Plans and limits
Endpoint access, minute rate limits, and quotas.
| Plan | Price | Minute rate limit | Quota | Included routes |
|---|---|---|---|---|
| Free | $0/mo | 30/min | 100/day | /search, /coverage, /snapshot, /valuation |
| Starter | $29/mo | 60/min | 10,000/month | All current v2 routes |
| Builder | $99/mo | 300/min | 75,000/month | All current v2 routes |
Free route set
Free is intentionally limited to the proof workflow:
- Discover a symbol with
/v2/search. - Confirm support with
/v2/coverage. - Pull broad context with
/v2/snapshot. - Check valuation with
/v2/valuation.
All other routes return PLAN_UPGRADE_REQUIRED on Free.
Subscription changes
When your Clerk Billing subscription changes, noxstock syncs your existing Unkey API keys to the current plan:
- upgrade/update/active → existing keys receive the new plan metadata and rate limit
- cancel at period end → keys stay on the paid plan until the subscription ends
- ended/past due → existing keys are downgraded to Free
- user deletion → keys are revoked
