Leanplum
Leanplum is a mobile marketing and multichannel customer engagement platform offering push notifications, in-app and email messaging, behavioral event tracking and analytics, A/B testing, and remotely configurable content variables. Leanplum was acquired by CleverTap in 2022 and now operates as "Leanplum by CleverTap"; the brand and its documented REST API remain active while customers are migrated onto the CleverTap platform (CleverTap has wrapped its own methods behind the Leanplum API surface to smooth that transition). All API requests are made to https://api.leanplum.com/api and authenticated with an appId plus an operation-specific clientKey (production, development, data export, or content read-only).
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles Leanplum the way a machine reads it — 32 machine-readable artifacts across 2 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 — Leanplum scores 55.5/100 (strong), with a separate agent-readiness read of 30/100 (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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Leanplum
Each block below is one kind of artifact we hold for Leanplum. 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 14
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.
Leanplum A/B Tests API
The A/B Tests API from Leanplum — 3 operation(s) for a/b tests.
Leanplum Content & Variables API
The Content & Variables API from Leanplum — 3 operation(s) for content & variables.
Leanplum Data Export API
The Data Export API from Leanplum — 5 operation(s) for data export.
Leanplum Events & Tracking API
The Events & Tracking API from Leanplum — 7 operation(s) for events & tracking.
Leanplum Messaging API
The Messaging API from Leanplum — 3 operation(s) for messaging.
Leanplum Postbacks & Batch API
The Postbacks & Batch API from Leanplum — 2 operation(s) for postbacks & batch.
Leanplum User & Device Attributes API
The User & Device Attributes API from Leanplum — 4 operation(s) for user & device attributes.
Leanplum Campaigns API
The Campaigns API from Leanplum — 1 operation(s) for campaigns.
Leanplum Export Data API
The Export Data API from Leanplum — 8 operation(s) for export data.
Leanplum Files and Variables API
The Files and Variables API from Leanplum — 5 operation(s) for files and variables.
Leanplum Import Data API
The Import Data API from Leanplum — 2 operation(s) for import data.
Leanplum Messages API
The Messages API from Leanplum — 7 operation(s) for messages.
Leanplum User Behavior API
The User Behavior API from Leanplum — 9 operation(s) for user behavior.
Leanplum User Information API
The User Information API from Leanplum — 7 operation(s) for user information.

Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.
Leanplum Rate Limits
RATE LIMITSFinOps 1
Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.
Cost, billing, and metering signals for API financial operations.
Leanplum Finops
FINOPSEvent 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.
AsyncAPI definitions for this provider's event-driven and streaming APIs.
Leanplum Postbacks Webhooks
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 Leanplum, 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.
