The slop API.

One URL in. JSON out. No key needed.

Make a request

GET https://isthisaslop.site/api?url=https%3A%2F%2Fexample.com%2F

curl --get 'https://isthisaslop.site/api' \
  --data-urlencode 'url=https://example.com/about'

Use a full https:// or http:// URL. URL-encode the value, especially links with their own query strings.

POST works too, with JSON or a form-encoded url field:

curl 'https://isthisaslop.site/api' \
  -H 'Content-Type: application/json' \
  -d '{"url":"https://example.com/about"}'

The response

Illustrative excerpt; real responses also include category scores, matched evidence, coverage and timestamps.

Limits

• 12 requests per 10 minutes per client IP, shared with the website form. Cached and invalid requests count. IPv6 addresses share a /64 quota.
• 20 fresh scans per target hostname per 10 minutes. Four scans can run at once, with a service-wide budget of 100 fresh scans per 10 minutes.
• Responses include X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset (Unix time). A 429 includes Retry-After in seconds.
• Results are cached for 15 minutes. Allow up to 50 seconds for a fresh request.

What gets scanned

Up to 20 page attempts, including failures, within 42 seconds. Only direct links on the same hostname and scheme are sampled; no recursive discovery. Queries, downloads, login and action links are skipped. Each sampled page has its own score.

The overall score and category bars use the strongest scored page. crawl.scoring_page · crawl.pages

Only public HTML over standard HTTP(S) ports. No credentials, form submissions or private-network access. Scanned PHP is read as a remote response, never included or executed by our PHP application.

Errors

{"error":"Too many scans. Please wait and try again.","retry_after":120}

GET URLs may appear in infrastructure logs. Use POST for links with sensitive query strings. This endpoint is intended for server-to-server use; browser cross-origin access is not enabled.

Scanning isthisaslop.site returns status: "self_detected", score: null and an Easter egg instead of a measured score.
