What This Skill Does

The AgentAPI skill provides OpenClaw agents with direct, programmatic access to the AgentAPI directory, a comprehensive hub of over 50 machine-readable and MCP-compatible APIs. This skill acts as a dynamic bridge between your agent and a vast ecosystem of tools ranging from LLM inference providers like Gemini and OpenAI to utility services like Twilio, Supabase, and Firecrawl. The standout feature of this integration is its native support for the x402 payment protocol. By utilizing USDC on the Base blockchain, the skill enables autonomous agents to perform pay-per-use transactions without the need for human-managed API keys or recurring subscription overheads, effectively allowing agents to self-provision the services they need on-the-fly.

Installation

To integrate this capability into your environment, run the following command in your terminal: clawhub install openclaw/skills/skills/gizmo-dev/agentapi-hub

Use Cases

• Autonomous Research: An agent can search the directory for real-time web search APIs, invoke them to gather market data, and pay for the specific queries using the x402 protocol.
• Agent Infrastructure Scaling: When an agent requires additional intelligence, it can locate, verify, and authenticate with an LLM provider such as Groq or Gemini without needing manual pre-configuration of static API keys.
• Multi-Service Workflow Orchestration: Chain together various APIs—such as using Firecrawl to scrape a website, a vector database like Pinecone to index the data, and an LLM to generate a summary—all managed through the AgentAPI directory's standardized interfaces.

Example Prompts

1. "Find me an MCP-compatible API that can perform web scraping and tell me its estimated price per request."
2. "Search the AgentAPI directory for communication services like Twilio or Slack and explain how I can pay for them using USDC."
3. "List all available AI model APIs that support x402 billing and help me draft an initial request structure for a Gemini chat completion."

Tips & Limitations

• x402 Awareness: Ensure your agent wallet is funded with sufficient USDC on the Base network before attempting to use APIs marked as pay-per-use.
• Verification: Always verify the payment recipient and response headers during the initial 402 handshake to avoid potential transaction errors.
• Standardization: Since all APIs are MCP-compatible, favor requests that leverage the ?mcp=true parameter to ensure maximum compatibility with the OpenClaw agent ecosystem.
