Upstream Data API

Request a sandbox key.

Tell us what you are building. We will issue a free key for synthetic responses and explain the separate review for scoped live access.

Four API contracts. Sandbox responses are synthetic. Live benchmarks can be withheld below the privacy threshold.

Tell us what you are building

A product idea, workflow, or endpoint need is enough. We do not need production traffic to start the conversation.

See the right data surface

We will point you to the endpoint shape, response contract, and sandbox path that fits your use case first.

Leave with a live sandbox path

You should know how to test the contract, what live access changes, and where data can be unavailable or withheld.

Awaiting reconciliation

Four synthetic scenarios with no patient data. Review the prepared work, approve and stage it, then see why the attempt remains open until external evidence is reconciled.

Start with the right sandbox path.

We will use the conversation to understand the workflow you are building, point you to the right API surface, and line up a clean path from sandbox to production access.
