APIClaw
by nordsym
APIClaw is an MCP server that gives AI agents unified access to 18 direct-call providers (AI/LLM, voice, SMS, email, search, code, dev tools), 1,636 open APIs, and 22,392+ discoverable APIs — with built-in authentication, rate limiting, and usage tracking.
API Discovery: Search APIs via natural language, browse by category, and retrieve detailed specs (including compact formats to save context tokens)
Direct API Calls: Execute calls to 18 pre-configured providers without managing API keys or configuration
Capability-Based Routing: Describe an action (e.g., "send SMS", "search web") and APIClaw automatically selects the best provider with fallback support
API Chaining: Build multi-step workflows with sequential, parallel, conditional, and loop execution — including async chains, webhooks, per-step retry logic, and resume-from-failure
Dry-Run Testing: Preview any API call without real execution to test and debug workflows
Workspace & Billing: Register for a workspace, monitor usage/costs/rate limits, manage team access, check credit balance, add credits, purchase API access, and set up metered pay-per-call billing
Multi-Client Support: Works with Claude Desktop, Claude Code, Cursor, Windsurf, Cline, Continue, and Codex (OpenAI)
Allows privacy-focused web searching to retrieve information without tracking through the Brave Search API.
Provides real-time speech-to-text and transcription capabilities across multiple languages.
Enables high-quality text-to-speech generation, realistic voices, and voice cloning in 29 languages.
Provides tools to manage repositories, issues, pull requests, and actions through the GitHub API.
Provides access to Google Search data and real-time SERP results for information retrieval.
Provides access to over 1,000 machine learning models for tasks including image, video, and audio generation.
Enables programmatic sending of emails with high deliverability through a developer-friendly API.
Facilitates global SMS and programmable messaging services across more than 180 countries.
APIClaw 🦞
Your agent calls real APIs. You sign in once.
Start
set up https://apiclaw.cloud/SKILL.mdOr pick a path directly:
# Local MCP (Claude Desktop, Cursor, Windsurf, OpenClaw)
npm install -g @nordsym/apiclaw && npx @nordsym/apiclaw auth login
# CLI
npx @nordsym/apiclaw call nasa/apod --params '{}'
# HTTP gateway
curl https://api.apiclaw.cloud/v1/execute -H "Authorization: Bearer sk-claw-..."
# Remote MCP
https://apiclaw.cloud/mcpThe auth flow opens the browser, signs the user in, and writes ~/.apiclaw.toml. The same credential works across every path.
Headless server or SSH session? Open the browser sign-in URL on a device where you can complete ownership verification.

What it is
APIClaw is the authenticated execution and discovery layer for AI agents. An agent reaches it through SKILL.md, local MCP, CLI, HTTP, or Remote MCP, signs in once through the browser, discovers APIs by capability, and executes calls with credentials kept server-side. 26,619 API definitions discoverable, 1,025 callable now.
Route across supported models from OpenAI, Anthropic, OpenRouter, xAI, Groq, Mistral, Cohere, DeepInfra, or a configured endpoint. Switch with one parameter, no SDK swap, no lock-in.
Numbers
26,619 discoverable API definitions
689 exact-name source-verified entries. Source verification is discovery evidence, not proof of execution.
22 built-in providers, 22 customer-executable provider rails
1,003 workspace-authenticated public/no-key HTTPS origins
1,025 total callable now
Source verification is not execution.
Pricing
Plan | Price | Access |
Free APIs | $0, no card | Free forever. Discovery and every zero-cost API, over 1,000 of the 1,025 callable. |
Paid APIs | Provider cost + 15% | Add a card once, then metered per call. Actions without an exact billing adapter remain blocked. |
Pricing canon: underlying provider cost plus a 15% margin. Stripe metered billing live.
