Providers

Synthetic

Synthetic exposes Anthropic-compatible endpoints. OpenClaw bundles it as the synthetic provider and uses the Anthropic Messages API.

Property Value
Provider synthetic
Auth SYNTHETIC_API_KEY
API Anthropic Messages
Base URL https://api.synthetic.new/anthropic

Getting started

  • Get an API key

    Get a SYNTHETIC_API_KEY from your Synthetic account, or let onboarding prompt you for one.

  • Run onboarding

    bash
    openclaw onboard --auth-choice synthetic-api-key

  • Verify the default model

    Onboarding sets the default model to:

    text
    synthetic/hf:MiniMaxAI/MiniMax-M2.5

    • Config example

    json5
    {  env: { SYNTHETIC_API_KEY: "sk-..." },  agents: {    defaults: {      model: { primary: "synthetic/hf:MiniMaxAI/MiniMax-M2.5" },      models: { "synthetic/hf:MiniMaxAI/MiniMax-M2.5": { alias: "MiniMax M2.5" } },    },  },  models: {    mode: "merge",    providers: {      synthetic: {        baseUrl: "https://api.synthetic.new/anthropic",        apiKey: "${SYNTHETIC_API_KEY}",        api: "anthropic-messages",        models: [          {            id: "hf:MiniMaxAI/MiniMax-M2.5",            name: "MiniMax M2.5",            reasoning: false,            input: ["text"],            cost: { input: 0, output: 0, cacheRead: 0, cacheWrite: 0 },            contextWindow: 192000,            maxTokens: 65536,          },        ],      },    },  },}

    Built-in catalog

    All Synthetic models use cost 0 (input/output/cache).

    Model allowlist

    If you enable a model allowlist (agents.defaults.models), add every Synthetic model you plan to use. Models not in the allowlist are hidden from the agent.

    Base URL override

    If Synthetic changes its API endpoint, override the base URL:

    json5
    {  models: {    providers: {      synthetic: {        baseUrl: "https://new-api.synthetic.new/anthropic",      },    },  },}

    OpenClaw still appends /v1 automatically.
