nc://impossibl

Impossibl: one OpenAI-compatible key for 100+ models from OpenAI, Anthropic, Google, xAI, DeepSeek, Moonshot, Z.ai, Qwen, MiniMax and more. A Nodecode rewrite of impossiblco/hermes-impossibl by impossiblco.

With it, /connect offers Impossibl, /models lists its models, and a turn on impossibl/<creator>/<model> goes to https://api.impossibl.com/v1 over the OpenAI chat wire, which is what the gateway speaks.

Impossibl's /v1/models answer is no plain listing: every model names the endpoints it serves in endpoints, and whether it takes tool calls in supports_tools. A Nodecode turn always offers tools, so only the models serving /v1/chat/completions that do not declare supports_tools: false are listed; image, speech, transcription, embedding and rerank models are left out. A catalog that cannot be read, or that names no such model, leaves the core's own listing standing, so a degraded picker is never an empty one. Set chat_only to false to list every model the core reads.

Ported from the Hermes provider plugin of the same name. See NOTICE.

Get it

Tell the agent "add the impossibl cell", or run nodecode add nc://impossibl.

Set it up

Make a key at https://impossibl.com. Save it with /connect, or set IMPOSSIBL_API_KEY; a saved key wins over the variable, and no other variable's key is ever sent to Impossibl.

The section is on unless it says "enabled": false:

{
  "impossibl": {
    // where Impossibl is served; a relay's address goes here
    "base_url": "https://api.impossibl.com/v1",
    // list only the models routed through chat completions that take tools
    "chat_only": true,
    // one catalog read's ceiling, in seconds
    "timeout_seconds": 8
  }
}

The plugin's IMPOSSIBL_BASE_URL variable is this section's base_url: a base the section does not serve is a relay's catalog, not Impossibl's, and its models are then listed as the core reads them.

Use it

/models, pick Impossibl, pick a model. Without a key the fallback roster is still listed — eleven flagships across the labs Impossibl fronts, the plugin's own fallback_models — so the picker has something to offer before the live catalog answers.
