[Feature Request] docs: PZERO BASE_URL example (do not append /v1)

[cursor]

🥰 Feature Description

NextChat already overrides the OpenAI host with BASE_URL (README default is https://api.openai.com, without /v1, because NextChat appends /v1). People looking for prepaid, privacy-first inference still have to guess the host, key format, and that adding /v1 themselves produces /v1/v1 and 404s.

Search for pzero returned none. I am not asking for a first-party PZERO provider.

🧐 Proposed Solution

A named PZERO example in the env / custom-endpoint docs.

OPENAI_API_KEY=pzero_YOUR_KEY
BASE_URL=https://api.pzero.studio

Do not set BASE_URL=https://api.pzero.studio/v1. NextChat appends /v1. The chat path is not the base.

In Settings → custom endpoint, same host (https://api.pzero.studio) and a pzero_ key. Model: deepseek-v4-flash (or any live text id from GET https://api.pzero.studio/v1/models, public, no key).

Get a key: https://pzero.studio/agents (sign-in free; min top-up 1 USDC on Base; no starter credits).

Smoke against the host NextChat will call after appending /v1:

curl -sS -X POST "https://api.pzero.studio/v1/chat/completions" \
  -H "Authorization: Bearer $PZERO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"deepseek-v4-flash","messages":[{"role":"user","content":"Hello from PZERO"}],"stream":false}'

If a build does not append /v1 and 404s on https://api.pzero.studio/chat/completions, then that build wants the /v1 root. The README default (https://api.openai.com) is the no-/v1 shape.

I am not asking for a bundled provider. Do not start implementation on my behalf until the board says Ready; the env vars are for users today.

The BASE_URL default in the README uses https://api.openai.com without /v1 precisely because the client appends it, so the pzero example must match that exact form to prevent the double /v1 404 on the /chat/completions path from the curl test.
