Dev Api Health Check
by AgentTools in Onchain & crypto
Probe a GET endpoint several times and report status codes and latency statistics (min/avg/max). The cheap way for an agent to verify an API — for example one found on the x402 Bazaar — responds before spending real money calling it. Use this when an agent needs to status and latency stats — test an API before relying on it.

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.005.
