The modern Unified API+MCP platform, built differently

Real-time, pass-through

Every request hits the source API live. No caching, no sync jobs, no stale data — just on-demand API reads/writes with native and virtual webhooks for instant updates.

Zero-storage by design

We never store end-customer data. Traffic is stateless and regionalized (US/EU/AU), reducing compliance scope and eliminating data-at-rest risk.

Unified APIs, deeply normalized

850+ integrations, 34 categories... Unified objects, endpoints, scopes, and errors—plus raw payload passthrough when you need integration-specific fields.

Custom fields & objects

Go beyond shallow schemas. We support custom fields and read/write on custom objects (e.g., Salesforce) via unified metadata APIs.

AI-ready integrations

Built for AI products: feed real-time data into embeddings or RAG pipelines, and let your agents perform secure write actions through MCP—all without caching or stale sync jobs.

Predictable pricing, no lock-in

Transparent usage-based pricing that scales with API volume—not customers. Own your credentials and migrate anytime.

Get integrations from backlog to production in days

1. Activate integrations

Enable integrations across 33 API categories, from Generative AI to Calendar and Verification

2. Launch integrations

Build, test, and launch multiple integrations simultaneously with only a few lines of code.

3. Authorize integrations

Embed our authorization component to let customers easily link their accounts.

Seamless authorization, no extra work

Unified removes the complexity of integration authorization so you can focus on building your product, not managing OAuth flows. Our pre-built UI and flexible API handle everything in the background—no extra setup required.

Seamless Scheduling, no extra work

Unified.to removes the complexity of scheduling meetings in your application, so you can focus on building your product, not managing scheduling.

Just use our pre-built VueJS or React components, and we will handle the rest. Using our Unified Calendar API to fetch FreeBusy times and to schedule meetings is a breeze, so you don't have to build your own scheduling solution.
