Description

ReqKey enhances the API you control by incorporating key features such as API key authentication, usage credits, rate limiting, and analytics for requests. It operates with your custom middleware, which performs a single verification call for each incoming request; in this process, ReqKey checks the validity of the caller’s key, subtracts a usage credit from the consumer's balance, imposes their rate limit, and logs the request along with details like status code, latency, and location. Notably, it does not act as a proxy, gateway, or require any DNS modifications, ensuring that it does not introduce additional latency into your critical operations. The average validation time is under 5 milliseconds, and the credit system is designed to be per consumer, meaning that issuing a second key to a customer does not increase their quota, keeping balances consistent across different regions. Additionally, ReqKey offers features such as shadow limits, managed overages, reusable plans, alerts for low credits, and detailed logs that can be filtered by endpoint, status, consumer, and time period. In terms of usage tracking and billing, ReqKey accurately meters and monitors usage while allowing you to retain control over your own billing infrastructure. It also provides software development kits (SDKs) for various programming languages including Python, Node.js, Go, Rust, PHP, .NET, and Java, along with framework adapters compatible with FastAPI, Express, Django, and more, ensuring seamless integration into your existing applications. By offering this comprehensive suite of functionalities, ReqKey empowers developers to manage their APIs with greater flexibility and insight.

Description

Solvimon replaces home-built billing code. It is one API-first system for usage metering, pricing, quote-to-cash, invoicing, payments, and revenue recognition. Send raw events (tokens, API calls, agent actions) via API or ingest them from Snowflake, BigQuery, Redshift, S3, GCS, or Azure Blob Storage. Solvimon aggregates them against meters, prices them with whatever model you sell (seats, usage, credits, commits with overages, outcome-based, or all of it on one contract), and produces the invoice. Payments run through Stripe, Adyen, or Checkout.com, so no PSP lock-in. Tooling: REST API, SDKs, frontend components, a CLI, and an MCP server for agent-driven billing operations. Sandbox available without a sales call. The team previously built billing at Adyen (€1T+ processed volume). Pricing changes ship as configuration, not as a rewrite of your invoicing pipeline.
