## Request

Create response

```
POST /{harness_id}/v1/responses
Idempotency-Key: <uuid>
Content-Type: application/json

{
  "input": "Review this uploaded agreement and return a checklist.",
  "stream": true
}
```

## Boundary

Send runtime work, not product-building work. For example, send one contract review task, not a request to build the contract review product.

**Open standard**

The create-response call shown here is HarnessRouter's implementation of the UHP task endpoint, where one unit of work goes in and a response object comes out.See [UHP's Tasks chapter](https://unifiedharnessprotocol.org/spec/tasks).
