APIClaw

The API layer for AI agents. One key for everything.

10,000+ installs. 26,700+ discoverable APIs. 1,654 callable. Intelligent LLM Gateway.

APIClaw is in early release. Core features are live and actively expanding. Provider coverage, routing intelligence, and catalog depth grow with every update.

curl -fsSL https://apiclaw.cloud/install.sh | bash

Adds APIClaw as an MCP server in your Claude, Cursor, or any MCP-compatible agent. Register your email to unlock 50 calls/month.

Install APIClaw and your agent gets tools to discover and call APIs directly:

discover_apis("weather data for Stockholm")
-> Weatherstack, Visual Crossing, AccuWeather, OpenWeather...

call_api("frankfurter", "latest", {"from": "USD", "to": "SEK"})
-> { "rates": { "SEK": 10.85 } }

The agent handles everything through MCP tools. Works in Claude Desktop, Cursor, Windsurf, OpenClaw, and any MCP-compatible client.

Generate an sk-claw- API key at apiclaw.cloud/workspace and use APIClaw as an LLM gateway from any application:

curl api.apiclaw.cloud/v1/chat/completions \
  -H "Authorization: Bearer sk-claw-..." \
  -H "Content-Type: application/json" \
  -d '{
    "model": "anthropic/claude-sonnet-4-6",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

Humans in the terminal, scripts, CI. Ships with @nordsym/apiclaw:

npx @nordsym/apiclaw login                    # OTP auth, terminal-native
npx @nordsym/apiclaw setup                    # auto-detect Claude, Cursor, Windsurf
apiclaw discover "send SMS to Sweden"         # search registry
apiclaw-http                                  # stand up local HTTP gateway

All three interfaces route through the same api.apiclaw.cloud gateway. One billing pipeline, one logging pipeline, one registry.

One endpoint. Automatic provider routing. The gateway selects the optimal provider based on your workspace settings:

Providers routed through the gateway:

• Groq -- Ultra-fast inference (Llama, Mixtral, Gemma)
• Mistral -- European models (Small, Large, Codestral)
• Together AI -- Open-source models (DeepSeek, Qwen, Llama)
• OpenRouter -- 800+ models as fallback (GPT, Claude, Gemini, etc.)

Override per-request with X-APIClaw-Route: fastest or target a provider directly: X-APIClaw-Route: groq.

The Intelligent Gateway is in its first release. Routing logic, provider coverage, and model support are actively expanding.
