docs: PZERO OpenAI-compatible apiBase example

Issue Category

Undocumented feature or missing documentation

Affected Documentation Page URL

https://docs.continue.dev/customize/model-providers/top-level/openai

Issue Description

The OpenAI page already documents provider: openai plus apiBase for compatible hosts. The "OpenAI API compatible providers" list has no named PZERO example, so users guess the host, key format, and whether to force /chat/completions.

PZERO is prepaid inference. Venice-only upstream. Bearer pzero_ key. Sign-in free. Usage paid. Min top-up 1 USDC on Base. No starter credits.

This is separate from the hosted MCP connector (already filed as a docs example for MCP). This request is the OpenAI-compatible chat path Continue already supports.

Expected Content

A named PZERO row or snippet on that page:

name: PZERO
version: 0.0.1
schema: v1

models:
  - name: PZERO
    provider: openai
    model: deepseek-v4-flash
    apiBase: https://api.pzero.studio/v1
    apiKey: pzero_YOUR_KEY
    useResponsesApi: false

apiBase is the /v1 root, not /v1/chat/completions. useResponsesApi: false keeps Continue on POST /v1/chat/completions for this model. PZERO also serves POST /v1/responses if a later Continue path wants it.

Get a key: https://pzero.studio/agents

Live text ids (public, no key): GET https://api.pzero.studio/v1/models

I am not asking for a first-party Continue provider. provider: openai + apiBase is the existing seam.

Every AI Credit is at least 20% off $1 list. Usage is paid. Do not start implementation on my behalf until the board says Ready; the YAML is for users today.

Open the OpenAI-compatible providers page at https://docs.continue.dev/customize/model-providers/top-level/openai and find the existing provider examples. Add a named PZERO example using the supplied YAML, API base, key placeholder, and chat-completions setting, then verify that the page explains where to get a key and what the /v1 base represents.
