Sublime Security
Sublime Security is an adaptive, programmable email security platform that combines best-in-class detection effectiveness with deep visibility and control. Teams write detection-as-code in Sublime's Message Query Language (MQL) to stop business email compromise (BEC), credential phishing, malware, and other email attacks, and can hunt retroactively across historical messages. Sublime runs as a managed multi-region cloud service or self-managed on Docker, AWS, or Azure, integrates with Microsoft 365, Google Workspace, and IMAP, and exposes a REST Platform API (v0), outbound webhooks, SCIM 2.0 provisioning, a Multi-Tenancy API for MSPs, and a free Analysis API with an open rules community. Backed by Index Ventures and IVP.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Sublime Security the way a machine reads it — 22 machine-readable artifacts across 16 APIs, 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 — Sublime Security scores 45.6/100 (developing), with a separate agent-readiness read of 36/100 (agent ready). 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 Sublime Security
Each block below is one kind of artifact we hold for Sublime Security. 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 16
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.
Sublime Security BinExplode API
The BinExplode API from Sublime Security — 2 operation(s) for binexplode.
Sublime Security Email Bombs API
The Email Bombs API from Sublime Security — 3 operation(s) for email bombs.
Sublime Security Enrichment API
The Enrichment API from Sublime Security — 1 operation(s) for enrichment.
Sublime Security Events in the audit log API
The Events in the audit log API from Sublime Security — 3 operation(s) for events in the audit log.
Sublime Security Hunt Jobs API
The Hunt Jobs API from Sublime Security — 3 operation(s) for hunt jobs.
Sublime Security Lists API
The Lists API from Sublime Security — 4 operation(s) for lists.
Sublime Security Live flow API
The Live flow API from Sublime Security — 1 operation(s) for live flow.
Sublime Security Mailboxes API
The Mailboxes API from Sublime Security — 1 operation(s) for mailboxes.
Sublime Security Message Groups API
The Message Groups API from Sublime Security — 17 operation(s) for message groups.
Sublime Security Messages API
The Messages API from Sublime Security — 19 operation(s) for messages.
Sublime Security Organizations API

MCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVEREvent Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

ASYNCAPISecurity Posture 3
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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of Sublime Security, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
