Revenue Share FAQ

Q: How is revenue share calculated? A: Every time a user makes an estimate through your API key, we track the savings they realized vs. picking the most expensive model. You earn a percentage of the estimated value routed.

Q: When do I get paid? A: Monthly, via Stripe, when your balance exceeds the minimum payout threshold.

Q: Does transcription count too? A: Yes. Transcription revenue counts toward your tier and your rev-share at the same rates.

Q: What if I don't hit 10K estimates? A: You earn at the Loom Partner rate (23%) from day one. There's no minimum to start earning.
