Nefin by Adyrra — Your AI CLI subscription, one API endpoint

Turn the AI CLI subscription you already pay for into one isolated API — tool calling, streaming and vision included.

✓No shared subscriptions
✓Isolated per customer
✓Standard wire format

SCROLL

One request shape

Same request. Any agent. Streamed back.

Point your existing SDK at your tenant. Swap one path segment to change the agent underneath — the request body never changes.

~ / your-app

# same request shape, one endpoint per agent

curl -N -X POST \
  https://api.yourdomain.dev/t/acme/codex/chat/completions \
  -H "Authorization: Bearer $TENANT_API_KEY" \
  -d '{
    "stream": true,
    "messages": [{"role": "user", "content": "Summarize this repo"}]
  }'

Streaming response

Nefin wraps your own Codex, Claude Code, Gemini CLI, or Grok subscription behind one isolated, standard chat API — tool calling, streaming, and vision included.

Features

Everything a CLI-agent-backed API needs

One standard chat API on the outside, your own isolated CLI agent on the inside.

One familiar chat API

Drop-in /chat/completions shape, the same for every backend agent — point your existing SDK at it.

Tool & MCP calling

Bridge your own MCP servers — execution stays on your side, we just relay the decision.

Real token streaming

Genuine Server-Sent Events, sourced from live agent deltas — not a fake buffered stream.

Vision input

Send images inline in chat messages, the same familiar way modern vision APIs work.

Full tenant isolation

Every customer gets a dedicated, sandboxed environment — never shared compute.

Bring your own subscription

Your Codex, Claude Code, Gemini, or Grok login stays yours — we never hold or share your credentials.

Comparison

Why not just call each CLI directly?

You could wire up every agent's own interface one by one. Flip the switch to see what that costs you versus one gateway.

Architecture

One request, fully isolated end to end

Your request hits one control plane, which routes it to your own dedicated environment — running your own chosen agent. No step in between is shared with another customer.
