SD1 (spec 14, decision 0006): IPQualityScore first, then the FTC Do Not Call complaint list, for outside US callers who aren't in anyone's contacts. Information only, off by default; credits running out pause IPQualityScore until its credit usage API says they're back.

# 0006 — Spam check: IPQualityScore and the FTC complaint list
|
|
|
|
Owner, 2026-10-27: show what's known about an outside caller who isn't in anyone's contacts
|
|
(14). The callers are in the US, so the providers are US ones: **IPQualityScore** (a live
|
|
lookup with a fraud score, spammer and recent-abuse flags, line type and carrier; free plan of
|
|
1,000 lookups a month) and the **FTC Do Not Call complaint data** (free, synced daily into a local
|
|
table through api.ftc.gov, so a check sends nothing out). IPQualityScore answers first when set
|
|
up; the FTC list answers when it isn't or can't. Rejected: OpenSpam (Spanish numbers;
|
|
kept for later), Hiya and Telnyx Number Reputation (contract only, or only for your own numbers),
|
|
Truecaller (no open API), CallerAPI, Nomorobo, Trestle and YouMail (no free plan, prices on
|
|
request or per query only). No package is added: both are plain HTTPS with `fetch`. IPQualityScore
|
|
is closed-source, but it's an optional outside service the admin turns on, like an SMTP server,
|
|
not a component we ship. It sends the caller's number out of the server, so it is off by default
|
|
and asks the admin to confirm (14 §8).
