# AgentAPI A curated directory of APIs designed for AI agents. Machine-readable. MCP-compatible. Agent-accessible. **Website:** https://agentapihub.com **Docs:** https://api.agentapihub.com/api/docs ## Free Features The directory and search functionality is **completely free**: ```bash # Browse all APIs (FREE) curl https://agentapihub.com/api/v1/apis # Search by capability (FREE) curl "https://agentapihub.com/api/v1/apis?q=send+email&mcp=true" # Filter by category (FREE) curl "https://agentapihub.com/api/v1/apis?category=ai" ``` ## x402 Pay-Per-Use APIs Some APIs are available through **x402** — a pay-per-use protocol using USDC on Base chain. ### Available x402 APIs | API | Endpoint | Approx. Price | |-----|----------|---------------| | Gemini Chat | `/api/gemini/chat/completions` | ~$0.001/req | | Gemini Embeddings | `/api/gemini/embeddings` | ~$0.0005/req | ### How x402 Works 1. Call the API endpoint 2. Receive `402 Payment Required` with price details 3. Send USDC payment on Base chain 4. Retry request with payment proof 5. Receive API response ### ⚠️ Important Safety Notice **x402 payments require explicit setup and should not be automated without safeguards:** - **Wallet required:** You must configure a wallet with USDC on Base - **User approval recommended:** Implement confirmation flows before any payment - **Verify recipient:** The payment recipient is `0xcCb92A101347406ed140b18C4Ed27276844CD9D7` (gizmolab.eth) - **Set spending limits:** Configure maximum per-request and daily limits - **This skill does not auto-execute payments** — it provides documentation only For implementation details, see: https://api.agentapihub.com/api/docs ## Directory Categories | Category | APIs | Example | |----------|------|---------| | Search | Brave, Serper, Exa, Tavily, Perplexity | Web search with AI summaries | | AI & ML | OpenAI, Claude, Gemini, Groq, Replicate | LLM inference, image gen | | Communication | Resend, Twilio, Slack, Discord, Telegram | Email, SMS, messaging | | Database | Supabase, Pinecone, Qdrant, Neon, Upstash | SQL, vectors, KV store | | Payments | Stripe, Lemon Squeezy, PayPal | Payment processing | | Scraping | Firecrawl, Browserbase, Apify | Web scraping, automation | | Developer | GitHub, Vercel, Linear, Sentry | Code, deploy, issues | | Productivity | Notion, Google Calendar, Todoist | Tasks, scheduling | ### MCP-Compatible APIs All 50+ APIs in the directory are MCP-compatible.
