Healthcare’s integration backbone.
A real-time read and write API for leading ambulatory EHRs — including the ones with no public interface.
Powering the teams building the future of healthcare.
A few of the teams we’re proud to support.
You can build it yourself. Or you can ship.
Every health tech team faces the same choice when it comes to EHR integrations.
Build from scratch
- ✕12–18 months of work
- ✕Dedicated integration team
- ✕Different code per system
- ✕No access to closed systems
- ✕Ongoing maintenance burden
Legacy middleware
- ✕Months of procurement
- ✕Rigid, outdated data models
- ✕Read-only in most cases
- ✕Not built for startups
- ✕Enterprise pricing and timelines
The unified API
- ✓Deploy in days
- ✓One API across EHRs
- ✓Real-time read and write
- ✓Access to closed systems
- ✓Built for fast-moving teams
One API. Every system.
Cobalt normalizes access to the fragmented layer of ambulatory EHRs, including the systems with no public APIs. Read and write through a single interface — same endpoints, same auth, same response shape, regardless of what your customer is running.
Real-time read and write
Not batch jobs. Not overnight syncs. Book appointments, file chart notes, and pull lab results the moment they happen — with full write access to systems that most vendors can only read from.
Systems with no public API
eClinicalWorks, PracticeFusion, ModMed, healow, and the long tail of ambulatory platforms that never shipped an API your team could build against. Cobalt does the reverse engineering, once, for everyone.
Normalized data model
One patient schema. One appointment schema. One note schema. When you add your next EHR, you add a flag — not another integration team.
Live the same day
Sign up, get your API keys, and make your first real request in under an hour. No scoping calls, no statements of work, no procurement cycle blocking your roadmap.
The teams building healthcare.
Companies that need real-time read and write access to EHRs use Cobalt as their integration infrastructure. They build the product; we handle the EHR connectivity.
AI-native healthcare companies
AI scheduling, voice AI, and clinical automation companies that need to read and write to EHRs on day one. Getting write access via API typically takes weeks or months; with Cobalt, it’s same-day.
- ›Get provider availability, create and update appointments
- ›Create patients and prescription refills
- ›Read and write chart notes across EHR systems
Billing and services companies
Outsourced billing, claims processing, and coding companies that need structured data out of EHRs to automate RCM workflows. A $50B market that runs on manual data extraction; Cobalt changes that.
- ›Extract claims line items, payments, and adjustments
- ›Build financial ledgers from structured EHR data
- ›Automate data transfer for coding, denials, and follow-ups
PE-backed practice groups
Multi-site practice groups that need standardized EHR integration across 50, 100, or 200+ clinics. Replace per-clinic custom builds with one API that scales with every acquisition.
- ›Standardize integration across every clinic in the portfolio
- ›New acquisitions go live in days, not months
- ›Predictable per-clinic pricing that scales linearly
Augmenting an existing EHR API
When your EHR has an API but it doesn’t do everything you need, and the new endpoint is six months out. Cobalt fills the gaps, right away.
- ›Add read/write capabilities the native API doesn’t support
- ›Ship features without waiting on EHR vendor timelines
- ›One consistent API across native and augmented endpoints
