Cartegraph API
A REST API exists for the Cartegraph (OpenGov EAM) platform covering assets, libraries, attachments, and import/export. Documentation sits behind a customer login on campus.cartegraph.com and API access may carry extra licensing cost. Capabilities shift between Classic OMS and new EAM releases.
Frequently asked questions
Cartegraph scores F on the API Report Card. A REST API exists for the Cartegraph (OpenGov EAM) platform covering assets, libraries, attachments, and import/export. Documentation sits behind a customer login on campus.cartegraph.com and API access may carry extra licensing cost. Capabilities shift between Classic OMS and new EAM releases.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.
Cartegraph (now branded OpenGov Enterprise Asset Management, formerly Cartegraph OMS / Cartegraph Asset Management) is a cloud-based enterprise asset management (EAM), computerized maintenance management (CMMS), and work order platform for state and local government.
Government / Public Sector, specifically cities, counties, special districts, and state agencies managing infrastructure such as roads/transportation, water and wastewater utilities, stormwater, parks & recreation, public facilities, and fleet. Public works supervisors, water/sewer crews, parks staff, facilities managers, and fleet techs use Cartegraph to inventory geospatially located assets (signs, signals, pipes, hydrants, pavement segments, vehicles, buildings, trees), create and close work orders against those assets, schedule preventive maintenance, log inspections (often FEMA-reportable), capture costs (labor, equipment, materials), and roll up to capital improvement plans.
High within the public-sector EAM niche.
Cartegraph is the system of record for public infrastructure operations: every asset (with GIS coordinates, condition score, install date, replacement cost), every work order (labor hours, equipment usage, materials, costs), every preventive maintenance schedule, every inspection record (including FEMA-reportable events), every citizen service request, and the multi-year capital improvement scenarios that drive municipal budgets.
Mature and mid-modernization.
API documentation is gated behind campus.cartegraph.com customer login, making discovery and onboarding hard for new integrators. API access may require additional license cost from the vendor beyond base subscription. Full sourced list under Sources below.
Common alternatives include Trimble Cityworks, Lucity (CentralSquare), IBM Maximo, Brightly Asset Essentials (Siemens), AssetWorks EAM, PubWorks. Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Cartegraph API and MCP server so AI agents and internal tools can read and write Cartegraph data. See the Cartegraph integration docs at supergood.ai/docs/cartegraph-api.
