Frequently asked questions
- What is a unified API?
- A unified API normalizes many third-party APIs in the same category (CRM, accounting, HRIS, ATS, etc.) behind a single data model. You write your integration once against the unified schema and your customers can connect any supported provider, instead of you maintaining a separate integration per vendor.
- Which unified API has the most connectors?
- By raw count: Unified.to (440+), StackOne (270+), Kombo (250+), Merge (220+), Apideck (200+), Paragon (130+), Chift (100+), Rutter (60+), Codat (35+), Maesn (30+). Membrane claims 100,000+ AI-generated integrations on demand. Connector count is one signal; depth (per-connector CRUD parity) and category fit usually matter more.
- Which unified APIs publish pricing?
- Apideck, Merge, Kombo, StackOne, Membrane, and Unified.to publish pricing on their pricing pages. Codat, Chift, Paragon, and Rutter are quote-only. Apideck prices per consumer (end-customer connection) with unlimited calls.
- Which unified APIs are SOC 2 Type II certified?
- Apideck, Merge, Kombo, Codat, Paragon, Rutter, StackOne, Membrane, and Unified.to all hold SOC 2 Type II per their public security pages. Chift and Maesn list ISO 27001 + GDPR but no public SOC 2 Type II.
- Which unified APIs offer a hosted MCP server for AI agents?
- Apideck, Merge, StackOne, Membrane, and Unified.to ship a hosted (cloud) MCP endpoint. Paragon and Chift offer self-hosted only. Maesn is in beta self-hosted. Kombo, Codat, and Rutter do not currently expose an MCP server.
- Which unified APIs support multi-region hosting or VPC deployments?
- Merge (US/EU/APAC, single-tenant available), Kombo (EU/US, per-account), StackOne (EU/US, multi-region), Codat (UK/US), and Unified.to (US/EU/AU, Enterprise on-prem) support multiple regions. Apideck, Chift, and Maesn host in EU only. Rutter is US only.
- How is the developer and agent experience scorecard calculated?
- Each platform receives an unweighted average of 17 dimension scores rounded to one decimal: llms.txt, MCP server, tool discovery, time-to-first-call, sandbox, OpenAPI quality, SDK breadth, interactive try-it, webhook setup, error responses, docs search, code examples, changelog, versioning, free production access, connector breadth, and connector depth. Each score is sourced from the vendor's own public docs in April 2026.
