What is PayStabl?

PayStabl is a programmable wallet infrastructure platform that empowers AI agents with autonomous onchain transaction capabilities. It provides CDP-powered smart wallets with policy governance, session controls, and seamless M2M (machine-to-machine) commerce capabilities.

The Problem​

Traditional payment systems weren't designed for autonomous AI agents. Current challenges include:

  • Manual Payment Flows - Agents can't handle payment requests without human intervention
  • No Micropayment Support - High fees make small API payments uneconomical
  • Complex Integration - Each payment provider requires custom implementation
  • Limited Agent Autonomy - Agents can't make purchasing decisions independently

The Solution​

PayStabl enables true autonomous commerce through:

🤖 Agent-Native Design​

  • Programmable wallets designed specifically for AI systems
  • Policy-based spending controls and session management
  • Automatic transaction handling without human intervention

💳 x402 Protocol Integration​

  • Native support for HTTP 402 "Payment Required" responses
  • Automatic payment header generation and request retry logic
  • Seamless integration with existing API architectures

🔗 Inter-Agent Commerce​

  • Direct agent-to-agent payment capabilities
  • Compensation for tool usage, data access, and compute resources
  • Built-in reputation and trust mechanisms

🛡️ Enterprise Security​

  • Gasless transactions via paymaster integration
  • Multi-signature wallet support for team agents
  • Comprehensive audit trails and compliance reporting

Key Features​

Programmable Wallets​

Each agent gets a smart contract wallet with:

  • Configurable spending limits and policies
  • Session-based allowances for temporary operations
  • Multi-sig support for high-value transactions
  • Gas abstraction for seamless user experience

Policy Governance​

  • Spending Limits - Daily, weekly, or per-transaction caps
  • Allowlists - Restrict payments to approved services only
  • Time-based Controls - Enable payments during specific hours
  • Amount Thresholds - Require approval for large transactions

Framework Integration​

Pre-built integrations for popular AI frameworks:

  • Claude MCP Server - Tool-based payment integration
  • LangGraph - Payment-enabled workflow nodes
  • Custom Runtimes - SDK for any agent framework

Use Cases​

API Monetization​

  • Convert existing APIs to paid services with x402 headers
  • Automatic micropayment handling for per-request pricing
  • Dynamic pricing based on usage patterns or demand

Agent Collaboration​

  • Agents paying each other for specialized services
  • Distributed compute marketplaces
  • Data sharing and processing pipelines

Autonomous Services​

  • Self-managing SaaS subscriptions
  • Dynamic resource provisioning
  • Automated vendor payments
