Buyer's guide

AI law API comparison: how to choose

If you're integrating AI-regulation data, the API you pick decides how much scraping and reconciliation you own forever. This is a vendor-neutral checklist of what to demand — with our concrete answer on each, so you can judge us against it too.

1

Coverage in one schema

AI rules are fragmenting across US states, the federal layer, the EU AI Act, and other countries. Stitching several US-only feeds together is where integrations rot.

AI Law Tracker: 51 US jurisdictions + federal, the EU, and 11 more countries — one record shape (`scope`, `jurisdiction`, `status`, `official_url`) across all of them.
2

Primary-source provenance

For a legal use case, a bill number with no link to the statute is a liability. Every record needs a verifiable government source.

AI Law Tracker: Each record carries an `official_url` to the primary .gov source and a verification date. Records with no primary source are excluded from the indexable dataset.
3

Machine-readable change feed

You need to know what changed since your last sync — not re-diff the whole dataset on every run.

AI Law Tracker: Pollable `/v1/changes` + `/v1/feed` with a cursor and per-field diffs (e.g. status In committee → Passed House).
4

Push notifications

Polling is fine to start; at scale you want a signed push when a law you track moves.

AI Law Tracker: HMAC-SHA256-signed webhooks on `law.created` / `law.updated`, with retry + dead-letter handling.
5

Self-serve access & clear pricing

If evaluating the data means booking a sales call, prototyping stalls.

AI Law Tracker: Free key by email in seconds; published tier ladder with paid API from $0/mo. No card to start.
6

Reuse rights

Building a product on top of the data? The license decides whether you legally can.

AI Law Tracker: Data is CC BY 4.0 — commercial reuse allowed with attribution (attribution required on the free tier, optional on paid).
7

Honest about limits

A data source that never says "verify against the source" is over-promising on a YMYL topic.

AI Law Tracker: Every response carries a "not legal advice — verify against `official_url`" disclaimer. We publish what a primary source backs and nothing more.

Our API, priced to grow

The full dataset is on every tier — you pay for volume, changelog depth, and webhooks. For contrast, AI Laws by State lists API access on its Enterprise ($499/mo) plan.

FAQ

What should an AI-regulation data API include?

At minimum: broad jurisdiction coverage in one schema, a primary-source URL on every record, a machine-readable change feed, push webhooks, self-serve access with clear pricing, and reuse rights (a clear data license).

Is there an AI law API with a free tier?

Yes — the AI Law Tracker API has a free self-serve key (emailed in seconds, no card), with paid tiers from $0/mo for higher limits, a longer changelog window, and webhooks.

Which AI law APIs cover the EU and not just US states?

Many trackers are US-only. AI Law Tracker exposes US state + federal, the EU AI Act, and 11 more national regimes through one record shape. AI Laws by State, for example, publicly lists United States — 50 states.

How much does an AI regulation API cost?

AI Law Tracker: free self-serve tier, then paid API from $0/mo. By comparison, AI Laws by State lists API access on its Enterprise ($499/mo) plan — so entry price and where the API sits in the ladder vary widely.
