Lookup Block Info
Retrieve detailed block information from the BSV blockchain.
API
Uses WhatsOnChain for complete block data (size, txcount, difficulty, previousblockhash). JungleBus /v1/block_header/get/{hash} only provides header fields - use that directly if you only need hash, height, time, merkleroot.
When to Use
- Get block data by height
- Get block data by hash
- View block statistics (size, tx count, etc.)

How to use this skill
Install lookup-block-info by running npx skills add b-open-io/bsv-skills --skill lookup-block-info in your project directory. Run the install command above in your project directory. The skill file will be downloaded from GitHub and placed in your project.
No configuration needed. Your AI agent (Claude Code, Cursor, Windsurf, etc.) automatically detects installed skills and uses them as context when generating code.
The skill enhances your agent's understanding of lookup-block-info, helping it follow established patterns, avoid common mistakes, and produce production-ready output.
What you get
Skills are plain-text instruction files — not executable code. They encode expert knowledge about frameworks, languages, or tools that your AI agent reads to improve its output. This means zero runtime overhead, no dependency conflicts, and full transparency: you can read and review every instruction before installing.
Compatibility
This skill works with any AI coding agent that supports the skills.sh format, including Claude Code (Anthropic), Cursor, Windsurf, Cline, Aider, and other tools that read project-level context files. Skills are framework-agnostic at the transport level — the content inside determines which language or framework it applies to.
