The Tracker lens-owned verify surface: a per-node verdict over the
normalized DDG Tracker Radar / IAB TCF / Disconnect.me corpus, with an
optional signed TunnelMind Receipt v1.0. This is the single-lens ground
truth the fused `POST /v1/verify` cites for its tracker block.
Use this tool when:
- You need to know whether a domain is tracking/surveillance infrastructure
and which entity operates it, without the full cross-lens fusion.
- You want a signed, offline-verifiable receipt for that single-lens answer.
Inputs:
- `node` (path, required): a domain (e.g. `doubleclick.net`) or an entity
slug (e.g. `google`). IPs and ASNs are not indexable by this lens.
- `receipt` (query, optional): `true` attaches a Receipt v1.0 envelope.
Returns:
- `tracking`: true (in the tracker corpus), false (queried, absent), or
null (not answerable — ip/asn node or backend unavailable; see `reason`).
- `tracker`: the lens record — domain {category, prevalence, score 0-100}
plus operating entity {slug, name, parent_company, industry, sources},
or entity + top_domains when queried by slug.
- `checked_at`: ISO 8601 timestamp of the corpus read.
- `receipt`: TunnelMind Receipt v1.0 (Ed25519, JCS) when requested.
Cost:
- Counts as one request against the daily rate limit.
Latency:
- Typical: <100ms (one or two D1 reads at the edge).
