What's the difference between the three consortium check surfaces?

Last updated: July 8, 2026

Baselayer allows for 3 different routes to check application data against its fraud consortium:

When to use

Cost / latency

Inline (in POST /searches)

Already running a full KYB.

No extra API call, already included as part of watchlist_hits.

Ad-hoc (POST /consortium/searches)

Quick screen with raw identifiers, no full KYB.

Synchronous, single round-trip.

Batch (POST /consortium/searches/batches)

Portfolio sweeps, monitoring, many businesses at once.

Async; results in JSONL via signed URL.
