What is Settld MCP Payments?
The Settld MCP Payments skill provides a standardized bridge between AI agents and the Settld ecosystem, allowing for the seamless execution of paid tools via the Model Context Protocol. By integrating this skill into Openclaw Skills, developers can grant their agents the ability to discover premium services and interact with them using a secure x402 challenge, authorize, and retry flow. This ensures that agents can handle financial transactions for data or services autonomously while maintaining strict security and auditability.
This skill is particularly valuable for complex workflows where agents require access to high-quality, paid data sources like Exa Search or real-time weather APIs. Every transaction processed through this integration for Openclaw Skills produces audit-grade artifacts and receipts within Settld, ensuring that all agent spending is transparent and verifiable by the tenant administrator.
Settld MCP Payments Use Cases
- Executing premium data searches through paid API integrations like Exa.
- Accessing real-time, paid weather data with transparent pricing structures.
- Managing the full agreement lifecycle including creation, evidence submission, and settlement.
- Generating cryptographic payment receipts for enterprise compliance and auditing.
How Settld MCP Payments Works
- The agent discovers available paid tools under the settld namespace.
- When a paid tool is invoked, the skill triggers an x402 challenge-response flow to authorize the transaction.
- The skill validates the quote and ensures the call stays within authorized bounds.
- Upon successful payment, the skill executes the tool and returns verifiable settlement headers.
- Detailed receipts and audit artifacts are automatically generated and stored in the Settld dashboard.
