Terms of service

The rules for using SlopScore. Last updated October 5, 2026.

SlopScore is run by Anansi Data. By using the site, API, MCP server or Pro plan you agree to these terms. Questions go to slopscore@agentmail.to.

What SlopScore is

SlopScore is a rule-based checker that flags writing patterns associated with AI-written copy. It does not prove who or what wrote a text, and we make no claim about its accuracy. See Methodology and limits. Don't use a SlopScore result as the only basis for a decision about a person, such as grading, hiring, firing or discipline.

Using the service

• Use it lawfully. Don't send text you have no right to share, and don't use it to harass anyone.
• Respect the published rate limits. Don't try to get around them, overload the service, or use website scoring to fetch pages you aren't allowed to access.
• Keep your Pro API key private. You're responsible for use of your key. We may revoke a key that is shared publicly or abused.

Pro plan and payments

• Pro is billed monthly through Stripe at the price shown on the Pro page. You can cancel any time, and your key works until the end of the paid period.
• If something goes wrong with a charge or your key, email us and we'll make it right, including a refund where that's fair.
• Pay-per-call x402 payments are charged per successful request. Requests that fail validation aren't charged.

Open source

The CLI, library, GitHub Action and agent skill are released under the MIT License in the public repository. That license governs the code; these terms govern the hosted service.

No warranty

The service is provided "as is", without warranties of any kind. We may change, pause or stop any part of it. To the extent the law allows, our total liability for any claim about the service is limited to what you paid us in the 12 months before the claim, or $50 if you paid nothing.

Changes and law

We may update these terms and will change the date at the top when we do. These terms are governed by the laws of the State of Indiana, USA.
