Market Opportunity
Hidden engineering cost: adapting existing APIs for AI agents targets a $40.0B = global API & developer tooling market (~25M software teams) x $1.6K avg annual spend on API tooling, integration & AI-agent readiness total addressable market with medium saturation and a year-over-year growth rate of 30%+ combined CAGR for API management, developer tools and AI developer platforms.
Key trends driving demand: Function-calling in LLMs -- enables programmatic, structured API invocation from natural language, creating a need for standardized tool specs and wrappers.; Agent adoption -- enterprises are piloting autonomous agents that require different QoS, auth, and safety rules than human developers.; API-first economy -- more internal and external microservices mean more targets for agent orchestration and integration work..
Key competitors include Postman, Kong (API Gateway/Kong Inc.), RapidAPI (Rakuten RapidAPI), LangChain / LangChain Labs, OpenAPI / Swagger (adjacent standard/workaround).
