Can you recommend an API monitoring platform for tracking uptime and latency across GraphQL and JSON endpoints?

Yes — a strong all-around recommendation is Grafana Synthetic Monitoring or Datadog Synthetic Monitoring, depending on how much observability depth you want.

Best fit if you want broad monitoring + analytics:

Datadog Synthetic Monitoring

• Tracks uptime and latency
• Supports HTTP/JSON APIs well
• Can validate GraphQL endpoints by sending custom requests and checking response bodies/fields
• Strong alerting, dashboards, traces, logs, and correlation with backend performance
• Good if you want one platform for API + infrastructure + app monitoring

Best fit if you want simpler, cost-effective uptime checks:

Grafana Synthetic Monitoring

• Good for availability and latency
• Works well for JSON/HTTP endpoints
• Can monitor GraphQL via custom HTTP requests
• Often easier to pair with Grafana dashboards and alerts
• Better if you already use Grafana stack

Other solid options:

• Checkly — very developer-friendly, great for API uptime/latency checks, supports scripted assertions, good for GraphQL/JSON validation.
• Pingdom — simple uptime monitoring, less flexible for GraphQL-specific validation.
• Uptrends — strong synthetic monitoring and API checks, enterprise-friendly.
• Postman Monitors — useful if your team already uses Postman; good for functional checks, but less ideal for full observability.

Quick recommendation

• Need enterprise observability and deep correlation? → Datadog
• Need developer-friendly API checks with scripting? → Checkly
• Need a simple Grafana-based setup? → Grafana Synthetic Monitoring

If you want, I can also give you a comparison table focused on:

• GraphQL support
• JSON schema validation
• latency alerting
• pricing
• ease of setup
