REST API authentication

API keys

Create keys in Developer settings. Format: sk_live_… (legacy s0_live_… still accepted).

Authorization: Bearer sk_live_your_key_here
Content-Type: application/json

Keys are shown once at creation. Store securely — never commit to git.

Use with MCP

{
  "mcpServers": {
    "social0": {
      "command": "node",
      "args": ["/path/to/social0-mcp/dist/index.js"],
      "env": {
        "SOCIAL0_API_KEY": "sk_live_your_key_here"
      }
    }
  }
}

Security

• One key per integration (Claude vs Cursor vs CI)
• Rotate immediately if leaked
• MCP runs locally — key stays on your machine's env
• Revoked keys return 401 invalid_api_key
