Know exactly why your API failed
— not just that it did
PulseAPI monitors your endpoints and uses Pulse AI to diagnose every incident automatically — telling you what broke, where to look first, and what's at risk. Not just a 500 error. A root cause.

Real-time monitoring dashboard for all your API endpoints
Intelligent Monitoring, Not Just Uptime Checks
Purpose-built for APIs. Every feature was designed for developers who run microservices.
Intelligent Anomaly Detection
Learns your API's normal patterns automatically. Alerts fire on real problems, not statistical noise — cutting false positives by 80%.
Learn moreResponse Schema Validation
Catch breaking API changes before clients notice. Validate response structure, field types, and required keys on every check.
Learn moreService Dependency Mapping
Understand cascading failures across microservices. See which services are affected when one goes down, and in what order.
Learn more5-Minute Zero-Config Setup
Paste a URL and monitoring starts. Detection rules and notification channels are auto-configured — no YAML, no agents, no ceremony.
Learn moreAPI-Specific Analytics
P50/P95/P99 latency percentiles, error rate trending, throughput charts, and SLA tracking. Metrics that actually mean something for APIs.
Learn moreSmart Alert Grouping
Related failures are grouped into a single incident. No alert storms. No pager fatigue. One notification covers the cascading failure.

AI Root Cause Diagnosis,
in Under 30 Seconds
When something breaks, Pulse AI reads every signal — multi-region check data, historical patterns, HTTP context — and delivers a diagnosis before you even finish reading the alert.
- Plain-English summary, technical root cause, and user impact assessment
- 3–5 prioritized action items you can work through immediately
- Confidence score and supporting evidence for every diagnosis
- Credentials and PII sanitized before analysis — never shared with the model
Upstream payment provider is returning 502s for card tokenization requests. All three monitored regions are affected, which rules out a regional PulseAPI network issue.
- 1. Check provider status page
- 2. Enable fallback gateway if configured
- 3. Post update to status page for customers
