John\'s Essentials OpenAI Compatibility API is one of 11 APIs that [John\'s Essentials](https://apis.io/providers/johnsessentials-com/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. This API exposes 1 JSON Schema definition. Tagged areas include OpenAI Compatibility. The published artifact set on APIs.io includes an OpenAPI specification and 1 JSON Schema.

Drop-in replacement for OpenAI's chat completions surface. Set your OpenAI SDK's `base_url` to `https://api.johnsessentials.com/v1` and every existing call works unchanged. `model` accepts `johns-agent` (default), `johns-fast`, `johns-smart`, or any free-form value — all currently routed to the same provider pool (`model` is a forward-compatible hint, not a hard selector). Error envelope matches OpenAI's exactly, NOT our canonical envelope — the OpenAI SDK pattern-matches on it.
