HakiChain API documentation and developer portal

HakiChain is a legal intelligence platform for professional legal teams. This developer portal helps agents and integrators discover the HakiChain public API surface, OpenAPI specification, authentication model, and MCP integration path before any customer-data integration is considered. HakiChain does not publish an unauthenticated API for customer matters, documents, or legal workspaces.

HakiChain OpenAPI specification

The HakiChain OpenAPI 3.1 specification documents the public discovery endpoint GET /api/v1/platform. It returns documentation links, the OpenAPI URL, agent instructions, and support contact information. Request Accept: text/markdown for a Markdown representation.

HakiChain public discovery API

GET https://hakichain.com/api/v1/platform requires no authentication. Example:

curl -s -H "Accept: application/json" https://hakichain.com/api/v1/platform

Unsupported public API paths return JSON errors with stable code, message, and hint fields, or Markdown when requested with Accept: text/markdown.

HakiChain API authentication

Public discovery endpoints require no credentials. Customer-data APIs for matters, documents, reminders, and workspaces require an approved integration and authenticated credentials issued by HakiChain. Contact info@hakichain.com for enterprise API access.

HakiChain MCP server

HakiChain provides a HakiLens MCP (Model Context Protocol) research server for approved enterprise integrations. MCP server access is not public; contact info@hakichain.com for MCP deployment credentials and supported tools.

Rate limits

The public discovery API allows 60 requests per minute per caller. Every response carries RateLimit, RateLimit-Limit, RateLimit-Remaining, and RateLimit-Reset. HTTP 429 responses include Retry-After.

Versioning and deprecation

The current URL version is /api/v1. Read the HakiChain API deprecation policy for Deprecation and Sunset header conventions.
