What is GhostScore?
GhostScore is a privacy-first reputation protocol designed for the emerging landscape of autonomous agents. By utilizing Openclaw Skills, developers can seamlessly query on-chain credit tiers earned through x402 micropayments. The system leverages Unlink shielded transfers on the Monad network to ensure that agent interactions, payments, and reputation accrual remain confidential and secure.
This skill serves as a dedicated reputation manager, allowing users to verify the trust level of an agent without exposing sensitive transaction histories. As part of the Openclaw Skills ecosystem, it provides a read-only interface to validate zero-knowledge attestations, ensuring that agents meet specific service requirements while maintaining the highest standards of cryptographic privacy.
GhostScore Use Cases
- Verifying an AI agent's reputation tier before granting access to premium API endpoints.
- Validating zero-knowledge attestations to confirm an agent's creditworthiness without revealing its identity.
- Auditing available service providers and their associated reputation gates within the Openclaw Skills framework.
- Ensuring autonomous agents meet minimum trust thresholds for secure DeFi or cross-chain operations.
How GhostScore Works
- The skill connects to the Monad EVM chain using a provided RPC URL to read the ReputationRegistry contract.
- It retrieves the agent's current reputation score based on historical shielded payments.
- The system maps the numerical score to a specific tier (Tier 0 to Tier 3), determining service eligibility.
- For verification requests, the skill processes ZK attestation objects to confirm signature validity and timestamp accuracy.
- It queries the GhostScore backend to return a curated list of accessible endpoints and their respective costs in USDC.
GhostScore Setup
To integrate this functionality into your environment, configure the necessary environment variables for your Openclaw Skills setup:
# Set the Monad RPC endpoint
export MONAD_RPC_URL="https://your-monad-rpc-url"
# Set your GhostScore API Key
export GHOSTSCORE_API_KEY="your_ghostscore_api_key"
Ensure these variables are accessible to the agent to enable read-only contract queries and API verification.
GhostScore Data Schema & Taxonomy
The skill organizes reputation data and verification proofs using the following schema:
| Property | Description |
|---|---|
score |
On-chain reputation points derived from x402 payments. |
tier |
Level classification ranging from Open (0) to Premium (3). |
attestation |
ZK proof object containing signature, threshold, and signer address. |
endpoints |
List of available provider APIs with their USDC pricing and tier requirements. |
status |
Verification result of the provided cryptographic proofs. |
