I do not perceive transactional relationships as a tragedy. It's the best feedback loop there is.
You achieve the goals that are aligned with the business - business pays you.
I've been a contractor for 10 years and never took a dollar unless the goal is achieved. Ended up getting full-time position as a head of engineering hefty compensation by one of my clients.
no training on API as well. I integrated it with Telegram over a year ago. For convenience rather than for cost savings. Been paying $2 per month on average ever since. And "No training on your data" is included.
