EC Availability API: which office holds a village, and since when

Yes. The LandLens EC availability API takes a registration village name and returns every Tamil Nadu sub registrar office that has held a village of that name, with the period each held it, the office code, and whether it still does. Villages move between offices over the years, so an encumbrance certificate from 1985 may need a search at a different office from one for 2020; this tells you which. It costs nothing.

A real answer from the API. Four of the twelve periods are left out for length; the rest are as returned. Several different villages in Tamil Nadu are called Kavanoor, and their offices come back together.

What it returns

One call, one answer. found is false (status not_found) when no registration village carries a name like the one sent.

FieldWhat it holds
villages[]Up to four registration village names that match, each with its ranges.
villageThe village name exactly as the registration department writes it, which is the spelling an encumbrance search needs.
ranges[].sro, ranges[].sro_codeThe sub registrar office and its code for one period.
ranges[].from, ranges[].toWhen that office's records for the village begin, and end when it gave the village up. No to means the period is open.
ranges[].currentWhether the department lists that office as currently holding the village.
noteHow to read the ranges.

Inputs

The JSON body of the POST is the arguments.

ArgumentTypeWhat to send
villagerequired string The village name as the registration department knows it, e.g. Kavanoor. sro_directory or sro_lookup give the registration spelling when the revenue spelling differs.

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.

Responses

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

statusWhat it means
okAt least one registration village matched. Read every range; a village can have several offices over time.
not_foundNo village carries a name like that, or no name was sent. Try the registration spelling from sro_directory.
free_limit_reachedThe account has used its free calls for the hour or the day. retry_after says how many seconds to wait; paid calls keep working.

Where the data comes from

Register

The Tamil Nadu Registration Department's list of villages under each sub registrar office, with the dates from which each office's encumbrance records for the village begin and, where it gave the village up, end.

Coverage

25,770 registration village names across 627 sub registrar offices, statewide, with 31,293 office periods between them.

How current

A copy taken from the department's encumbrance search and reviewed once a year. Office boundaries change rarely; when a village moves, the new office appears as a new period.

How we read it

The name is matched without regard to case. Every office period on the matching names is returned as it is recorded; nothing is inferred.

Who uses it

Advocates tracing a title

Know before ordering a 30-year EC that the early years sit at another office, and order both.

EC ordering tools

Split a long EC request into one search per office period, so no years fall between offices.

Lenders

Check that an EC on file was taken at the office that actually held the village for the years it claims to cover.

Limits and good practice

  • The match is by name only. Many Tamil Nadu villages share a name, and the offices of all of them come back together. Pick the ranges by the office you expect for the district, or confirm with sro_lookup on a map point.
  • At most four matching village names are returned.
  • The registration spelling can differ from the revenue spelling (for example Kunrathur and Kundrathur). If nothing matches, look the village up in sro_directory first.
  • A period says where the records are held, not that any deed was registered in it.

Pricing

Free

EC availability costs nothing. Free calls have their own allowance per hour and per day, counted across every key and connected app on the account, and it is larger once the account has bought credits. Credits come from the same LandLens wallet as the chat and the minis. How billing works.

Calling at volume?

Free calls have an hourly and daily allowance. For more than that, or a platform built on these registers, we set up limits and a plan to match.

Questions

Is there an API to find which sub registrar office holds my village?

Yes. This one returns every office that has held a village of that name, with the period and office code. sro_lookup answers the same question for a map point, and sro_directory for a village name with its namesakes flagged.

Why does my village show more than one office?

Either the village moved between offices over the years (each period then has its own office), or several villages share the name. Check the dates and the district of each office.

How far back do the periods go?

As far as the department records them. Most periods begin on 1 January 1975; a few hundred begin earlier, and later ones mark the date a village moved to a new office. If the years you need start before the earliest from date, they are not in the online records for that office.

Does this tell me whether there were any transactions?

No. It tells you where the records are kept for each period. ec_transactions reads the entries themselves.
