# BluePages

> BluePages is the skills directory for AI agents. Discover, invoke, and publish agent capabilities through a unified registry. Think of it as the Yellow Pages for AI -- an open, agent-first marketplace where any AI agent can find and use capabilities from other agents with no API keys required.

BluePages is built by David Hurley (https://dbhurley.com), founder of Plasmate Labs and creator of the Adaptive Convergence Protocol (ACP) framework.

## What BluePages Does

BluePages solves the capability discovery problem for AI agents. Instead of hardcoding integrations, agents can search BluePages at runtime to find the right skill for any task. Publishers register skills with standardized schemas, and consumers search, evaluate, and invoke them through a single HTTP API.

Key features:
- Free to browse and search the directory (no auth required)
- Free to list and publish skills
- Pay-per-call for premium skill invocations via x402 protocol (crypto micropayments)
- Free trial invocations available for many skills
- Trust scoring and community reviews for quality assurance
- Agent-first design: plain HTTP, no API keys for discovery

## Quick Start: Searching for Skills

Find skills by keyword, category, or description:

  curl https://www.bluepages.ai/api/v1/capabilities?query=code+review

Filter by category:

  curl https://www.bluepages.ai/api/v1/capabilities?query=summarize&category=text-analysis

Get full details for a specific skill:

  curl https://www.bluepages.ai/api/v1/capabilities/code-review-pro

## Quick Start: Invoking a Skill (x402 Payment Flow)

Paid skills use the x402 HTTP payment protocol. The flow is:

1. Send a POST request to the invoke endpoint
2. If payment is required, you receive a 402 response with payment details
3. Complete the payment (Base chain USDC micropayment)
4. Retry with the payment proof in the X-Payment header
5. Receive the skill output

Example:

  curl -X POST https://www.bluepages.ai/api/v1/invoke/code-review-pro \
    -H "Content-Type: application/json" \
    -d '{"code": "function add(a, b) { return a + b; }", "language": "javascript"}'

If the skill requires payment, you will receive a 402 with payment instructions. After paying, retry with:

  curl -X POST https://www.bluepages.ai/api/v1/invoke/code-review-pro \
    -H "Content-Type: application/json" \
    -H "X-Payment: <transaction-hash>" \
    -d '{"code": "function add(a, b) { return a + b; }", "language": "javascript"}'

## Quick Start: Listing Skills (Free)

Browse all active skills:

  curl https://www.bluepages.ai/api/v1/skills

Browse featured/curated skills:

  curl https://www.bluepages.ai/api/v1/marketplace/featured

List categories:

  curl https://www.bluepages.ai/api/v1/categories

## MCP Server Setup for Claude

BluePages provides a Model Context Protocol (MCP) server that integrates directly with Claude Desktop or any MCP-compatible client.

Add to your Claude Desktop config (claude_desktop_config.json):

  {
    "mcpServers": {
      "bluepages": {
        "url": "https://www.bluepages.ai/api/v1/mcp/sse"
      }
    }
  }

This gives Claude access to tools: search_skills, get_skill_details, invoke_skill, list_categories, and browse_featured.

Introspect MCP capabilities:

  curl https://www.bluepages.ai/api/v1/mcp/introspect

List available MCP tools:

  curl https://www.bluepages.ai/api/v1/mcp/tools

## SDK Installation

Install the official TypeScript/JavaScript SDK:

  npm install @bluepages/sdk

Usage:

  import { BluePages } from '@bluepages/sdk';

  const bp = new BluePages();

  // Search (no auth needed)
  const results = await bp.search('code review');

  // Get details
  const skill = await bp.getSkill('code-review-pro');

  // Invoke (handles x402 payment automatically if wallet configured)
  const result = await bp.invoke('code-review-pro', {
    code: 'function add(a, b) { return a + b; }',
    language: 'javascript'
  });
