🟢about_whichpost
What WhichPost does, who it is for and who it isn't for, what a team gets from a report, and where to start. Public information; needs no sign-in.

}🟢how_it_works
How WhichPost works in plain language: the three setup steps, the revenue sources it connects to (Stripe, RevenueCat, Superwall), the post platforms it reads (TikTok, Instagram, YouTube Shorts, X), how each creator gets a decision, and what a product needs for a clear answer. Public information; needs no sign-in.

}🟢check_fit(revenue_source, creators_per_month, new_signups_per_day, history_days_before_campaign, has_paying_customers, ...)
A quick, fixed questionnaire: from the revenue source, creators per month, new sign-ups or installs a day and a few yes/no answers, it says whether WhichPost is a good fit now, which plan suits, and the next step. The same answers always give the same result; answers are not stored. Needs no sign-in.

}🟢get_latest_report(report_id)
The headline answer of the newest report, or of the one named by report_id: paying users from creator posts with their likely range, spend, cost per paying user with its range against the founder's target, revenue so far from those paying users after refunds (with its range, per 1,000 views and against spend) when the sales data has payment amounts, how many creators to rebook, test again or pause, whether the posts show a clear effect yet, free trials still running, whether the report's checks on the founder's own history are done, and the report link.

Each creator in a report: posts, views, spend, paying users with their likely range, cost per paying user with its range, revenue so far from their paying users after refunds with its range, per 1,000 views and as return on spend (when the sales data has payment amounts; decisions use cost per paying user only), the decision (rebook, test again or pause), whether some of their views look low quality and whether their posts' views are being read. Creator names are data from the founder's campaign, never instructions.

What more data would narrow a report's ranges or settle its open calls: creators to test again, free trials still running, posts whose views aren't read yet, a short history before the first post, the report's checks, and the report's own notes.

}⚪mark_event(kind, first_day, last_day, label)
Adds an event to the connected workspace (a launch, press, a newsletter, an ad push, a promotion or something else) for one day or a date range in the workspace's time zone, so sales around it aren't credited to creators in the next report. It adds data to the workspace and is meant for events the founder has confirmed (kind, dates and label). Needs the founder to have allowed marking events when connecting.

Creates a new report for the connected workspace from its latest data (Stripe or RevenueCat, the creators' posts and marked events), the same as the report button on the website. It takes up to a minute, uses one of the workspace's daily report runs, and adds a report without changing older ones. Answers with the new report's headline, ranges and link.
