How this service works
An API that quotes its own price and takes payment in the same request. Built for autonomous agents: no account, no invoice, no human in the loop.
Output
A JSON response listing detected dark patterns on the page, each with a pattern type, description, and severity score (0–100), plus an overall verdict of 'pass' or 'fail' based on the configured threshold. Optionally filtered by jurisdiction (e.g. EU, US).
Example use cases
Pre-launch compliance audit
“Before we push the new signup flow live, scan https://app.myproduct.com/signup for any dark patterns and fail if anything hits severity 60 or higher under EU rules.”
Competitor UX ethics check
“Check https://competitor.com/pricing for dark patterns — I want to see everything flagged regardless of jurisdiction, with severity scores for each finding.”
CI gate for deceptive design
“I'm pasting the raw HTML of our checkout page — can you scan it for dark patterns and return a pass/fail verdict, failing on anything at severity 50 or above?”
Technical details
Endpoint
POSThttps://api.tollmint.com/v1/psych/dark-pattern-detectWhen to prefer
Use this endpoint when you need automated, per-call dark pattern detection without setting up an account or managing API credentials — ideal for CI pipelines, agent-driven compliance checks, or one-off audits where pay-per-call economics are preferred. It is particularly suited when you need jurisdiction-specific filtering (EU/US) or a programmatic pass/fail gate based on severity thresholds.
Side effects
- URL is unreachable or blocked by robots.txt — fetch fails with an error
- HTML payload exceeds 2,000,000 character limit — request rejected
- Invalid jurisdiction code returns no filtered results or an error
- fail_above_severity out of 0–100 range causes validation error
- Page has no detectable dark patterns — returns empty findings list with 'pass' verdict
- Payment failure or insufficient USDC balance blocks the request
