Three Ways to Use APIClaw

1. MCP Server (Agent Discovery + Calling)

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.

2. Intelligent Gateway (OpenAI-compatible endpoint)

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"}]
  }'

3. CLI

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:

Routing Mode	Behavior
fastest	Lowest latency (Groq, Mistral)
best_price	Cheapest available provider
highest_quality	Best model quality
balanced	Weighs speed, cost, and quality

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.

Discoverable vs Callable

Discoverable (26,704 APIs) -- Every API in the index. Your agent can search, read specs, and evaluate them. Free and unlimited.

Callable (1,654 APIs) -- APIs your agent can actually execute through APIClaw. Two types:

• Open APIs (1,635) -- No authentication required. APIClaw calls them directly.
• Managed Providers (19) -- APIClaw owns the keys. You call, APIClaw authenticates.
