Questions and answers

• How do you keep usage counts and credit enforcement accurate when requests are retried, arrive concurrently, or reach your service during a network outage?

  Yes, ReqKey handles all three:

  Retries: Validation is never retried automatically, so a timeout can’t deduct credits twice. Log retries are tied to the validation’s requestId, so they don’t add usage. Denied requests (402, 403, 429) cost nothing.

  Concurrent requests: Each consumer has one credit pool shared by all its keys, and the check and the deduction happen in a single step. Two requests can’t both spend the last credit.

  Outages: You choose the behavior. Fail closed (the default) returns a 503 so nothing goes through unchecked. Fail open keeps your API running and marks each request that wasn’t metered, so you can record it yourself. Balances stay in sync across regions, and any missed update is fixed within about a second.
