Segment Analysis

By Service Model: FaaS APIs Accelerate Serverless Adoption

The Cloud API market size for SaaS integrations equalled USD 0.62 billion in 2024, equating to a 46% share. Enterprises rely on SaaS APIs to connect CRM, ERP, and collaboration suites. The Function-as-a-Service cluster increases at a 27% CAGR, the fastest within the Cloud API market. Developers value on-demand execution and granular billing, so serverless endpoints now underpin chatbots, streaming analytics, and AI inference. FaaS also reinforces event-driven patterns that decouple modules and shrink time-to-launch. IaaS and PaaS APIs remain essential for provisioning, but growth is slower because most infrastructure automation is already in place.  

Serverless adoption changes cost models; teams pay for invocations, not idle capacity. Business leaders view this as financial agility, aligning opex with revenue cycles. Yet the operational shift to stateless design challenges legacy monitoring tools. Vendors answer with integrated observability, offering trace visualisation that scales to billions of calls. The competitive field thus tilts toward platforms bundling compute, storage, and API lifecycle management, which locks in customers and sustains the Cloud API market revenue stream.

Public endpoints captured 63% of the Cloud API market share in 2024, thanks to hyperscale reach and mature ecosystems. Cost-effective regional PoPs support global rollouts, and pay-as-you-go models suit unpredictable traffic. Hybrid deployments rise 23.5% CAGR through 2030 as firms unite on-prem nodes with multiple clouds to satisfy latency targets and data-residency laws. Policy-driven routing tools and service meshes provide uniform security, so teams avoid rewriting business logic.  

Private clouds remain critical for classified workloads and industrial automation. Telecom operators also house APIs within network cores to monetise 5G slices. Multicloud control planes, delivered as managed services, synchronise policy enforcement across domains. The Cloud API market therefore pivots to federation features such as unified discovery and cross-cloud quotas, enabling businesses to exploit best-of-breed components without vendor lock-in.

By Enterprise Size: SMBs Drive Democratization Through Low-code Platforms

Large corporations continued to dominate spending, accounting for 58% of the Cloud API market size in 2024. They possess complex legacy estates and regulatory obligations that demand robust, audit-ready gateways. However, low-code and no-code tools now lower adoption barriers, so SMBs expand at a 22% CAGR. Component marketplaces with drag-and-drop connectors reduce the need for deep development skills. Consumption-based pricing aligns with variable revenues, supporting use cases from digital retail to regional logistics.  

As SMB adoption grows, platform vendors craft tiered offerings: self-serve portals for startups, guided onboarding for medium firms, and enterprise editions with SOC 2 certifications. This segmentation allows providers to capture the full value curve while keeping acquisition costs low. The influx of smaller customers diversifies the Cloud API market user base and drives community-led innovation.

By End-user Industry: Healthcare Transformation Accelerates FHIR Adoption

BFSI retained the top position with 22% of the Cloud API market share in 2024. Banks deploy open banking endpoints for account aggregation and real-time payments. Fintech partnerships rely on these APIs to differentiate through instant credit decisions. Healthcare and life sciences exhibit a 24% CAGR, the highest among industries, as providers roll out patient-facing apps, e-prescription services, and remote monitoring feeds. Standardised FHIR resources simplify cross-vendor data exchange, opening revenue opportunities for specialist integrators.  

Manufacturers integrate digital twins and predictive maintenance analytics through edge-optimised APIs. Media firms embrace GraphQL to tailor content bundles and reduce mobile payload sizes. Telcos expose network APIs for SMS, location, and quality-on-demand, turning infrastructure into a service. In every vertical, compliance dictates architecture, so domain-specific accelerators gain traction and further enlarge the Cloud API market.
