一次 API 请求用多少 token？在 3 个任务上实测

curl https://api.cheaptokens.dev/v1/chat/completions \

Summarize this incident report in two sentences.

On Tuesday between 14:05 and 14:50 UTC the checkout API returned errors for about 6% of requests. The cause was a configuration change deployed at 13:58 that lowered the database connection pool from 50 to 5 connections per instance. Under normal load nobody noticed, but when the afternoon traffic peak arrived, requests queued for a free connection and timed out after 30 seconds. The on-call engineer saw the growing p99 latency at 14:12, found the change in the deploy log at 14:31 and rolled it back at 14:44. To prevent a repeat, the pool size is now validated in CI against a minimum value, and an alert fires when more than 20 requests wait for a connection for two minutes.
