What is Jev Proxy Pool?

A self-hostable HTTP proxy that puts one endpoint in front of TypeSafe Jev while rotating through a pool of API keys automatically, so clients call a single URL with a bearer token you control.

What wire format does it expose?

POST /v1/systemone, also available at /api/v1/systemone. It accepts a state and typed questions whose type can be noul, choice or score, and returns model, answers and usage, matching TypeSafe's own shape.

How does key rotation behave?

It rotates through available keys in order with at most 50 upstream calls per key per second, disables a key automatically when TypeSafe returns 401 or 402, and pauses it and switches to another key on 429.

How do I manage the keys?

A web admin panel protected by ADMIN_PASSWORD adds, checks, searches, deletes and imports or exports keys, including a JSONL format. Clients authenticate to the proxy with AUTHORIZATION_TOKEN.

Where are the keys stored?

In Upstash Redis by default, shared by every instance and preserved across redeploys, costing about 3 Redis commands per proxied request. With USE_REDIS=false keys come from the TYPESAFE_API_KEYS variable instead.

How do I deploy the Jev Proxy Pool?

One-click buttons deploy to Vercel with an optional Upstash database, prefilled with the environment variables. Locally it needs Node 22.9 or newer, npm ci, a .env with the admin password, token and Redis details, then npm run dev.

What breaks without Redis?

Each instance enforces the 50 requests per second limit on its own, so several instances can exceed it in total; disabled keys, cooldowns and check results reset on restart and are not shared between instances.

Jev Proxy Pool

A self-hostable HTTP proxy that fronts TypeSafe Jev through one endpoint, rotating your API keys automatically and serving the /v1/systemone wire format. Keys live in Upstash Redis or an environment variable, and a web admin page manages them.

Highlights

One HTTP endpoint rotates TypeSafe API keys, capped at 50 upstream calls per key per second.
Disables keys on upstream 401 or 402 and pauses them on 429, switching to the next key.
POST /v1/systemone accepts noul, choice and score questions and returns model, answers and usage.
Web admin panel adds, checks, searches, deletes and imports or exports keys as JSONL.
Keys live in Upstash Redis by default, or in TYPESAFE_API_KEYS with USE_REDIS=false; one-click Vercel deploy.

Quickstart

bash

curl --fail-with-body 'https://your-project.vercel.app/v1/systemone' \
  -H 'Authorization: Bearer YOUR_AUTHORIZATION_TOKEN' \
  -H 'Content-Type: application/json' \
  --data '{"state":{"text":"Hello"},"questions":{"check":{"type":"noul","instructions":"Does the text contain Hello?"}}}'

Watch out

README and GitHub metadata reviewed 2026-10-17; the repository shows no GitHub language or date metadata in the sweep, so behaviour details come from the README alone. The 50 requests per second limit is per key per instance, not a global guarantee.

Jev at home: voice pipelines, Assist routing, and sentinels

Oct 16, 2026

How Home Assistant conversation agents, macOS voice pipelines, and an advisory sentinel put a fast typed decision in the loop — one call per utterance, thresholds in code, and a daily token budget.

Jev-based SEO tools split the crawl from the call: deterministic crawlers count and parse, while typed judgments rank fixes, place internal links, score search results, and track AI-answer mentions — with costs and caveats attached.

Jev on the Gateways: Vercel, Workers AI, and OpenRouter

Oct 12, 2026

The request shape barely changes across surfaces; the surrounding contract does. When to call the API directly and when a gateway, a Worker binding, or a router entry earns its extra hop.
