Investigate any URL

curl -X POST "$DOATHING_API/v1/explore/url-detective" \
  -H "x-api-key: $DOATHING_KEY" \
  -H "content-type: application/json" \
  -d '{"url": "https://example.com/article?utm_source=newsletter"}'

Paste a link and see where it really goes: every redirect, what it says about itself when shared, who else it loads from, and which parts of the address are only tracking you.

Fetch a URL and report its redirect chain, metadata and sharing cards, third-party hosts, tracking parameters and a health score.

Response

The result carries your remaining balance alongside it, so you can track spend without a second call.

Cost

3 credits per call, whether it is run from the site or from the API — the credential differs, the price does not. A new account starts with 20 credits.

A rejected request still costs a credit: the authorizer decrements before the tool validates. A call rejected for a missing or invalid key is free.
