Pass callback_url on POST /api/enrich or
POST /api/enrich/batch to receive the terminal brief envelope via HTTPS POST
instead of polling GET /api/jobs/:id.
POST /api/enrich
Authorization: Bearer $UNIQUENESS_API_KEY
Content-Type: application/json
{
"linkedin_url": "https://www.linkedin.com/in/example",
"callback_url": "https://your-app.example/hooks/uniqueness"
}
Returns 202 {status:"accepted", delivery:"callback"} when the URL passes SSRF validation (public https only).
The same callback_url on POST /api/enrich/batch is applied to every
queued profile in the batch. Each terminal job posts its own envelope to your endpoint.
