API Usage Policy
Effective date: 3 October 2026
This policy is part of the [Terms of Service](/terms).
Plans and limits
Plans, prices and limits (per minute, per day and per month, AI and Smart Research calls) are listed on the [pricing page](/pricing).
- Per-minute and per-day limits reset on their own.
- Monthly quotas reset on the 1st of each month (UTC). Unused quota does not roll over.
- Every response carries X-RateLimit-Remaining and X-DailyLimit-Remaining headers. Over a limit, the API answers HTTP 429; per-minute and per-day limits also send a Retry-After header.
Authentication
Send your API key in the Authorization header:
Authorization: Bearer bos24_...
Requests without a valid key receive HTTP 401. Keep keys out of public code and browsers.
Responses and pagination
All responses are JSON. List endpoints return data, total, page, per_page and total_pages, with at most 100 records per page.
Caching
You may cache responses for up to 5 minutes. Do not cache error responses.
Attribution
When you show data from the API to others, credit it as "Data © Dubai Land Department" and do not present it as official or government-endorsed. The [Data Attribution & Licensing](/data-license) page has the full wording.
Prohibited
- Sharing API keys with third parties
- Bypassing or attempting to bypass rate limits, quotas or authentication
- Downloading data at scale to rebuild, mirror or resell the underlying datasets
- Reverse engineering the API or its database
- Using data for spam or unsolicited communications, including using broker names or phone numbers from the /brokers endpoints for unsolicited marketing, bulk messaging or cold calling
- Presenting price estimates as formal valuations by a licensed valuer
Bulk access
For larger volumes or data feeds, email [email protected] about an Enterprise agreement.
Monitoring and suspension
We monitor usage for rate limits, abuse, performance and security. We may suspend keys that persistently exceed limits, break this policy or the Terms of Service, pose a security risk, or belong to accounts with unpaid fees.
