Access tiers
Tools fall into three access levels — evaluate the light ones with no account at all, sign in for the rest, and unlock the AI suite on a paid plan. Each reference page states its own requirement.
Three access levels
- Free to try — callable with no credentials, metered at 0 credits, rate-limited by IP.
- Login required — any signed-in account (a
dt_live_key or JWT); charged normally. - Pro / Enterprise only — the AI suite; anonymous returns
401, a free-tier account returns403.
Free-try needs a browser origin
The anonymous path is designed for in-browser evaluation — it’s allowed when the request carries an allowedOrigin/Referer. A raw server-side call with no key may get 401 even for a free-try tool, so for programmatic use send a key. See Authentication.Free to try
These run without a key (0 credits, IP-rate-limited):

A paid plan for AI paths
PDF→Markdown’s AI paths (llm_cleanup=true or engine=vision) are a paid feature — a free-tier account requesting them gets 403, while the standard path works on any paid plan.Pro / Enterprise only
The dedicated AI tools require a Pro or Enterprise plan:
The plan gate runs before metering — anonymous callers get 401, authenticated free-tier accounts get 403 (“this feature requires ENTERPRISE/PRO tier”). Upgrade in your dashboard to enable them.
