Lightning Fast Transfers

Tap into high-performance cloud infrastructure to move data at speeds that leave standard protocols in the dust.

Enterprise-Grade Security

In-flight and at-rest encryption, password protection, and ISO 27001:2022 and SOC 2 Type II certification.

Granular Control

Auto-create and manage Portals, teams, permissions and more, giving developers full control over who can send and receive files.

Fully Automated Transfers, Right In Your Workflow

Building fast, reliable file transfer into existing tools and pipelines from scratch is costly and time-consuming, forcing development teams to divert resources instead of focusing on their core products and features.

The MASV API gives you everything you need to send and receive massive files, automate delivery workflows, manage users, connect to storage, and more. Use it to enable fully automated and integrated file delivery, right in your custom workflow, without reinventing the wheel.

Real-Time Webhooks

Event-driven webhooks fire the moment a file lands, enabling downstream automation without polling or manual checking.

No Limits

There are no limits on how large a file package can be or how many files can be in a package, providing a reliable foundation for high-res media and big data.

Accessible Dev Docs

Clean, well-structured documentation and straightforward authentication lets developer and engineering teams build fast and independently.

Relentless Reliability

Enterprise-grade infrastructure and infinite auto-retries from the point of failure ensure your transfers complete every time, with no dropped files.

Build Something Cool With the MASV API

Setting up the MASV API is simple:

  1. Create a MASV account.
