What is Mflo?
Mflo is the data kernel for AI agents — a pay-per-query dataset marketplace built on the x402 HTTP standard and EIP-3009 meta-transactions. It provides instant, structured data access for AI agents, bots, and LLMs without requiring API keys or subscriptions.
Powered by the Model Context Protocol (MCP) and x402, Mflo enables on-demand access across any dataset. MCP ensures seamless interoperability with AI agents and LLM ecosystems, while x402 standardizes payments and transport. Together, they make Mflo the foundation for universally accessible data in the age of intelligent agents.
Core Concept
Traditional data APIs require:
- 🔑 API Keys - Complex authentication setup
- 💳 Subscriptions - Monthly commitments regardless of usage
- 🏗️ Integration overhead - Custom SDKs and rate limiting
Mflo uses x402 Payment Required HTTP responses to enable:
- ⚡ Instant access - Pay only for what you query
- 🤖 Agent-native - MCP (Model Context Protocol) integration
- 🔐 Wallet-based auth - Wallet signing, no API keys
- 💰 Micro-payments - Pay per dataset query with stablecoins
How It Works
- AI agent requests data → x402_API server returns
402 Payment Required - Payment prompt → User signs EIP-712 message via Wallet like Metamask
- Payment settlement → EIP-3009 meta-transaction processes payment
- Data delivery → Protected dataset served instantly
Architecture
The Mflo ecosystem consists of:
- x402_DMP (Dataset Marketplace) - Web UI for browsing and testing datasets
- x402_API - Resource server handling payment verification and data serving
- Smart Contracts - EIP-3009 compatible mUSDC testnet stablecoin on Monad Network for payments
- MCP Server - Model Context Protocol integration for AI agents
Key Features
🔗 MCP-Native Integration
Built-in Model Context Protocol server allows AI agents to query datasets directly through natural language.
💸 x402 Pay-Per-Query
HTTP 402 "Payment Required" standard enables micro-payments for individual data requests.
🏦 EIP-3009 Meta-Transactions
Off-chain signed payments settled on-chain without gas fees for users.
📊 Structured Data
All datasets provide schema definitions and sample data for easy agent integration.
🚀 Instant Access
No registration, no API keys — just connect your wallet and start querying.
Use Cases
- AI Agent Data Access — Real-time market data, weather, news feeds
- Research & Analysis — Historical datasets for training and backtesting
- Micro-payment Testing — Demonstrating x402 and EIP-3009 standards
- Decentralized Data Markets — Proof-of-concept for trustless data exchange
