Conversion psychology, as an API.
Jung Fortis is an API that returns a conversion-psychology analysis of a web page. Send one URL and it returns a structured report: Cialdini's six levers of influence, Fogg's motivation–ability–prompt model, and a prioritised list of fixes that each carry the evidence they rest on and the result that would prove them wrong.
One-time top-up. Your API key is issued when the payment clears.
What the analysis contains
Cialdini's six levers
Reciprocity, commitment and consistency, social proof, authority, liking and scarcity — each marked present, absent or misused, each carrying a verbatim quote from the page.
The binding constraint
Fogg's behaviour model applied: motivation, ability and prompt are diagnosed separately, and the report names which one is actually stopping the behaviour.
Prioritised, falsifiable fixes
Every fix states what to change, what to measure and the result that would prove it wrong. Observed facts and the reading placed on them are labelled separately.
Pricing
One analysis costs one credit. Credits are bought in a single top-up of $100 or more — you choose the amount. There is no subscription, no recurring billing and nothing renews automatically.
| Top-up | Credits | Analyses |
|---|---|---|
| $100 — the minimum | 100 | 100 |
| Any amount above $100 | That many | That many |
Credits are closed-loop: they pay for analyses on this service. They are not transferable, cannot be redeemed for cash, and do not expire. A refund or chargeback revokes the API keys on that purchase — see the refund policy.
How buying works
Top up
Pay once, in an amount you choose, from $100. The payment is a one-time purchase, not a subscription.
Your key is issued
When the payment clears, the service is notified and an API key is issued to the email on the payment. It is shown on the page you land on after checkout. You can retrieve it again from the keys page.
Each analysis debits one credit
Send a URL with your key. One analysis debits one credit. Credits are only debited when an analysis succeeds — if the page cannot be fetched, or the report fails its own output contract, you get an error and no credit is used.
What it does — and what it does not do
Does: analyses the page source you submit — copy, headings, structure, forms, links, metadata — against the six levers and the behaviour model, and returns the report as JSON. Reports remain retrievable later by their id.
Does not: see rendered layout, images, video, motion, or anything behind a login. It analyses the one URL submitted and fetches nothing else, and every report lists what it could not assess.
Text and markup only. The service generates no images, audio or video.
