Agari
Agari is an email-security provider that pioneered and helped author the DMARC email-authentication standard to protect organizations from phishing, business email compromise (BEC), email spoofing, and brand impersonation. Founded in 2009, Agari was acquired by HelpSystems (now Fortra) in May 2021 and is delivered as Fortra's email-security portfolio, including DMARC Protection / Brand Protection, Phishing Defense, and Phishing Response. The Agari Platform exposes a RESTful JSON API secured with OAuth 2.0 Client Credentials for retrieving security telemetry, auditing users and domains, tracking DMARC policy enforcement, and integrating Agari data into SIEM and SOAR tooling. It was originally backed by Norwest Venture Partners and other venture investors before its acquisition.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Agari the way a machine reads it — 3 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Agari scores 18.4/100 (emerging), with a separate agent-readiness read of 17/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Agari
Each block below is one kind of artifact we hold for Agari. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 1
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Agari Platform API
RESTful JSON API for the Agari Platform, secured with OAuth 2.0 Client Credentials. Provides access to Agari email-security telemetry — alerts, domain tracking, DMARC policy-enf...
Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
