Everything you need to mint validated knowledge blocks, install the MCP server, and integrate x402 payments into your agent loop.
Start here
Install the SDK, prefund a Privy wallet, and run your first search_blocks call in under three minutes.
[ READ ↗ ] 02One-line config for Claude Code, Cursor, and any MCP-aware agent. Auto-trigger on error-loop.
[ INSTALL ↗ ] 03Four tools: search_blocks, preview_block, purchase_block, inject_block. HTTP 402 native.
[ REFERENCE ↗ ] 04First 100 creators earn 75% lifetime royalty. Kaeva waives protocol fees, forever. Migrates 1:1 to mainnet.
[ APPLY ↗ ]01 — Getting started
Everything you need to buy, mint, and inject knowledge blocks. Runs locally — only scrubbed block hashes touch our infra.
pip install unblock-sdk # or npm install @kaeva/unblock-sdk
Create a Privy-backed wallet, prefund with $10 USDC,
and you're ready to query the marketplace.
02 — MCP server
Add UNBLOCK to your Claude Code, Cursor, or any MCP-aware agent stack:
{
"mcpServers": {
"unblock": {
"command": "npx",
"args": ["@kaeva/unblock-mcp"],
"env": { "UNBLOCK_API_KEY": "..." }
}
}
}
Auto-trigger on error-loop. First 20 stuck-points covered by your prefunded wallet. Sub-$2 purchases auto-approve; above $2 prompts a human.
03 — API reference
search_blocks(query, domain, max_price) — find candidate blocks by symptom or error signature.
preview_block(id) — get tier, price, creator reputation, and symptom teaser without paying.
purchase_block(id) — HTTP 402 settlement. Agent signs from prefunded wallet. Creator earns 70%.
inject_block(id) — decrypt payload and inject directly into the agent's context window.
04 — Founding Creator Program
First 100 creators to mint on the public devnet earn a 75% lifetime royalty (vs. the 70% standard) on every block they ever mint. Kaeva waives its protocol fee on your blocks, forever. Migrates 1:1 to mainnet.
No lockups. No cliffs. Your royalty rate is bound to your creator address, not to any specific block. Mint one block, mint a thousand — the rate travels with you.
