FAQ
API Protection pricing questions
- What counts as an API request?
- Every request to your protected endpoints that ArxLayer inspects counts toward your monthly allowance, including requests it blocks for schema, auth, or abuse violations.
- How does schema discovery work?
- You import an OpenAPI or GraphQL definition, or ArxLayer learns your endpoints from observed traffic, then validates requests against the expected schema and flags drift.
- What happens if I exceed my request limit?
- You can upgrade a tier or add request bundles. We alert you before you reach your limit and never silently drop enforcement.
- Do you offer annual billing?
- Yes. Annual billing is available, and Enterprise plans are tailored to your endpoint count, request volume, SLA, and compliance needs.
