Common questions

What counts as one request?
Each call to any API endpoint uses one credit. Doesn't matter which endpoint — district lookup, school search, or boundary fetch all cost one credit each.
What happens when I hit 500 requests?
On the free tier, requests over 500 return a 402 error until your quota resets on the 1st of the month. On paid tiers, requests over your monthly limit return a 402 until the next billing cycle. Upgrade anytime from your dashboard.
Is this really free federal data?
Yes. All data is sourced from NCES Common Core of Data, NCES EDGE geocodes, and Census TIGER boundary polygons — all public domain federal datasets. The value we add is normalization, geospatial lookup, and a clean developer experience.
When is data updated?
NCES publishes updated CCD data each December. We update our database within 30 days of each release. The current dataset is 2024-25.
Do you have an SLA?
The Growth plan includes a 99.9% uptime SLA. All tiers run on AWS Lambda + API Gateway with Cloudflare in front — the same infrastructure used by applications serving millions of requests.
