What is NEAR JSON-RPC Skill?
The NEAR JSON-RPC Skill is a specialized tool designed for AI agents and developers to interface with the NEAR blockchain safely. By leveraging the uxc execution engine and a curated OpenRPC schema, it provides a structured way to query on-chain data without the complexities of manual wallet management or transaction signing. It is a cornerstone for building blockchain-aware applications within the Openclaw Skills ecosystem.
Built with a focus on reliability, this skill defaults to high-performance public RPC providers like FastNear. It bypasses the limitations of non-discoverable RPC endpoints by using a fixed schema URL, ensuring that your AI agent always has a strictly typed map of the NEAR blockchain's read surface. This approach minimizes errors and ensures that data extraction is consistent and high-quality.
NEAR JSON-RPC Skill Use Cases
- Automating blockchain data monitoring and chain status reports.
- Querying real-time account states and balances for NEAR protocol users.
- Retrieving finalized block and chunk data for indexing or analysis.
- Checking current gas prices and validator sets for network health assessments.
- Building read-only dashboards and notification systems for NEAR-based dApps.
How NEAR JSON-RPC Skill Works
- The skill utilizes the uxc CLI as the underlying execution engine to handle networking and error logic.
- It connects to a NEAR RPC provider (defaulting to FastNear) using a curated OpenRPC schema for method discovery.
- Users or agents issue commands via a linked CLI alias, such as near-jsonrpc-cli.
- The skill validates the requested operation against the read-only guardrails to ensure security.
- JSON-formatted blockchain data is returned, structured for easy parsing by automated systems.
NEAR JSON-RPC Skill Setup
To start using this member of the Openclaw Skills library, ensure uxc is installed, then link the skill with the following command:
uxc link near-jsonrpc-cli https://free.rpc.fastnear.com --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/near-jsonrpc-skill/references/near-public.openrpc.json
Verify the installation by checking the help menu:
near-jsonrpc-cli -h
NEAR JSON-RPC Skill Data Schema & Taxonomy
The skill organizes blockchain responses into a consistent JSON envelope. It is recommended to parse stable fields in the following order:
| Field | Description |
|---|---|
ok |
Boolean indicating if the RPC call succeeded |
data |
The primary payload containing the blockchain state |
error |
Detailed error information if ok is false |
kind |
The type of response or error returned |
protocol |
Versioning information for the RPC response |
NEAR JSON-RPC Skill Advanced Features
- Multi-provider support: Easily override the default endpoint to use private or archival RPC nodes.
- Positional Parameter Mapping: Uses
--input-jsonto handle complex positional null or default parameters like block_id. - Schema-driven Discovery: Utilizes a remote OpenRPC schema to enable full CLI autocomplete and help documentation for all NEAR read methods.
- Error Guardrails: Built-in logic to identify and avoid deprecated endpoints and unauthorized transaction attempts.
