Plans a bulk export of any slice /us-law can filter and returns a MANIFEST: the exact row count, what it will cost against your record allowance, and one SIGNED, short-lived download URL per part (NDJSON | CSV | JSON). The bytes come from the signed part URLs; this call serves no records and charges nothing.

NOT SOLD SELF-SERVE AT ANY PRICE. Taking the whole corpus as a file is a licensing conversation, not a checkout — every self-serve plan keeps full API access to the same data and pages it instead. A below-tier caller gets 403 tier_upgrade_required naming the tier it opens at.

Part URLs carry a signed token rather than your API key, so a link can be handed to a loader without handing over your credential; every download is still metered against the key that created it.

PRODUCT SCOPE: this endpoint belongs to the US Law Platform. A key licensed only for AI Law Tracker (product: ai_law) is NOT refused here — it is served at the PUBLIC (keyless) capability level, the same few records any anonymous caller gets. The response headers say so explicitly: X-ALT-Product (what your key holds), X-ALT-Product-Surface (us_law) and X-ALT-Product-Scope (in_product | out_of_product). Your request rate and daily/monthly quota are NEVER degraded — those are metered per key wherever you call. What degrades is capability: page size, pagination depth, field envelope and the record budget.
