Frequently asked questions
CapLinked scores C on the API Report Card. A self-serve REST API: free developer account (GitHub signup works), immediate API key, sandbox, and a $500 production credit. Auth is HMAC request signing over TLS, and official SDKs ship for Python, Node, Ruby, and C#.
CapLinked has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood.
CapLinked is an enterprise virtual data room (VDR) for secure document sharing, due diligence, fundraising, and M&A.
Virtual Data Rooms, Typically for M&A, capital raising, real estate, legal/compliance, life sciences, healthcare, and energy teams managing confidential deal documents. Deal teams create data rooms, upload and permission sensitive files, invite external counterparties, track engagement, and run audit reports during diligence/fundraising; developers embed VDR capabilities into their own apps via the API.
Claims $100B+ in transactions annually and use by ~45% of Fortune 1000; holds ISO 27001, SOC 2 Type II, HIPAA, PCI, FISMA. Solid Capterra/TrustRadius footprint, though smaller than market leaders like Datasite/Intralinks.
Yes, Holds confidential deal documents, permissions, and audit trails. But the data is reachable via a self-serve, SDK-backed API, so it is not trapped.
Founded ~2010; modern cloud SaaS, actively maintained, with current security certifications and a developer-facing API program.
None material found, API is documented, self-serve, and SDK-backed. Uploading large files is slow and time-consuming. Full sourced list under Sources below.
Common alternatives include Datasite, Intralinks (SS&C), iDeals, Firmex, Ansarada. Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial CapLinked API and MCP server so AI agents and internal tools can read and write CapLinked data. See the CapLinked integration docs at supergood.ai/docs/caplinked-api.
