GET /health — ParaLens Server Healthcheck Endpoint - ParaLens

The /health endpoint confirms the server process is running. It does not perform an RPC connectivity check — a healthy response only means the ParaLens service itself is up, not that the underlying Ethereum node is reachable.

Request

curl https://paralens-production.up.railway.app/health

No request body or headers are required.

Response

On success, the server returns a plain-text 200 OK with the body:

ok

Status Codes

Code	Meaning
`200`	Server is running

This endpoint does not validate that the upstream RPC node is reachable. A 200 response here does not guarantee that POST /analyze will succeed. If you need to verify full end-to-end connectivity, submit a known transaction hash to /analyze in your smoke tests.

Use Cases

Deployment platform healthchecks — point Railway, Fly.io, Render, or similar platforms at /health to determine when the container is ready to serve traffic.
Uptime monitoring — configure tools such as UptimeRobot or Better Uptime to poll /health at a regular interval and alert on non-200 responses.
