If you're building monitoring automation — programmatically creating monitors, managing alert contacts, integrating uptime data into dashboards, or orchestrating your monitoring setup via CI/CD pipelines — the quality of the monitoring platform's API matters as much as the monitoring itself.

UptimeRobot has a well-known API that many teams have integrated over the years. Vigilmon offers a REST API built for modern developer workflows. This article compares both APIs directly across the dimensions that matter for automation: feature depth, authentication, rate limits, webhook support, and overall developer experience.

UptimeRobot API: What It Does Well

UptimeRobot's API has been around long enough to accumulate a solid breadth of supported operations. Its v2 API covers:

  • Monitor management: Create, read, update, delete monitors; supports HTTP, keyword, ping, port, and heartbeat monitor types
  • Alert contact management: Create and list alert contacts (email, SMS, Slack, webhook, etc.)
  • Monitor groups: Organize monitors into logical groups via the API
  • Response time data: Retrieve historical response time logs per monitor
  • Statistics: Fetch uptime percentages and downtime incident logs

A basic UptimeRobot API interaction creating an HTTP monitor looks like this:

curl -X POST https://api.uptimerobot.com/v2/newMonitor \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "api_key=YOUR_API_KEY" \
  -d "format=json" \
  -d "type=1" \
  -d "url=https://example.com" \
  -d "friendly_name=My Site"

Note the application/x-www-form-urlencoded content type. UptimeRobot's API predates the current REST convention of JSON request bodies — it uses form-encoded parameters. This works, but it's non-standard and slightly awkward when building automation tooling.

Rate limits: UptimeRobot's free plan limits API calls to 10 requests per minute. Paid plans increase this, but the rate limits can create friction when bulk-creating monitors during infrastructure provisioning events.

Missing features in the API:

  • No support for multi-region consensus configuration via API
  • No webhook delivery history or retry management
  • Status page content is not manageable via API on lower tiers
  • No response body matching rules via API

Vigilmon API: The REST-First Approach

Vigilmon's API was designed for JSON from the ground up. Every endpoint accepts and returns JSON, uses standard HTTP verbs correctly, and follows REST conventions that map cleanly to modern tooling.

Authentication

Vigilmon uses standard Bearer token authentication:

curl https://api.vigilmon.online/v1/monitors \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json"

API keys are scoped and can be rotated without disrupting the monitoring itself. For CI/CD integrations where the API key needs to live in secrets management, the standard Bearer scheme integrates cleanly with tools like HashiCorp Vault, AWS Secrets Manager, and GitHub Actions secrets.

Monitor Management

Creating a monitor with the Vigilmon API:

curl -X POST https://api.vigilmon.online/v1/monitors \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Production API",
    "url": "https://api.example.com/health",
    "interval": 60,
    "regions": ["us-east", "eu-west", "ap-southeast"],
    "alertContacts": ["contact-id-1", "contact-id-2"]
  }'

JSON request bodies compose naturally with scripting and templating tools. Provisioning 50 monitors from a YAML service inventory becomes straightforward with jq:

# Bulk create monitors from a service list
cat services.json | jq -c '.[]' | while read service; do
  name=$(echo "$service" | jq -r '.name')
  url=$(echo "$service" | jq -r '.healthEndpoint')
  
  curl -X POST https://api.vigilmon.online/v1/monitors \
    -H "Authorization: Bearer $VIGILMON_API_KEY" \
    -H "Content-Type: application/json" \
    -d "{\"name\": \"$name\", \"url\": \"$url\", \"interval\": 60}"
done

Webhook Configuration and Delivery History

Webhook management is a first-class API operation in Vigilmon. You can create, update, and delete webhook endpoints programmatically:

# Create a webhook alert contact
curl -X POST https://api.vigilmon.online/v1/alert-contacts \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "type": "webhook",
    "name": "Incident Receiver",
    "url": "https://incidents.example.com/webhook",
    "headers": {
      "X-Source": "vigilmon"
    }
  }'

Critically, Vigilmon exposes webhook delivery history via the API — you can query recent delivery attempts, their status codes, response bodies, and retry history. This is essential when debugging why an incident notification didn't reach your incident management system.

# Check webhook delivery history for a specific monitor
curl https://api.vigilmon.online/v1/monitors/{monitorId}/webhook-deliveries \
  -H "Authorization: Bearer YOUR_API_KEY"

UptimeRobot's API does not expose webhook delivery history. If a webhook notification fails, you have no programmatic visibility into why.

