A real answer from the API (22 Oct 2026), with the reading note left out. The Tamil name is printed as the register writes it.

What it returns

A parcel check returns is_waqf_land and the matching rows. A clear answer (is_waqf_land false) is a real answer and is charged.

Field	What it holds
`is_waqf_land`	true when the survey is recorded as waqf land; false when the register has no row for it.
`parcels`	Up to 10 rows: institution and institution_ta, waqf_id, gs_no, register_no, officer (the supervising office), village or town, block, taluk, district, survey and extent (as the register writes it).
`total_matches`	How many rows matched.
`survey`	The survey you asked about.
`institutions`	With waqf_name: up to five institutions matching the name, each with gs_no, register_no, officer, parcel_count and a sample of its parcels.
`message`	On a clear answer: what it does and does not establish.

Ways to call it

Check a survey, or list an institution's land.

Is this survey waqf land?

resolve_parcel gives the district, village and survey for a map point.

{"district": "Chennai","village": "Tondiarpet (Part 2)","survey_number": "3103","block": "0047"}

An institution's land

The name can be in English or Tamil.

{"waqf_name": "Shafi Mosque"}

Inputs

The JSON body of the POST is the arguments. Send a waqf_name, or a district with a village (and a survey number to check one parcel).

Argument	Type	What to send
`district`	string	The revenue district name, in English or Tamil.
`taluk`	string
`village`	string	The village, or the town for town survey land, in English or Tamil.
`survey_number`	string
`sub_division`	string
`block`	string	For a town survey number: its block, from the plot record.
`waqf_name`	string	Search by institution instead of by parcel, in English or Tamil.

Code

Set LANDLENS_KEY to your key. In an AI app, connect https://verified.realestate/mcp once and ask in plain words instead. In Postman, download this API's collection, import it (File, Import) and set apiKey.

curl -X POST https://verified.realestate/api/v1/tools/waqf_land \

Is town survey 3103, block 47, in Tondiarpet recorded as waqf land?

Your AI says the price, checks the Waqf Board register, and names the institution and its register number.

Responses

Every answer has the same envelope. What status can say for this call:

status	What it means
`ok`	The check ran: is_waqf_land is true or false, or the institution was found. Charged 1 credit.
`not_found`	No institution matches the name you sent, or neither a waqf_name nor a district or village was sent. Nothing is charged.

Where the data comes from

Register

The Tamil Nadu Waqf Board's register: the list of waqf institutions with their GS and register numbers and supervising office, and each institution's land parcels with survey number and extent.

Coverage

About 6,600 land parcels of about 5,500 waqf institutions across Tamil Nadu, village and town survey land, in our copy of the Board's register.

How current

The institution list is refreshed every 90 days. The land parcels are refreshed by a supervised run, since the Board's land search sits behind a captcha.

How we read it

Matched by district (every spelling, or the Tamil name), village or town (English or Tamil), and the old or new survey number. For town survey land, the block picks the row. The sub-division is not filtered on, so a neighbouring waqf sub-division shows too.

Who uses it

Buyers and brokers

Check a plot against the Waqf Board register before an advance is paid.

Law firms

Cite the institution, its GS number and register number in a title opinion.

Lenders

Screen collateral for waqf land before sanction.

Limits and good practice

A clear answer means the register has no row for the survey. It is a good sign, not a legal guarantee.
The sub-division is not filtered on. Read each row's survey against your own sub-division.
A town survey number repeats across blocks. Send block, or the answer may include another block's parcel.
Extent is given as the register writes it, without a unit.

Pricing

1 credit per answer

Each check costs 1 credit, whether it finds waqf land or comes back clear; nothing when a name matches no institution. Credits come from the same LandLens wallet as the chat and the minis. How billing works.

Calling at volume?

For thousands of calls a month, a portfolio sweep or a platform built on these registers, we quote a customised bulk price, with invoicing to match.
