## About

plaingateway is an LLM API gateway: one key and one OpenAI-compatible API for every major model, billed at the provider's list price with 0% fee on credits. It uses the OpenRouter API, so you switch by changing the base URL. Own keys are free.

It serves models from Anthropic, OpenAI, DeepSeek, Z.ai, MoonshotAI and others through one API.

The API matches OpenRouter: the same paths, request fields, response shapes, model ids and errors. You switch by changing the base URL and the key. OpenAI-compatible and Anthropic-compatible endpoints are both served.

Each model has one pinned host. The X-PG-Host header names the host on every response. Every response also carries its cost.

We do not store prompts or answers, and we do not train on them. Each host keeps data under its own policy, and the model page names the host.

Inference is billed at the provider's list price. OpenRouter also bills list price, and charges a 5.5% fee when you buy credits. We charge 0% fee on credits. The Free plan runs on your own provider keys, with no fee, no cap and no card. Credits are prepaid, from $5.

## Key features
