Version History
PayRail402 1.0.2 - Launch cross-rail spend tracking skill for AI agent transactions across Visa Intelligent Commerce, Mastercard Agent Pay, Stripe Agent Credit Platform, x402 blockchain payments (USDC on-chain), and ACH. - Three tools: payrail402_track (submit transactions for budget enforcement and anomaly detection), payrail402_register (self-register agents and receive pr4_xxx API credentials), payrail402_status (check agent claim state and configuration). - Two auth paths: webhook token (single-agent, zero-config) or API key (multi-agent setups with shared credentials). - Zero dependencies, single HTTPS endpoint, no filesystem or shell access. Full permission justification and security documentation included. - Links to PayRail402 dashboard, @payrail402/sdk on npm, MCP server for Claude/VSCode, and .well-known/agent-card.json for A2A discovery.
What This Skill Does
PayRail402 tracks financial transactions made by AI agents across Visa Intelligent Commerce, Mastercard Agent Pay, Stripe ACP, x402 (USDC on-chain), and ACH. It connects to a central dashboard for budget enforcement, anomaly detection, and cross-rail reconciliation.
Instead of building separate reporting integrations for each payment rail, it routes all agent transactions through one dashboard with built-in budget rules and anomaly detection.
When to use it
- Tracking agent purchases across multiple payment rails in real time
- Enforcing per-transaction and monthly spend limits on autonomous agents
- Flagging anomalous charges when an agent spends 3x its historical average
- Reconciling on-chain USDC payments alongside traditional ACH transfers
- Auditing an agent's full transaction history after a billing dispute
Example Workflow
Here's how your AI assistant might use this skill in practice.
User asks: 'My agent just paid $49.99 to OpenAI via Stripe, track it'
- 1Calls payrail402_track with amount=49.99, description='API usage payment', merchant='OpenAI', rail='stripe_acp'
- 2PayRail402 records the transaction and updates the agent's cumulative spend stats
- 3Budget rules are evaluated against configured per-transaction and daily limits
- 4Anomaly detection compares the amount against the agent's historical average
- 5Dashboard is updated and any violations trigger alerts to the owner
Transaction logged with full metadata, budget rules evaluated, and dashboard updated in real time
