description: '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.'

  description: Advertiser-side campaign management and reporting for the Jeeng / OpenWeb Email Monetization platform. Update
    campaign lines (daily spend goal and CPC/CPM/CPA pricing), transition campaign line and creative status between running,
    paused and archived, and pull campaign and campaign-line reports at daily or hourly grain using OData V4 $filter queries.
    A flexible advertiser performance report returns a 303 redirect to a CSV download for a caller-specified set of fields,
    filters and groupings over a date range of up to 32 days. Requires an OAuth 2.0 client-credentials bearer token from the
    Microsoft Entra tenant, requested with the partners scope; credentials are provisioned by an account manager.

  description: OAuth 2.0 client-credentials token endpoint for the Jeeng / OpenWeb Email Monetization partner APIs, published
    by Jeeng as its own OpenAPI definition. Tokens are issued by the Microsoft Entra ID (Azure AD) tenant revenuestripe.onmicrosoft.com
    and must be requested with the scope api://revenuestripe.onmicrosoft.com/partners/.default, which grants access to every
    partner endpoint. The resulting access_token is sent as a bearer token to the advertiser and publisher APIs.

  note: Round 1 recorded "Jeeng publishes no public developer API". That was wrong. STEP 0b contract discovery found a live
    ReadMe developer hub at developers.jeeng.com (readme-subdomain "jeeng") publishing three OpenAPI 3.1.0 definitions and
    ten operations against https://powerinbox.azure-api.net/, plus a served llms.txt and a gated MCP endpoint.
