Introduction

This section is where you can find our complete API reference, including request operations and responses.

Environments

We offer access to mainnets and testnets through the following hosts/root endpoints (occasionally referred to as customerApiDomain in our legacy docs):

• api.dfns.ninja (testnet)

• api.dfns.io (mainnet)

⭑ Note: These environments are fully segregated — on two distinct TLDs. As such, entities and authorization can NOT be used cross-environment.
