ORYNX: one API for every frontier model

Add one provider per API format to ~/.openclaw/openclaw.json. OpenClaw replaces ${ORYNX_API_KEY} with that environment variable, so set it in the environment OpenClaw runs in.

~/.openclaw/openclaw.json

{
  models: {
    mode: "merge",
    providers: {
      orynx: {
        baseUrl: "https://api.orynx.dev/v1",
        apiKey: "${ORYNX_API_KEY}",
        api: "openai-completions",
        models: [
          { id: "kimi-k3", name: "Kimi K3", input: ["text", "image"], contextWindow: 1048576, maxTokens: 131072 },
        ],
      },
      "orynx-claude": {
        baseUrl: "https://api.orynx.dev",
        apiKey: "${ORYNX_API_KEY}",
        api: "anthropic-messages",
        models: [
          { id: "claude-sonnet-5", name: "Claude Sonnet 5", input: ["text", "image"], contextWindow: 1000000, maxTokens: 128000 },
        ],
      },
      "orynx-gpt": {
        baseUrl: "https://api.orynx.dev/v1",
        apiKey: "${ORYNX_API_KEY}",
        api: "openai-responses",
        models: [
          { id: "gpt-5.5", name: "GPT-5.5", input: ["text", "image"], contextWindow: 1050000, maxTokens: 128000 },
        ],
      },
    },
  },
  agents: { defaults: { model: { primary: "orynx-claude/claude-sonnet-5" } } },
}

Notes

mode: "merge" adds these providers to the ones OpenClaw ships with instead of replacing them.
Anthropic providers use the host only (https://api.orynx.dev). OpenAI providers use https://api.orynx.dev/v1.
OpenClaw only sends images to models that declare input: ["text", "image"]. Use input: ["text"] for text-only models such as glm-5.3.
ORYNX reads the key from x-api-key or Authorization, so you do not need authHeader.
