Purpose of Documentation

The goal is to provide a new customer, platform or custodian a clear path to integrating with the Zero Hash ecosystem. One of Zero Hash's main philosophies is 'maximum flexibility,' and so this document will not only provide you with the complete set of API endpoints and connectivity options that are available, but also suggested implementations to help you think about which parameters are most applicable to your use case.

Generally, trades can be submitted either through our REST API or our FIX Straight Through Processing (STP) gateway.

General Information

Contact Information


Zero Hash provides two distinct environments: Production and Certification.


The Production environment exists for operating a live platform, submitting trades, managing deposits and withdrawals, and managing customers on your platform. It is recommended that applications conduct trial runs in the certification environment before executing live trades and consuming live market data.


Zero Hash operates 24/7.

Production Connectivity


Zero Hash has a Certification Environment which offers full settlement functionality using test funds. All funds are for testing purposes only.

The certification environment is available for applications to prove out and certify their readiness to work with Zero Hash systems.

New features and API changes are deployed in this environment and provide platforms the ability to test system updates prior to the changes moving into production.


Zero Hash operates 24/7. Note, however, that the certification environment will periodically be taken down for testing.
