UID2 Conversion Endpoint

A new endpoint converts hashed email identifiers (HEMs) to UID2 tokens for use with UID2-compatible DSPs and data partners.

POST /uid2/convert

Request:

curl -X POST https://apiv3.delivr.ai/uid2/convert \
  -H "Authorization: Bearer YOUR_API_TOKEN" \
  -H "X-Project-Id: YOUR_PROJECT_ID" \
  -H "Content-Type: application/json" \
  -d '{
    "hems": [
      "a1b2c3d4e5f6...",
      "f6e5d4c3b2a1..."
    ]
  }'

Parameters:

Field	Type	Required	Description
`hems`	string[]	Yes	Array of SHA-256 hashed email addresses

Response (200 OK):

{
  "results": [
    {
      "hem": "a1b2c3d4e5f6...",
      "uid2": "AgAAAAN...",
      "status": "success"
    },
    {
      "hem": "f6e5d4c3b2a1...",
      "uid2": null,
      "status": "not_found"
    }
  ],
  "total": 2,
  "converted": 1
}

Status values: success (UID2 token returned), not_found (no matching identity), error (conversion failed).

Rate limits: 1,000 HEMs per request, 10 requests per second.

Intent API

The Intent API is now available for external use. Query intent signals by company, domain, or contact to retrieve topic-level research activity.

GET /intent/signals

Request:

curl "https://apiv3.delivr.ai/intent/signals?domain=example.com&days=30" \
  -H "Authorization: Bearer YOUR_API_TOKEN" \
  -H "X-Project-Id: YOUR_PROJECT_ID"

Query parameters:

Parameter	Type	Required	Description
`domain`	string	One of domain/company/hem required	Company domain to query
`company`	string	One of domain/company/hem required	Company name to query
`hem`	string	One of domain/company/hem required	SHA-256 hashed email
`days`	integer	No	Lookback period in days (default: 30, max: 90)
`min_strength`	string	No	Minimum signal strength: `low`, `medium`, `high` (default: `low`)
`limit`	integer	No	Max topics returned (default: 50)

Response (200 OK):

{
  "domain": "example.com",
  "company": "Example Corp",
  "signals": [
    {
      "topic_id": "4eyes_115481",
      "topic_name": "Cloud Computing",
      "category": "Business",
      "signal_strength": "high",
      "first_seen": "2026-02-01",
      "last_seen": "2026-02-25",
      "event_count": 47
    }
  ],
  "total_signals": 1
}

Signal strength levels:

high - Significant increase in research activity above baseline
medium - Moderate research activity detected
low - Some research activity detected
