API monitoring built for engineering teams
Monitor your critical APIs from multiple regions, verify failures before triggering incidents, and continuously measure availability and latency.
Built for engineering teams running critical APIs across the globe. No credit card required.
Go beyond HTTP 200
A 200 OK from an empty error page is not availability. Uptara evaluates authentic payload semantics, certificates, and end-to-end workflows.
REST APIs
GET, POST, PUT, DELETE, PATCH, and HEAD methods with customizable payloads, headers, and query parameters.
Authenticated Endpoints
Native Bearer tokens, API keys, Basic Auth, and OAuth2 authorization headers evaluated on every probe.
Multi-Step API Workflows
Chained synthetic requests passing dynamic variables like auth tokens or order IDs across sequential calls.
mTLS-Protected Services
Private microservices and banking APIs authenticated via client certificates and custom enterprise Root CAs.
Internal & Customer-Facing APIs
Granular health checks for customer-facing public gateways as well as internal backend service dependencies.
Critical Business Transactions
Verify that payment checkouts, webhook dispatches, and user onboarding pipelines succeed without silent failure.
Whether you're running a SaaS platform, fintech API, developer platform, or distributed backend, Uptara helps your team understand whether your services are truly healthy.
Why Engineers Choose Uptara Over Legacy Monitors
Designed from first principles to reduce false-positive alerts and provide actionable debugging telemetry.
Multi-Region Quorum Consensus
When a probe detects an error, probes in other regions (US-East, EU-Central, AP-South) vote immediately. Outages require quorum confirmation, completely isolating transient regional ISP routing drops.
Anti-Flapping & Confirmation Thresholds
Configure your alert threshold (1 to 5 consecutive failures). The system absorbs momentary 2-second hiccups with live dashboard confirmation states, reserving high-priority pager alerts for confirmed downtime.
Deep JSON & Latency Assertions
Assert exact HTTP status codes, evaluate JSONPath selectors against expected strings or booleans, and enforce strict p95 latency thresholds so performance degradations are caught early.
Instant Multi-Channel Escalation
Receive rich incident payloads with failure cause, response time, and edge region breakdown delivered directly to WhatsApp, Slack Block Kit, Discord, PagerDuty, or HMAC-signed webhooks.

}Frequently Asked Questions
Uptara uses a two-layer verification architecture: multi-region quorum consensus across 3 continents (US-East, EU-Central, AP-South) and configurable consecutive failure thresholds (e.g. require 2 failed probes before declaring an incident). A single temporary network packet drop will never wake up your on-call engineers.
Uptara supports GET, POST, PUT, DELETE, PATCH, and HEAD. You can configure custom request headers (Authorization, X-Api-Key, Content-Type), send JSON or plaintext bodies, assert exact HTTP status codes, test latency thresholds, and validate JSONPath response body keys.
Yes. Uptara natively supports mutual TLS. Upload your client certificate and private key (stored securely with AES-256-GCM envelope encryption via KMS) along with an optional custom Root CA. Probes establish cryptographic mTLS handshakes on every check.
Synthetic monitors chain multiple sequential HTTP requests. For example: Step 1 logs in via POST /v1/auth, extracts the bearer token from the JSON response, and automatically injects it into Step 2 (POST /v1/checkout) to verify that end-to-end commerce logic is operational.
Alerts are dispatched sub-second across WhatsApp, Slack Block Kit, Discord webhooks, PagerDuty, email, and custom signed HMAC endpoints the moment an outage reaches the quorum and confirmation threshold.