Status Page Management

Vigilmon's status page is fully manageable via API. You can add and remove monitors from a status page, update the page name and description, and retrieve the current public status — all programmatically.

This matters for teams that provision monitoring and status pages as part of their infrastructure-as-code workflow. When a new service is deployed, your CI/CD pipeline can create the monitor and add it to the status page in the same step.

API Feature Comparison

| Feature | UptimeRobot API | Vigilmon API | |---|---|---| | Request format | Form-encoded (x-www-form-urlencoded) | JSON | | Authentication | API key as parameter | Bearer token header | | Create/read/update/delete monitors | Yes | Yes | | Monitor types supported | HTTP, keyword, ping, port, heartbeat | HTTP/HTTPS, TCP port, SSL, heartbeat | | Multi-region consensus config | No | Yes | | Alert contacts via API | Yes | Yes | | Webhook management | Yes (create/delete) | Yes (create/update/delete + delivery history) | | Webhook delivery history | No | Yes | | Status page management | Limited (paid tiers) | Yes, fully | | Response time data | Yes | Yes | | Uptime statistics | Yes | Yes | | Bulk operations | No native batch endpoint | Standard CRUD (script-composable) | | Rate limits (free) | 10 req/min | Higher limits; see docs | | OpenAPI/Swagger spec | Not publicly available | Available |

Developer Experience

Several practical differences affect day-to-day integration work:

JSON everywhere. Vigilmon's consistent JSON approach means one mental model for all requests. UptimeRobot's form-encoded parameters require a context switch — standard HTTP client libraries handle both, but documentation, debugging, and tooling generation all work more cleanly with JSON.

Idiomatic REST verbs. Vigilmon uses GET to read, POST to create, PATCH to update, DELETE to delete. UptimeRobot's v2 API uses POST for most operations, including updates and deletes. This matters less at runtime but adds friction when onboarding new team members to the automation codebase.

OpenAPI specification. An OpenAPI spec enables code generation, automated testing, and Postman collection export. Vigilmon provides one; UptimeRobot does not publicly.

Webhook debuggability. When an incident fires and the notification doesn't arrive, the first question is "did the webhook fire?" Vigilmon's delivery history answers this in one API call. With UptimeRobot, debugging requires checking your receiving endpoint's logs and inferring backward.

Automation Use Cases

Infrastructure Provisioning

When a new service is deployed, monitoring should be created automatically:

# In your deployment pipeline
create_monitor() {
  local name=$1
  local url=$2
  
  curl -X POST https://api.vigilmon.online/v1/monitors \
    -H "Authorization: Bearer $VIGILMON_API_KEY" \
    -H "Content-Type: application/json" \
    -d "{
      \"name\": \"$name\",
      \"url\": \"$url\",
      \"interval\": 30,
      \"regions\": [\"us-east\", \"eu-west\"]
    }" \
    --fail --silent
}

# Called from deployment scripts
create_monitor "checkout-service-prod" "https://checkout.example.com/health"

Monitoring Dashboards

Pull uptime data into internal dashboards:

# Fetch all monitor statuses for a dashboard widget
curl https://api.vigilmon.online/v1/monitors \
  -H "Authorization: Bearer $VIGILMON_API_KEY" | \
  jq '.monitors[] | {name: .name, status: .status, uptime30d: .uptimePercent}'

Incident Runbooks

Runbooks can include API calls to check monitor history:

# During incident response: check when monitoring first detected the issue
curl "https://api.vigilmon.online/v1/monitors/$MONITOR_ID/incidents?limit=1" \
  -H "Authorization: Bearer $VIGILMON_API_KEY"

Conclusion

UptimeRobot's API works and has served many teams well, but it carries design decisions from an earlier era of web APIs — form-encoded requests, non-standard verb usage, and limited programmatic visibility into alert delivery.

Vigilmon's API was built REST-first with JSON throughout, standard Bearer authentication, webhook delivery history, and a full OpenAPI specification. For teams building monitoring automation into CI/CD pipelines, infrastructure-as-code workflows, or custom dashboards, this translates to cleaner integration code and better debuggability.

The monitoring capability underneath also differs: Vigilmon's multi-region consensus means fewer false-positive alerts reaching your automation — an important property when those alerts are driving automated incident creation or runbook execution.
