Why CodaURL

A dashboard for you. Structured JSON for your agents.

JSON-first CLI

Every command returns JSON with fields like status_since, previous_status, and error_code, so an agent can decide what to do next.

1-minute checks on Pro

Short outages don't slip between checks. Pro checks every minute. Free checks every 5 minutes.

Status-change alerts

You get an alert when a monitor goes UP or DOWN, not on every failed check.

Pricing

Start free. Upgrade when you need faster checks.

Built for AI agents

Give an agent a dependable signal, a clear contract, and a next action.

Machine-readable by default

Use --json with every CLI command or call the REST API with predictable status, status change, latency, and error fields.

Actionable status changes

Agents can tell whether a monitor is UP, DOWN, or not checked yet without parsing human-facing dashboards.

Human alerts when it matters

Pair agent-readable output with push and email notifications, plus webhooks on Pro, on meaningful status changes.

Put monitoring to work

Practical workflows for your deployments, protected APIs, and application health checks.

Check a deployment with a JSON CLI

Give an AI agent a saved monitor, run a check after release, and read status changes from JSON.

Monitor an authenticated HTTPS API

Use Pro request headers to check a protected health endpoint without returning saved credentials.

Check response keywords and SSL expiry

Add a body assertion on Pro and read separate certificate expiry and validated TLS results.
