What drives the score.
The 8.0 score rewards a low-cost, detailed IP API and daily free access. The result remains an IP lookup, so it cannot by itself connect a repeat visitor across changing addresses. These six factors show the documented evidence and the questions behind the full 38-criterion rubric.
| Detection coverage 30 percent of rubric | The stable v3 API returns VPN, proxy, hosting and Tor detections with risk and confidence information. |
|---|---|
| False-positive discipline 18 percent of rubric | Confidence and detection-history fields aid review, but the IP result still needs user context for a high-friction action. |
| Integration 16 percent of rubric | IP lookup API |
| Freshness 14 percent of rubric | The v3 documentation exposes risk, confidence, detection history and last-seen information. |
| Verdict depth 12 percent of rubric | Typed IP classifications and risk information, rather than a persistent visitor identity. |
| Pricing and access 8 percent of rubric | 1,000 queries per day for registered users; Paid plans from 4.99 US dollars per month |

FAQ about proxycheck.io.
Does the API only return a boolean?
No. The v3 documentation describes multiple detection types, risk information and history fields.
Can it link a user across rotating VPN addresses?
It checks an IP. A separate device or account identifier is needed to link a returning user across exits.
When is it a better fit than a larger platform?
When your application already makes the account decision and only needs a detailed, affordable IP lookup.
