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: Nango (800+ APIs, without normalized data models), Unified.to (440+), StackOne (270+), Kombo (250+), Finch (250+, of which roughly 30 are automated API integrations), Merge (220+), Apideck (200+), Paragon (130+), Chift (100+), Rutter (60+), Codat (35+), Maesn (30+), Conductor (QuickBooks Desktop only). 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, Unified.to, Conductor ($49/month per connection), and Nango (usage tiers from $50/month) publish pricing on their pricing pages. Finch publishes its Starter tier ($65/month per connection) but its Pro and Premier plans are quote-only. 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, Unified.to, Conductor, Nango, and Finch 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, Unified.to, Chift, Conductor, and Nango ship a hosted (cloud) MCP endpoint. Paragon offers self-hosted only, Maesn is in beta self-hosted, and Finch ships a self-hosted npm package. 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. Nango offers self-hosting on its Enterprise tier. Apideck, Chift, and Maesn host in EU only. Rutter and Conductor are US only. Finch does not publish hosting regions.
- 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, last verified July 2026.
