Integrate Property Due Diligence Into Your Platform

Q: How do I get started with the API?

Sign up for a free developer account to receive sandbox API keys instantly. Explore the interactive API docs, test with our sandbox data, and when ready, upgrade to production keys. The entire process takes less than 5 minutes.

Q: What authentication method does the API use?

The API uses OAuth 2.0 with client credentials flow. You receive a client ID and secret, exchange them for a bearer token, and include the token in your request headers. Tokens are valid for 1 hour with automatic refresh support in our SDKs.

Q: Is there a rate limit?

Standard plans: 100 requests per minute, 10,000 per day. Growth plans: 500 requests per minute, 50,000 per day. Enterprise plans: Custom limits. All plans include burst allowance for temporary spikes. Rate limit headers are included in every response.

Q: How do webhooks work?

Register your webhook URL in the dashboard. When a property assessment completes, we send a POST request with the full results as JSON payload. Payloads are HMAC-SHA256 signed for verification. We retry failed deliveries up to 5 times with exponential backoff.

Q: Do you support batch submissions?

Yes. The batch endpoint accepts up to 100 properties per request. Each property in the batch receives an individual job ID and webhook callback. Batch status can be tracked via a single batch status endpoint.

Q: What happens when the API schema changes?

We use semantic versioning (v1, v2, etc.) for breaking changes. Non-breaking additions (new optional fields) are added without version bumps. We provide at least 6 months of overlap when deprecating a version, with migration guides and SDK updates released in advance.

Q: Can I trigger document collection and auto-start via API?

Yes. The Collection API lets you create Collector links programmatically and configure auto-start rules. When documents arrive via a Collector submission, reports can start automatically based on your STP configuration. Webhook callbacks notify you at each stage.

A single API that returns standardized property risk scores across title, encumbrance, litigation, compliance, and market dimensions. REST endpoints, webhooks, SDKs, and a sandbox, everything you need to ship fast.

Integration Challenges

Property Data Is the Hardest Data Problem in Real Estate

Fragmented data sources

Records sit across sub-registrar offices, revenue departments, courts and banks, each in its own format.

70+ searches behind one integration

Government searches across 14 states and 700+ courts come through a single API.

No standard property schema

Every state and authority follows different conventions, so your parsing code keeps growing.

A consistent report structure

Every case returns the same 29 sections, 29 risk signals and five-pillar rating, each finding cited to its source page.

Compliance is hard to build

Audit trails, accuracy and user privacy are a compliance engineering project on their own.

Cited, auditable, stored in India

Every finding links to its source. Data is stored in India and we are ISO/IEC 27001:2022 certified.

Your workflow

From first document to a grade you can act on.

01Collected
Get your API key
Get an API key and read the REST API documentation to map your fields.
02Collected
Create a case
Post the property and party details from your platform. Documents can arrive through a secure collector link.
03Running
Searches run
Government and court searches run in parallel. Status updates reach you by webhook.
04Queued

One API, Complete Property Intelligence

We Solved the Hard Problems So You Don't Have To

The LegiScore API abstracts away the complexity of Indian property data. One API call, standardized JSON response, five-pillar risk scoring. We handle data collection, normalization, analysis, and monitoring.

01Pillar
Ownership History
Ownership chain analysis returned as structured data with confidence scores for each ownership transfer.
02Pillar
Loans & Charges
Active and historical encumbrances with charge holder details, amounts, and discharge status.
03Pillar
Court Cases
Case details including court, case number, parties, filing date, status, and next hearing, all as JSON.
04Pillar
Approvals & Permits
Boolean compliance flags for each regulatory requirement with authority name and document references.
05Pillar
Market Conditions
Valuation data with confidence intervals, comparable transactions array, and market trend indicators.
