Common Paper

Common Paper is a contract management platform that helps revenue, legal, and operations teams build, negotiate, sign, and manage commercial agreements in minutes using a library of committee-drafted standard agreements (Cloud Service Agreement, Mutual NDA, DPA, BAA, Professional Services, Partnership, Software License, Pilot, Design Partner, and Letter of Intent) paired with AI-assisted contract review. The company exposes a public REST API at api.commonpaper.com/v1 with Bearer-token authentication, JSON:API read responses, Ransack filtering, offset pagination, a documented webhook catalog, an agentic account-provisioning flow, and an official hosted MCP server plus a published Claude agent skill, so agents and integrations can list, create, send, void, reassign, and download agreements and templates programmatically.

Common Paper publishes 1 API on the APIs.io network. Tagged areas include Company, Contracts, Contract Management, Legal Tech, and Agreements.

The Common Paper catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Common Paper’s developer surface includes documentation, API reference, getting-started guide, authentication, support, engineering blog, pricing, and 19 more developer resources.
