One GET returns the tracked AI-regulation records for a jurisdiction, each with its status, its dates, and the official .gov URL behind it. Here is the whole loop: find the slug, page through the records, handle the errors, and know exactly which caps your tier is under.
Published · AI Law Tracker Editorial Team
Every read endpoint works with no credentials at all. Anonymous callers are limited to 20 requests/minute and 100 requests/day per IP, capped at 5 records per page, and receive a trimmed field envelope. That is enough to evaluate the data and not much more.
A free key — self-serve, no card — raises you to 60 requests/minute and 300 requests/day (9,000 a month), returns the complete record (summary, source, dates, in_force) and allows 25 records per page. Send it in either header form:
# Preferred
curl -s "https://ai-law-tracker.com/api/v1/health" -H "X-API-Key: alt_free_your_key_here"
# Equivalent
curl -s "https://ai-law-tracker.com/api/v1/health" -H "Authorization: Bearer alt_free_your_key_here"curl -X POST "https://ai-law-tracker.com/api/v1/keys" \
-H "Content-Type: application/json" \
-d '{"email":"you@company.com"}'The jurisdiction filter takes an exact slug, not a display name. GET /v1/states lists the US state jurisdictions with their record counts; GET /v1/jurisdictions covers everything including us-federal, eu and country slugs.

}GET /v1/laws accepts scope, jurisdiction, status (case-insensitive substring), in_force, updated_since, q, sort (updated_at | record_date | title), order, limit and offset. Filters and sorting are honoured at every tier — only page size and pagination depth are tier-capped.

}updated_at moves only on a real content diff; checked_at moves every time the source was successfully re-checked, even when nothing changed. Use updated_at for “what changed”, checked_at for “how fresh is this”.Page with limit and offset, and stop on meta.total — never on an assumption about page size. If you ask for more than your tier allows, the API does not error: it clamps the value, returns the smaller page, and tells you it did so in meta.gated. Read the echoed meta.limit rather than the one you sent.

}Every failure uses one envelope, so a single handler covers all of them:
scope, an unparseable updated_since, or a missing q on /v1/search. The message names the offending parameter.Retry-After and error.retry_after both tell you how long to wait. Back off; do not retry tightly./v1/changes, /v1/feed, /v1/laws/{id}/history). The body names required_tier, so you can surface a precise message instead of a generic denial.meta.gated naming what was clamped and meta.upgrade explaining why.{

"error": {
"code": "rate_limited",
"message": "…",

}
}When you want “everything about deepfakes in Texas” rather than “everything in Texas”, use GET /v1/search. It takes the same parameters as /v1/laws plus a required q, and defaults to newest-first by record_date.

Yes for this workload — free as in no card, not free as in no signup. A key is required on every data endpoint, and the free one is self-serve: 60 req/min, 300 req/day, 9,000 req/month, the full record envelope and 25-record pages. Paid plans exist for production volume, the change feed, history and webhooks.
Your tier clamped it. Free is capped at 25 records per page. The response is still a 200 — check meta.limit for what was applied and meta.gated for the list of clamped parameters. Paid tiers allow the full 100.
By default it counts AI-specific records, which is echoed back as meta.ai_scope so the number is never ambiguous. It is the total matching your filters, not the size of the page — page with limit and offset until offset reaches total.
