What This Skill Does
A browsable, searchable directory of 50+ APIs built for AI agents. All entries are MCP-compatible and machine-readable. Some APIs are available through x402 pay-per-use using USDC on Base chain.
Unlike general API directories, every listing is verified MCP-compatible and structured for agent consumption rather than human browsing.
When to use it
- Finding an email API that works with your MCP agent
- Discovering vector databases for a RAG pipeline
- Filtering AI inference APIs by speed or pricing
- Looking up which payment processors are agent-compatible
- Comparing communication APIs like Twilio, Slack, and Resend in one place
Example Workflow
Here's how your AI assistant might use this skill in practice.
User asks: find a web search API compatible with my MCP agent
- 1Query the AgentAPI directory with search term 'web search' and filter mcp=true
- 2Parse the returned JSON list of matching APIs
- 3Extract name, pricing, and rate limit fields for each result
- 4Present options like Brave, Exa, and Tavily with their pricing tiers
A ranked list of MCP-compatible search APIs with pricing and rate limit details
Requirements
Accounts, API keys, or tools you or your AI assistant may need to set up while using this skill.
