API, Platform & Developer Agreements

The Contracts That Power the Platform Economy

APIs are the connective tissue of modern software — and the legal agreements that govern API access, platform participation, and developer ecosystems are increasingly where business value is created and protected. Whether you’re a platform company opening your APIs to third-party developers, a business building on another company’s platform, or an enterprise integrating multiple APIs into your technology stack, the contractual framework matters. John Montague has advised technology companies on platform and developer agreements for over fifteen years, bringing a transactional perspective shaped by his work at Locke Lord LLP (now Troutman Pepper Locke), an AM Law 200 firm, and deepened by years of representing SaaS companies, fintech platforms, and developer-focused technology businesses.

Tip from John Montague: API terms of service are contracts, even when they don’t feel like one. If your business depends on access to a third-party API, you need to read those terms the way you’d read any commercial agreement — because they contain rate limits, usage restrictions, IP assignments, and termination provisions that can fundamentally affect your product roadmap. I’ve worked with companies that built their entire product on an API that the provider later restricted or deprecated. That risk should be identified and managed contractually from day one.

How We Help

Montague Law advises platform companies, API providers, and developers on the contractual architecture of technology ecosystems. John Montague’s work includes drafting API terms of service and developer agreements that protect the platform’s IP and commercial interests while attracting a thriving developer ecosystem; negotiating enterprise API access agreements with appropriate rate limits, SLAs, data usage restrictions, and pricing mechanisms; structuring platform partnership agreements for companies building integrations, marketplace listings, or embedded solutions on third-party platforms; advising on data rights and usage restrictions in API relationships, including the intersection of API terms with data privacy regulations; drafting developer program terms, marketplace policies, and app review guidelines for platform companies building developer ecosystems; and counseling on the IP implications of API design, including questions of copyrightability, interoperability rights, and the legal boundaries of clean-room reimplementation.

Platform Law Is Still Being Written

The legal frameworks governing APIs and platforms are among the most rapidly evolving areas of technology law. Questions about API copyrightability, platform liability for third-party developer conduct, and the enforceability of unilateral terms-of-service changes have produced significant litigation and regulatory attention in recent years. For companies whose business models depend on platform access or API availability, these legal developments have direct commercial implications.

John Montague approaches platform and API agreements with the understanding that these relationships are fundamentally asymmetric — the platform typically controls the terms, the access, and the ability to change both. For developer clients, this means negotiating agreements that provide meaningful access protections, change notification requirements, and data portability rights. For platform clients, it means drafting terms that are enforceable, commercially reasonable, and sufficiently clear to avoid disputes with the developer community.

His venture capital practice adds relevant perspective: platform businesses and API-dependent companies are among the most common models in the startup ecosystem. Investors evaluate the strength and stability of a company’s platform relationships during diligence, and John’s experience advising both platforms and the companies that build on them gives him insight into how these relationships are assessed from an investment perspective.

Frequently Asked Questions

What should an API terms of service include?

A well-drafted API terms of service should address scope of permitted use and use restrictions, rate limits and usage quotas, authentication and security requirements, data ownership and usage rights (especially for data flowing through the API), IP ownership of the API itself and any developer-created integrations, SLA commitments (if any), modification and deprecation policies with reasonable notice periods, termination rights and data portability, liability limitations and indemnification, and compliance with applicable regulations.

How do I protect my business if it depends on a third-party API?

Start by understanding the terms of API access — not just the technical documentation, but the legal terms of service. Key protections to negotiate (where possible) include minimum notice periods for API changes or deprecation, SLA commitments for uptime and performance, data export and portability rights, restrictions on the provider’s use of your data, and clear termination provisions with transition periods. For critical API dependencies, John Montague also advises building technical redundancy and contractual backup plans.

Does Montague Law work with platform companies building developer ecosystems?

Yes. John Montague advises platform companies on the full legal architecture of developer programs — from API terms of service and developer agreements through marketplace policies and partner program terms. His approach balances the platform’s need for control and IP protection with the commercial reality that successful platforms depend on a healthy, engaged developer community.
