APIbase
One MCP + REST endpoint to APIbase's live tool catalog (counts: https://apibase.pro/llms.txt). No signup, no subscription, no API key to start — pay per call in USDC (x402 on Base or MPP on Tempo).
Install
npx -y apibase-mcp-clientAPIbase.pro — The API Hub for AI Agents
One MCP + REST endpoint to 1399 tools from 402 providers. No signup, no subscription, no API key to start — pay per call in USDC (x402 on Base or MPP on Tempo).
Quick Start
{
"mcpServers": {
"apibase": { "url": "https://apibase.pro/mcp" }
}
}
That's the Claude Desktop config. Cursor, Windsurf, OpenAI Agents SDK, LangChain, Google ADK, CrewAI, Microsoft Copilot Studio, and plain REST: apibase.pro/connect.
For AI Agents
- llms.txt — concise LLM context
- ai.txt — plain-text agent discovery
- mcp.json — MCP server metadata
- openapi.json — OpenAPI 3.1 spec
- api-catalog — RFC 9727 discovery linkset
- Roadmap — planned/shipped changes that affect what an agent can do or see

Self-Hosting

Architecture
Single Node.js/TypeScript API server, PostgreSQL as the append-only financial source of truth, Redis for cache/rate-limiting only, multi-container Docker stack on one Hetzner server. Every tool call runs the same multi-stage pipeline (escrow-first, idempotent, fail-closed, content-moderated) — dual-rail payments (self-hosted x402 facilitator + MPP), error-code contract, and full container/pipeline detail (exact counts, live): docs/architecture.md.
