Health

Answers 200 as long as the process is up. Does not touch the database: this is the endpoint uptime monitors should poll.

Use /ready instead when you need to know the API can actually serve traffic (deployment gates, smoke tests).

Verifies the API can reach its database (SELECT 1) and answers 200 only then.

Do not poll this. Every call wakes the serverless database and keeps it from suspending, which costs real money. Use it for deployment checks and smoke tests; point your uptime monitor at /health instead.
