HakiChain API documentation and developer portal

HakiChain is a legal intelligence platform for professional legal teams. This HakiChain developer portal helps agents and integrators discover the HakiChain public API surface, OpenAPI specification, authentication model, MCP server path, and Deprecation/Sunset policy 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 (also at /openapi) documents the public discovery endpoint GET /api/v1/platform. It returns documentation links, the OpenAPI URL, agent instructions, deprecation policy URL, 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.

Documentation and agent guidance
