From model call to signed record in 10 minutes.

Four SDKs. One contract. Open-source verify CLI. Every integration you'd expect, wrapped in one line.

Start here

The quickstart walks a first-time engineer from install to a signed, logged, verifiable decision in ten minutes. No background in cryptography required. No custom evidence schema to learn.

v = Veridra(tenant_id="your-tenant")

receipt = v.attest(

inputs={...},

outputs=openai_response,

model="gpt-4o"

veridra-verify CLI · Open source

Verify without trusting us.

An auditor, regulator, or curious engineer can verify every signature and every log inclusion with our open-source CLI. They do not need Veridra's cooperation. They do not need Veridra's servers to be running. The evidence stands on its own cryptography.
