If the response status is "queued" or "running", poll GET https://api.doitong.com/v1/requests/REQUEST_ID?wait=20 until it is "succeeded"; the files are in outputs[].url. POST https://api.doitong.com/v1/quote/workflow-utilities/impulse-response with the same body returns the exact price before the run.
Up to $1.80 per run charged by actual usage, the rest is refunded Run it on this page

About Workflow Utilities Impulse Response
Convolves an audio file with an impulse response WAV to add reverb or another room or effect profile. `dry_level` and `wet_level` (0 to 1) set the mix. Loudness targets are adjustable through `loudness_i`, `loudness_lra` and `loudness_tp`. Output bitrate can be 128k, 192k, 256k or 320k.
