Wellfound Application Modal API
Read a Wellfound listing's application modal: its screening questions with option ids, whether this account has already applied, and the qualification report. Read-only, and the intended step immediately before wellfound-apply. Requires an authenticated session blob from wellfound-login.
How to call it
Send one POST to api.upapi.io/wellfound-application-modal.post with your key in the X-Api-Key header and the parameters below as a JSON body. Each call spends 4 weighted units of your monthly quota. The operation times out after 30 seconds. Responses are not cached; every call runs the operation.
