SlopScore Pro

$9 a month for an API key that lets you check long documents. The browser checker stays free for everyone.

$9/mo

An API key for POST /api/check that raises the limit from 5,000 to 200,000 characters per call.
Use it from your own scripts, a docs pipeline, or the open-source CLI and GitHub Action.
Email support at slopscore@agentmail.to.

Monthly, no trial, cancel any time. Checkout is handled by Stripe. After you pay, we email your API key to the address you used at checkout within 24 hours. Key setup is manual for now, so it isn't instant.

Using the key

curl -s -X POST https://slopscore-nine.vercel.app/api/check \
  -H 'authorization: Bearer ss_your_key' -H 'content-type: application/json' \
  -d '{"text":"...your long document..."}'
