User Guide

Quickstart

Create a key, choose a billing mode, and send your first auditable request.

Choose a Usage Plan

Use PAYG Credit for production traffic and Builder Flow for personal exploration, prototypes, and agent experiments.

The two modes are kept separate so subscription activity does not silently consume production credits.

Supported API Protocols

EveryRouter exposes OpenAI Chat Completions, OpenAI Responses, Anthropic Messages, Gemini native routes, embeddings, images, audio, and video generation routes.

Where a provider does not support a capability, the router fails closed instead of hiding a policy downgrade.
