APIClaw 🦞

Your agent calls real APIs. You sign in once.

Start

set up https://apiclaw.cloud/SKILL.md

Or pick a path directly:

# Local MCP on a machine the human can see (Claude Desktop, Cursor, Windsurf, OpenClaw)
npm install -g @nordsym/apiclaw && npx @nordsym/apiclaw auth login

# CLI (only after whoami prints an email)
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/mcp

On headless, Grok, or cloud: show the first-line https://apiclaw.cloud/auth/cli?authId=… URL from unsigned first_run and stop. Do not run auth login there — that opens a browser they will never get. After Authorize, whoami and the first call stay in the same chat. Workspace is optional. Terminal.app is not the product.

auth login on a machine they can see writes ~/.apiclaw.toml. The same credential works across every path.

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, 1,005 callable now.

Route across supported models from OpenAI, Anthropic, OpenRouter, xAI, Groq, Mistral, 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, 3 customer-executable provider rails
• 1,002 workspace-authenticated public/no-key HTTPS origins
• 1,005 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, plus up to 25 managed calls capped at $1 provider cost after login. | | 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.

List an API

Workspace discovery submissions use Catalog > My APIs > Add API: import an OpenAPI URL or JSON/YAML file, save a draft, and submit for operator review. Approved metadata is searchable with discover_apis({ query: "your API", callable_only: false }). Listing does not enable execution, key custody or billing. See the workspace and reviewer guide for limits, release requirements and runnable tests.
