Cost Monitoring API & Webhooks
REST API for line items, rollups, and anomalies. Webhooks push anomaly alerts to your systems. Integrate cloud and AI cost data into dashboards, ticketing, or automation.
StackSpend exposes a REST API for line items, daily rollups, and anomaly alerts. Configure webhooks to receive anomaly.created events via HTTP POST — route spend alerts to PagerDuty, internal dashboards, or Slack bots. API keys with scoped permissions. Postman collection included.
The problem
Cost data lives inside yet another dashboard. Your team already uses internal tools, ticketing systems, and operational dashboards. Manually copying numbers is slow and error-prone.
Anomaly alerts arrive in Slack or email, but your on-call flow lives in PagerDuty. Your CFO wants cost data in the board deck. Your eng team wants spend in Linear. Nothing talks to each other.
Building custom integrations means scraping screens or waiting for CSVs. You need programmatic access — pull when you need it, push when something spikes.
The solution
StackSpend REST API provides line items, daily rollups, and anomaly alerts. Create an API key in Settings. Use scoped permissions (e.g. read-only for reporting). Download the Postman collection to get started.
Webhooks deliver anomaly.created events to your endpoint via HTTP POST. Configure a URL and secret in Settings → Webhooks. When we detect a spend spike, we POST the payload. You route it to PagerDuty, a Slack bot, or your internal dashboard.
Combine API polling for dashboards and reports with webhooks for real-time anomaly alerts. No more manual aggregation or delayed discovery.
