01
Opper offers access to over 300 models through a single API key, with hosting options in the EU for better compliance. It is fully compatible with existing OpenAI, Anthropic, and Google SDKs, so switching only requires updating a base URL. The service stands out because many of its providers run inference within Europe, it uses a single EU sub-processor for all models, and it does not store prompts by default. You also get a powerful control plane for routing, PII masking, spend caps, and audit trails. It is built for agents, allowing you to integrate it into tools like Cursor with just one line of code.
02
Auriko functions like a trading desk for LLM providers, using a specialized cost-arbitrage engine to find the best value for every request. Developed by former quantitative traders, the system analyzes your request patterns to select the most efficient inference paths based on token costs, cache performance, latency, reliability, and output quality. Benchmarks show an average cost reduction of 30 percent compared to industry peers. You can view the full source and methodology on their website.
03
Most API tests only confirm a connection, but FetchSandbox allows developers and AI agents to verify complex behaviors like webhooks, retries, and async workflows. It helps you reproduce real bugs and prove your fixes work before you deploy to production. You can connect it to tools like Cursor, Claude Code, and VS Code via MCP. With support for over 60 popular APIs like Stripe and OpenAI, you can test your logic thoroughly without wasting your actual API quota or waiting for a staging environment to be ready.
04
UnitPay is a complete monetization operating system for AI companies. You can use it to design pricing models, run usage-based billing, and track inference costs and margins in real time. It helps you show every customer exactly what value they are receiving. The platform is built specifically for AI-native products, supporting features like credit systems, hybrid pricing, per-token metering, and detailed cost tracking. It is completely free to use until you hit 500,000 dollars in annual recurring revenue.
