# API compliance documentation

> How Keldyn documents its HTTP APIs for compliance, integrations, and customer review.

Keldyn exposes authenticated HTTP APIs that power the product, the public Trust Center, and AI-agent integrations. This page explains how those APIs are documented for compliance and integration work.

## Surfaces

| Surface             | What it is for                                                                         |
| ------------------- | -------------------------------------------------------------------------------------- |
| **Product API**     | Authenticated REST API used by the Keldyn web app and integrations                     |
| **MCP server**      | Tooling interface for AI agents and IDEs (see [Keldyn MCP server](/keldyn-mcp-server)) |
| **Web application** | Primary user interface for managing use cases, controls, and evidence                  |
| **Trust Center**    | Public-facing compliance portal for your customers and prospects                       |

The product API is described with an **API specification** (OpenAPI). That specification lists available paths, request and response shapes, and authentication requirements for integration and review.

## Access

* Product and MCP APIs require authentication except for explicitly public endpoints (for example published Trust Center pages).
* Access to tenant data is authorized according to the signed-in user’s team and permissions, or the credentials issued to the integrating client.

## Using this for compliance

When an auditor or customer asks for API documentation:

1. Share this page as the overview.
2. Provide the API specification for the product API (available from your Keldyn workspace or account contact).
3. For agent and IDE integrations, also share [Keldyn MCP server](/keldyn-mcp-server).
4. For public Trust Center surfaces, see your published Trust Center and [Evidence & audits](/evidence-and-audits).
