Question 1

What is LayerCall?

Accepted Answer

LayerCall is a fraud and trust-signals API. Send an IP, email, phone, or domain — or a whole signup — and get back a 0–100 risk score and an allow, review, or block verdict in a single API call.

Question 2

Is there a free tier?

Accepted Answer

Yes. Every account gets 1,000 lookups per month free, with no credit card required. Paid plans start at $49/month for 20,000 lookups with published overage rates.

Question 3

What can I check?

Accepted Answer

IP reputation (VPN, proxy, Tor, datacenter, geolocation, ASN), email validity and disposable/risky detection, phone validity and risk, and domain age, MX, and throwaway-domain signals — individually or combined into one unified signup score.

Question 4

How fast is it?

Accepted Answer

Cached lookups return in under 0.003 seconds; first-time lookups typically complete in well under a second. Cached and test-mode lookups never count toward your quota or bill.

Question 5

Do you store personal data?

Accepted Answer

The reputation network stores only a SHA-256 hash of observed values, never raw IPs or emails. There is no personal data to leak in a breach.

Question 6

How is LayerCall different from 1Lookup or IPQualityScore?

Accepted Answer

Same instant, self-serve, public-pricing model — at a lower entry price, with a clear card-free free tier, one-click Google sign-in, and separate live and test API keys. See the comparison pages for a side-by-side.
