Frequently asked
- How often is the data updated?
- We check the source daily and publish a new import whenever the published archive changes and validates. The source itself publishes on no fixed schedule. Between February and September 2026 it published 16 times, with gaps from two days to seven weeks. /v1/source-status always reports exactly which publication you are reading.
- What counts as a request?
- One HTTP request to a /v1 endpoint. Requests that fail because of an error on our side are not counted. Every response carries X-Quota-Remaining.
- What happens when I hit my quota?
- Requests return 429 with monthly_quota_exceeded and the plan that would have served them. We warn by email at 80% and 90% first. Quotas reset on the first of the month.
- Can I cancel?
- Yes, at any time. Your plan stays active until the end of the period you have paid for.
- Can you provide an SLA?
- Through a custom Enterprise agreement.
