Check that the API process is running
GET
/healthzA liveness check for load balancers and uptime monitors. It answers 200 with an empty body for as long as the API process is running. It does not check the chain data or the services behind the API; use /readyz for that.
There is nothing to send.
Response
The API process is running. The body is empty and the answer is never cached.
Cost
Free. It uses no credits and does not count toward your per-IP rate limit. Only the looser ceiling shared by every caller on your network applies, and above it you get 429 rate_limited.
Errors
None besides that 429. If the process is down, you get no answer at all.
