Developer-First API Telemetry

Developer-First API Monitoring For Modern REST & Microservices

Monitor API endpoints with granular request controls, OAuth/Bearer tokens, JSON body assertions, multi-step transaction chains, and bank-grade mTLS verification.

Custom Headers & Authentication

Inject custom HTTP headers, Bearer tokens, Basic Auth credentials, API keys, or custom user-agents to simulate authentic client requests.

Multi-Step Synthetic User Journeys

Chain sequential API calls together. Extract dynamic JSON variables (such as auth tokens or resource IDs) from Step 1 and pass them to downstream steps.

Cryptographic mTLS Handshakes

Authenticate against zero-trust APIs using client certificates and custom enterprise Root CAs with zero private key leakage.

Sub-Second Incident Detection

Checks execute every 10 to 30 seconds with instant multi-region quorum consensus to prevent noisy false positives.
