What’s new in Sealium

Usage accounting for batch jobs, fairer billing on engine outages, and stronger webhook verification.

• NewBatch validation now counts each submitted document against your monthly usage, so batch and single calls are metered consistently.
• NewPer-tenant webhook signing secrets (slm_whsec_…) with one-click rotation — verify every delivery with the X-Sealium-Signature header.
• New“Make your first batch request” quickstart on the Batch page.
• ImprovedCalls that fail because the engine is unavailable are now automatically refunded — an outage on our side never burns your quota.
• FixedReport date filters now accept plain calendar dates (e.g. 2026-06-12) and no longer return a server error.

Self-serve spending controls and a smoother upgrade experience.

• NewUsage overage with configurable spending caps for Pro and Business — pass your quota up to a limit you control, billed per extra call.
• NewPaddle Overlay Checkout for upgrades, with EU VAT handled automatically.
• ImprovedAfter a successful payment the billing page surfaces a refresh prompt so your new plan and features appear without a full reload.

A guided first-run experience and a single place for your account.
