What's the same

POST /api/v1/usageingestion endpoint with anIdempotency-Keyheader. - Late and backdated events land in the period they happened.
- Sum, count and unique-count aggregation (UsageBox also offers max).
- Monthly rollups per subscription, and raw events kept.
- No SDK; copy-paste HTTP snippets.
Where they differ
| UsageBox | Usage Lab | |
|---|---|---|
| Handoff to your biller | Biller-agnostic: you read rollups and feed Stripe, Lago or your own code | Native push of monthly deltas to Stripe Billing Meters. Coming soon; dry-run today |
| Data model | Projects, products, plans, meters, customers, subscriptions | Meter + subscription + event |
| Hosting | GCP (Cloud Run, Firestore, Pub/Sub, per its own article) | Cloudflare Workers + D1, with a Worker middleware snippet for edge metering |
| Auth header | x-api-key | Authorization: Bearer or X-Api-Key |
| Late window | Not stated on the pages reviewed | 30 days, published |
| Maturity | Established product with OpenAPI spec and explorer | Early access; keys issued manually |
Which should you pick?
- Pick UsageBox if you bill in USD, want max aggregation or a richer catalog, or need a more mature product today.
- Pick Usage Lab if you bill in CAD, run on Cloudflare Workers, want the smallest possible model, and want Stripe push when it ships.
