How OQVYN works

Go from agent action to verifiable audit evidence in three steps.

1

Register your agent

Create an agent in OQVYN and use its developer credentials in your workflow.

2

Record important actions

Send structured action data to OQVYN and create a cryptographically protected receipt.

3

Verify and audit

Check receipt integrity, signatures and chain continuity whenever you need evidence later.

Verifiable evidence

What an OQVYN receipt looks like

Receipts capture structured information about an agent action together with the data OQVYN uses for integrity and chain verification.

Integrity Detect whether recorded receipt data changed.
Chain continuity Link receipts into an ordered verification chain.
Verification Re-check receipt proof when reviewing an action.

Simplified example data. Field names shown here come from OQVYN's real receipt response schema.
