's own data integration product) for high-throughput data movement means customers who want to bypass xDI and pull straight from the hub via REST can run into rate, payload, or concurrency ceilings not documented publicly semarchy.com
Some customers report that the platform's value is heavily dependent on implementation and architecture decisions, leading to mixed satisfaction when delivered poorly gartner.com
Historical infrastructure compatibility gaps, e.g. reviewers noted Semarchy was not deployable on Azure at the time of their initial implementation, creating long-term lock-in to original infrastructure choices gartner.com
Pricing is fully custom-quoted with no published rate card, making TCO comparison vs. Reltio/Informatica/Profisee opaque for buyers semarchy.com
Per Info-Tech / PeerSpot comparisons, Semarchy trails Reltio (rank 2) at rank 5 on overall MDM scoring, with smaller mindshare than category leader Informatica peerspot.com
Some reviewers note that competing 'platforms' are stitched-together multi-product suites that don't work out of the box, implying real-world Semarchy deployments still require non-trivial integration work despite the unified-platform marketing g2.com
The Semarchy Data Platform brand consolidated multiple historically-separate products (xDM for MDM, xDI for integration, Stardog-derived data catalog), buyers report confusion about packaging, licensing, and which capabilities are in-scope for which SKU improvado.io
