# Hydratic developer resources

Hydratic is the enterprise AI agent platform. This page is the machine- and human-readable index of developer resources on hydratic.ai: the public HTTP API this marketing site actually exposes, the OpenAPI specification, authentication (none on this host), error formats, and how that relates to the Hydratic product. It exists so agents searching for “Hydratic API”, “Hydratic OpenAPI”, “Hydratic docs”, or “Hydratic developer” can find a stable URL instead of a JavaScript marketing shell.

## Public API on hydratic.ai

These endpoints are reachable without a web UI and without credentials. They describe this marketing site. They are not a fake product API.

- `GET https://hydratic.ai/api/health` — liveness JSON for this host
- `GET https://hydratic.ai/api/site` — public read model (brand, pages, discovery URLs, product-API boundary)
- `POST https://hydratic.ai/api/lead` — contact/lead intake for the marketing site (rate-limited)
- `GET https://hydratic.ai/openapi.json` — OpenAPI 3.1 document for the endpoints above
- `GET https://hydratic.ai/api/openapi.yaml` — same specification as YAML

## OpenAPI specification

The canonical spec is GET /openapi.json. YAML is at GET /api/openapi.yaml. It documents health, the site index, lead intake, and the spec itself. It does not invent Hydratic runtime routes that are not served here.

## Authentication and scoped permissions

This landing site has no authenticated API. There are no OAuth scopes, API keys, or role-based credentials to request on hydratic.ai. Public discovery endpoints require no Authorization header; sending one is ignored. Tenant identity, connector credentials, and product authorization live in the Hydratic application, which is not served from this domain. We did not add a parallel auth system on the marketing site.

## Hydratic product API

Runtime APIs for Hydratic agents, connectors, approvals, and tenant data are not published as HTTP routes on hydratic.ai. This marketing repository only documents and exposes what this site actually is. If you need the product, use the contact form or the developer notes here; do not assume undocumented REST or GraphQL on this host.

## MCP and webhooks

This marketing site does not host an MCP server or webhook receiver. There is nothing to authenticate against for those protocols on hydratic.ai. If Hydratic ships MCP or webhooks, they will belong to the product application, not this domain.

## Agent discovery

Key pages honor Accept: text/markdown on the same URL and set Vary: Accept. Sibling .md URLs also work. Start with llms.txt, then the OpenAPI spec, then this page.
