Jeeng
Jeeng (formerly PowerInbox, acquired by OpenWeb in 2022 and now marketed as OpenWeb Email Monetization) is a multichannel monetization and audience-engagement platform for digital publishers. It helps publishers grow first-party, opt-in audiences and generate advertising revenue across email newsletters, websites, push notifications, and newsreader apps, reaching more than 150M opt-in subscribers. Its products — AdFill, AdServe, AdMarket, and Renderer — fill vacant ad inventory with monetized content, extend direct ad campaigns into email through existing ad servers, connect advertisers to opt-in audiences, and streamline Google Ad Manager ad-ops workflows. Publisher integration is handled through merge tags, per-newsletter ad tags, and cs_email tracking parameters plus direct Google Ad Manager integration; campaigns and reporting are managed through the portal at manage.jeeng.com. Jeeng also publishes partner Reporting & Management APIs at developers.jeeng.com — an advertiser API for campaign line and creative management plus campaign/performance reporting, and a publisher API for container, placement and publisher performance reporting — served from powerinbox.azure-api.net behind Microsoft Entra ID OAuth 2.0 client-credentials tokens. API access is not self-serve: an account manager provisions the client id and client secret.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Jeeng the way a machine reads it — 12 machine-readable artifacts across 6 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 — Jeeng scores 36.1/100 (thin), with a separate agent-readiness read of 35/100 (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 Jeeng
Each block below is one kind of artifact we hold for Jeeng. 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 3
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.
Jeeng Management API
The Management API from Jeeng — 3 operation(s) for management.
Jeeng Reporting API
The Reporting API from Jeeng — 6 operation(s) for reporting.
Jeeng Revenuestripe.onmicrosoft.com API
The Revenuestripe.onmicrosoft.com API from Jeeng — 1 operation(s) for revenuestripe.onmicrosoft.com.
Open Collections 3
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.
Open, tool-agnostic API collections (OpenAPI-derived and Bruno).

OPEN COLLECTIONMCP 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.

Jeeng MCP Server
MCP SERVERPricing 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.
Jeeng Plans Pricing
PLANSRate 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.
Jeeng Rate Limits
RATE LIMITSSecurity 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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.

This is an independent, third-party profile of Jeeng, 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.
