A real answer from the API, with balance_after and request_id left out.

What it returns

One call, one answer. found is false (status not_found) when nothing in the library matches, and error says what the library does cover.

Field	What it holds
`records[]`	Up to 20 documents: document (its name), form_code and reference where it has one, authority, category (form, act, rule, circular, checklist or guide), purpose, detail_url (the page that explains it) and pdf_url.
`count, total_matches`	How many documents are in records, and how many matched in all. Name the form or Act to narrow a long list.
`query`	What was searched, with the filters you set.
`note`	How the query was read (phrase or key words), how to cite a circular, and a reminder to confirm fees and portals before filing.
`filtered_out`	On a miss under a filter: how many documents match the same words with the filter off.

Inputs

The JSON body of the POST is the arguments. Nothing is required by the schema, but send at least one of query, authority or category.

Argument	Type	What to send
`query`	string	Free text: a form letter ("Form M"), a document name ("TNCDBR", "Apartment Ownership Act"), or the purpose ("complaint", "agent registration", "layout checklist").
`authority`	string: rera, cmda	"rera" for the real estate regulator and its Appellate Tribunal, "cmda" for CMDA. Leave it out to search both.
`category`	string: form, act, rule, circular, checklist, guide	One kind of document: form, act, rule, circular, checklist or guide.

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/statutory_form \
  -H "Authorization: Bearer $LANDLENS_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query":"CMDA layout checklist"}'

import os, requests

r = requests.post(
    "https://verified.realestate/api/v1/tools/statutory_form",
    headers={"Authorization": f"Bearer {os.environ['LANDLENS_KEY']}"},
    json={
        "query": "CMDA layout checklist"
    },
    timeout=15,
)
body = r.json()
print(body["status"], body["credits_charged"], body["data"])

const res = await fetch("https://verified.realestate/api/v1/tools/statutory_form", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.LANDLENS_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    "query": "CMDA layout checklist"
  }),
});
const body = await res.json();
console.log(body.status, body.credits_charged, body.data);

I want to complain about a builder who has not handed over my flat. Which form do I file, and where is it?

Your AI finds the complaint form, says which authority it goes to, and gives you the PDF.

Responses

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

status	What it means
`ok`	At least one document matched.
`not_found`	Nothing in the library matches, an authority or category value was not recognised, or no input was sent. error says which, and what the library covers.
`free_limit_reached`	Your account has used its free calls for the hour or the day. retry_after says when they come back.

Where the data comes from

Register

A library of the forms, Acts, Rules, checklists, circulars and guidance the Tamil Nadu real estate regulator and the Chennai Metropolitan Development Authority publish, each kept as a PDF with a page that explains it.

Coverage

60 documents: 28 from the real estate regulator and its Appellate Tribunal (forms A, B, E, J, L, M and N, the 2016 Act, the 2017 Tamil Nadu Rules, the Regulations, circulars, the building application checklist and the registration guidelines) and 32 from CMDA (application checklists for planning permission, layouts and reclassification, the 2019 building rules and amendments, the Town and Country Planning Act, the Apartment Ownership Act 2022, TDR and regularisation guidelines, inspection SOPs and orders). Forms of DTCP, the revenue department, corporations and TANGEDCO are not held.

How current

The library changes when an authority publishes a new form or rule and it is added. Fees, filing portals and deadlines change more often than the forms, so confirm them with the authority before filing.

How we read it

The query is matched as a phrase first, then through common synonyms (a "building permit" is planning permission), then by its key words, keeping only the best-scoring documents. Forms you can file come first, then checklists, rules, Acts, guides and circulars.

Who uses it

Homebuyers

Find the right complaint or appeal form against a builder, with the PDF, without hunting through the regulator's site.

Developers and architects

Pull the current CMDA checklist and building rules for a planning permission or layout application.

AI assistants

Answer "which form do I file" with the actual document and its link, not a description of one.

Limits and good practice

Two authorities only: the Tamil Nadu real estate regulator and CMDA. DTCP, revenue, corporation and electricity forms are not in the library.
Some circulars are scanned PDFs. Cite a circular by its reference and link the PDF rather than relying on its title.
This returns the document to file. To check whether a project, promoter or building is registered or approved, use the approval tools.
Deed formats (sale, gift, lease, power of attorney) are drafted with document_draft, not held here.

Pricing

Free

The forms library costs nothing. Free calls are subject to the account's hourly and daily allowance. 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 for TN RERA and CMDA forms?

Yes. LandLens returns the matching forms, rules, checklists and circulars with their PDF links as JSON, over plain HTTPS or as an MCP tool. It is free.

Can I ask in plain words?

Yes. "Which form do I file to complain about a builder" is read by its key words and returns Form M, the complaint before the regulator; a form letter or a document name works too.

Which documents does it hold?

60 documents: 28 from the real estate regulator and its Appellate Tribunal and 32 from CMDA, including the 2019 building rules and the planning permission checklists.

Does it tell me the filing fee?

No. Fees and filing portals change more often than the forms; confirm them with the authority before filing.
