Description
Cross-rail spend tracking for AI agents — Visa IC, Mastercard Agent Pay, Stripe ACP, x402, and ACH in one dashboard.
Usage Guidance
This skill appears coherent and limited to reporting agent transactions to the PayRail402 API. Before installing: 1) Verify you trust the service endpoint (the code defaults to a railway.app host while README refers to payrail402.com); confirm the TLS certificate and operator. 2) Use the least-privilege credentials: prefer a per-agent webhook token for single agents, and create scoped API keys for multi-agent setups. 3) Avoid sending sensitive payment data (full card numbers, unmasked PII) in the description or metadata — only send the minimal transaction fields required. 4) Rotate keys/tokens regularly and limit webhook token reuse across agents. 5) If you need stronger assurance, contact the operator or verify the npm SDK / homepage references exist (the README references an npm package and docs) and audit the remote API behavior on a test account before giving production tokens.
Capability Analysis
Type: OpenClaw Skill
Name: payrail402
Version: 1.0.2
The skill's purpose is to track AI agent financial transactions, and its implementation aligns with this stated goal. The `openclaw-skill.js` code uses standard web requests to a single, specified HTTPS endpoint (`payrail402-production-2a69.up.railway.app`). It explicitly avoids filesystem access, shell commands, and external dependencies, which is verifiable in the code. Credentials are handled securely via HTTP headers or URL path segments over HTTPS. The documentation (`SKILL.md`, `README.md`) is purely informational and contains no prompt injection attempts or instructions for malicious behavior. While the `baseUrl` is configurable, allowing a potential misconfiguration vulnerability, the skill itself does not exhibit any malicious intent or actions.
Capability Tags
Capability Assessment
Purpose & Capability
The name/description (agent spend tracking across payment rails) aligns with the declared env vars (webhook token, API key, agent ID) and the tools provided (track, register, status). Requested credentials map to the described auth flows (webhook token for single-agent ingest; API key + agent ID for multi-agent/status).
Instruction Scope
SKILL.md and openclaw-skill.js instruct only HTTP requests to the service endpoint and tool calls for tracking/registration/status. The instructions do not ask the agent to read files, execute shell commands, or access other unrelated environment variables or system state. The code only constructs JSON HTTP requests and returns responses.
Install Mechanism
There is no install spec (instruction-only skill with a single JS file). Nothing in the package pulls arbitrary executables or downloads code at install time. The skill relies on runtime HTTP calls only.
Credentials
The three required env vars are proportionate: a per-agent webhook token (primary credential) or an API key + agent ID for multi-agent setups. The agentId is documented as a non-secret identifier. No unrelated secrets or broad cloud credentials are requested.
Persistence & Privilege
The skill is not marked always:true and does not modify other skills or system-wide settings. It asks for no persistent system-level privileges beyond normal skill configuration.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install payrail402 - After installation, invoke the skill by name or use
/payrail402 - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.2
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.
v1.0.1
- Updated documentation to clarify that most non-payment operations (balance check, transactions, budgets, API key management) are now dashboard-only.
- Added details about the /proxy/pay endpoint, including how to specify URL, method, headers, and body.
- Revised funding workflow: users now complete payment via the dashboard after requesting a fund order; programmatic `currentBalance` is only available via the funding endpoint.
- Updated quick reference table to reflect current API capabilities and dashboard-dependent actions.
- Noted API rate limits and reiterated security best practices for API key handling.
v1.0.0
- Initial release of Payrail402 skill for managing x402 payment wallets.
- Enables provisioning, funding, balance checking, and automated payments for x402 API calls via cloud.payrail402.com.
- Guides first-time setup, including wallet creation, initial Stripe funding, and API key configuration.
- Supports proactive balance monitoring, user notifications, and quick access to funding links when balance is low.
- Provides proxy endpoint for seamless paid API calls and transaction history viewing.
