About

ReqKey adds API key authentication, usage credits, rate limiting and request analytics to an API you own. Your own middleware makes a single verify call per incoming request: ReqKey validates the caller’s key, deducts a credit from that consumer’s pool, enforces their rate limit, and records the request with status code, latency and location. It never sits in front of your API — no proxy, no gateway, no DNS change — so it adds no hop to your critical path. Validation averages under 5ms. Credits pool per consumer rather than per key, so issuing a customer a second key does not hand them a second quota, and balances stay synced across regions. Also included: shadow limits, controlled overage, reusable plans, low-credit alerts, and per-request logs filterable by endpoint, status, consumer and time range. ReqKey meters and tracks usage — you keep your own billing stack. SDKs for Python, Node.js, Go, Rust, PHP, .NET and Java, with framework adapters for FastAPI, Express, Django, and more.

About

The deduction automation module provides controls, workflow, validation, resolution, and recovery to manage customer deductions effectively. Collection automation forecasts, controls, and manages workflows autonomously, while credit management offers controls, limits, monitoring, and updates to mitigate credit risks.
