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 (1,300+, a count that includes MCP servers and authentication-only integrations), Nango (1,000+ APIs, without normalized data models), StackOne (550+ agent connectors), Kombo (250+), Finch (250+, of which roughly 30 are automated API integrations), Ampersand (240+ listed, about 150 with reads, without normalized data models), Merge (220+), Apideck (200+), Chift (150+), Paragon (130+), Rutter (60+), Codat (30+), 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, StackOne, Membrane, Unified.to, Conductor ($49/month per connection), and Nango (usage-based, 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. Kombo, Codat, Chift, Maesn, Paragon, Rutter, and Ampersand 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, and Ampersand lists SOC 2 Type 2 on its pricing page. 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 document a hosted MCP server their customers connect to without running it, and Ampersand documents a hosted MCP server in alpha. Paragon documents a self-hosted MCP server (Docker), Finch ships a self-hosted npm package, and Maesn publishes a repository you run yourself. Rutter announced an MCP server in October 2026 but has not documented a hosted endpoint. Kombo offers an MCP server for its documentation only, and we found no MCP server from Codat. Apideck also ships an MCP Explorer for browsing and running its MCP tools in the browser. * Which unified APIs support multi-region hosting or VPC deployments? Merge (US/EU/APAC, single-tenant available), Kombo (EU/US/Canada, per-account), StackOne (EU/US, multi-region), Codat (UK/US), and Unified.to (US/EU/AU, Enterprise on-prem) support multiple regions. Nango and Paragon offer self-hosting on their Enterprise tiers, and Membrane on its Business tier. Apideck and Chift host in the EU only; Maesn hosts in Germany with multi-region residency on Enterprise. Rutter and Conductor are US only. Finch does not publish hosting regions. Ampersand does not publish its default region and offers EU data residency and deployment in your own cloud account on its Enterprise plan. * How is the developer and agent experience scorecard calculated? We assess 17 dimensions and average only verified ratings, rounded to one decimal: llms.txt, MCP server, tool discovery, first-call discoverability, 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. Only ratings with dated, linked evidence enter the average. Missing evidence is Not verified, not a low score. Measured first-call time is reported separately.
