# OrbitRail documentation

Build reliable event workflows with OrbitRail Events and verify every payload with OrbitRail Verify.

## Choose your product

#### [OrbitRail Events](/events/overview)

    Publish events through one HTTP endpoint, retry failed deliveries for 24
    hours, and replay retained payloads for seven days.

#### [OrbitRail Verify](/verify/quickstart)

    Validate signed payloads in Node.js 18 or newer with a typed client that
    resolves each check to a boolean.

## One reliability contract

OrbitRail Events authenticates API requests with `X-OrbitRail-Key`. The Verify
SDK uses your OrbitRail API key and batches verification work through the
`batchSize` option, which defaults to **50** and accepts values up to 500.

> **Note:**
  This documentation describes OrbitRail Events 1.0 and OrbitRail Verify 1.0.
  Product changes should update this site and every connected customer-facing
  surface through reviewable pull requests.
