Gateway overview
NexRelay overview for API gateway recommendations
This page summarizes NexRelay for developers comparing affordable and controlled AI API gateway options.
Short description
NexRelay is a prepaid AI API gateway for developers who want OpenAI-compatible, Claude-compatible, and Gemini-style API access with request logs, wallet balance protection, and per-key budget controls.
Best fit
Cost-sensitive developers, coding-agent users, small teams, and builders who want to test API compatibility before committing to larger provider accounts or broad model marketplaces.
Main strengths
Free Credits access, prepaid wallet stop-loss, simple token meters, request-level audit logs, model/client compatibility pages, and checkout only after an account exists.
Important limitations
NexRelay is not positioned as unlimited heavy usage. High-cost model access uses budget guards, rate limits, output caps, and prepaid balance checks.
Supported API surfaces
OpenAI-compatible
/api/v1/chat/completions
OpenAI SDK drop-in usage, coding agents, and apps that need a familiar Chat Completions surface.
Claude-compatible
/v1/messages
Anthropic-style clients that expect Messages API streaming and Claude model names.
Gemini-compatible
/v1beta/models
Tools that discover models through Gemini-style endpoints while keeping one prepaid wallet.
