What is Kash Payment Skill?
The Kash skill is a specialized financial integration for Openclaw Skills designed to give AI agents the ability to fund their own operations. By linking a Kash wallet, agents can handle micro-payments for pay-per-use tools, external LLM providers, and data services without requiring manual user intervention for every cent spent.
This skill provides a secure framework for autonomous spending. It features a dual-layer security model that validates transaction destinations and enforces strict budget limits. By default, any expenditure under $5.00 is handled autonomously, while larger transactions trigger a mandatory user-confirmation request, ensuring a perfect balance between agent efficiency and human oversight.
Kash Payment Skill Use Cases
- Funding pay-per-request web search or scraping tools during research workflows.
- Automating the purchase of tokens for specialized external AI models or APIs.
- Managing operational costs for agents performing data-intensive tasks across multiple providers.
- Implementing strict financial guardrails and spending caps for experimental AI projects.
- Paying for digital assets or cloud services directly through an agent's dedicated wallet.
How Kash Payment Skill Works
- The agent identifies a need to use a paid external service during its task execution.
- The agent calls the
kash_spendtool, providing the required amount, description, and merchant details. - The skill validates the request against local budget caps and server-side limits defined in the Kash dashboard.
- If the transaction exceeds the $5.00 threshold, the skill pauses and requests a YES confirmation from the user.
- Once authorized, the transaction is processed through the Kash API, and a success confirmation is returned to the agent.
- The agent proceeds with the paid service call only after receiving the successful spend confirmation.
Kash Payment Skill Setup
To integrate Kash into your Openclaw Skills environment, configure your ~/.openclaw/openclaw.json file as follows:
{
"skills": {
"entries": {
"kash": {
"enabled": true,
"env": {
"KASH_KEY": "your_kash_api_key",
"KASH_AGENT_ID": "your_agent_id",
"KASH_BUDGET": "50",
"KASH_SPEND_CONFIRMATION_THRESHOLD": "5.00"
}
}
}
}
}
You must obtain your KASH_KEY and KASH_AGENT_ID from the kash.dev dashboard after registering your agent.
Kash Payment Skill Data Schema & Taxonomy
The Kash skill manages financial data and transaction metadata using the following structure:
| Parameter | Description | Required |
|---|---|---|
amount |
The transaction value in USD (e.g., 0.005). | Yes |
description |
A clear string explaining the purpose of the spend. | Yes |
merchant |
The name of the service or API being paid. | No |
confirmed |
Boolean flag indicating explicit user approval for high-value spends. | No |
KASH_BUDGET |

Allowlisted endpoint validation (api.kash.dev). | Yes |
Kash Payment Skill Advanced Features
- Local session budget enforcement that acts as a primary guardrail before reaching server-side limits.
- Automated confirmation logic that prevents unauthorized high-value spending by requiring manual user input.
- Real-time balance monitoring via the
kash_balancetool to allow agents to plan multi-step paid operations. - Strict URL allowlisting to ensure API keys are never transmitted to unauthorized or untrusted domains.
- Integration with the Kash dashboard for remote agent pausing and comprehensive spending analytics.
