ApiGo
ApiGo
ApiGo is a hosted AI model gateway for developers and teams building applications with language models. It provides a unified API endpoint for sending requests to supported model providers, with OpenAI-compatible request formats and model selection through a shared interface. The service includes model routing and fallback configuration, API key management, request and usage logs, per-model token pricing, workspace balance controls, and dashboards for reviewing consumption. Developers can use documented setup guides to connect coding assistants and agent tools such as Cursor, Claude Code, Codex CLI, OpenCode, Kimi Code, and OpenClaw. ApiGo is intended for teams that want to manage model-provider access, usage, and billing through one hosted gateway rather than configure each provider separately.Starting Price: $0.10/1M input tokens -

BlackBit VOID
BlackBit
BlackBit VOID is a hosted AI inference gateway and OpenAI-compatible API for developers, security teams, and researchers. It provides a shared endpoint and web console for using a catalog of language and multimodal models, including models aimed at authorized cybersecurity testing alongside general coding and reasoning models. Teams can create API keys, browse model capabilities and per-token rates, try requests in a playground, manage usage and prepaid credits, and connect compatible SDKs, IDEs, and agent frameworks. Common uses include application development, code review, security research, and authorized red-team workflows. VOID is accessed through its hosted API and browser console, with model-specific pay-as-you-go token pricing rather than a fixed subscription. Security testing should be limited to systems users own or are authorized to assess.Starting Price: $0.06/1M input tokens
