# Paramark

> Paramark is a marketing measurement and forecasting platform for growth and finance teams. It
> combines marketing mix modeling (MMM), incrementality testing and scenario planning to quantify
> the true incremental contribution of marketing spend across search, social, TV and
> out-of-home — rather than relying on last-touch attribution. Founded in 2022 by Pranav Piyush
> and Pete Belknap, backed by Greylock.

## What is true about Paramark's API surface

Paramark runs a production API host at `https://api.paramark.com` (uvicorn / FastAPI). It is
live — `GET https://api.paramark.com/healthz` returns `200 {"status":"ok"}` anonymously — but its
contract is not public. `GET https://api.paramark.com/openapi.json`, `/docs` and `/redoc` all
return `401` with `www-authenticate: Basic`. There is no developer portal, no API reference and no
published OpenAPI at any URL on any Paramark host.

API access is sold, not self-served: the pricing page attaches "API, MCP servers (coming soon)"
to the Advanced ($150k/yr) and Enterprise ($220k/yr) tiers. The MCP servers are announced, not
shipped — no MCP endpoint answered on any probed host as of 2026-08-12.

What Paramark does publish anonymously and machine-readably is its identity layer.

## Identity and authorization

- [OpenID Connect discovery](https://signin.paramark.com/.well-known/openid-configuration):
  issuer `https://signin.paramark.com`; authorization, token, userinfo, introspection, device
  authorization and JWKS endpoints; RS256 ID tokens.
- [OAuth 2.0 authorization server metadata](https://signin.paramark.com/.well-known/oauth-authorization-server):
  PKCE `S256`, dynamic client registration at `/oauth2/register`, device code grant.
- Grants: `authorization_code`, `client_credentials`, `refresh_token`,
  `urn:ietf:params:oauth:grant-type:device_code`.
- Scopes: `openid`, `profile`, `email`, `offline_access`. No product- or resource-scoped
  permissions are advertised.
- No `/.well-known/oauth-protected-resource` is served on the API host, so an agent cannot
  discover from `api.paramark.com` which authorization server protects it.
