Kaeva Labs — UNBLOCK

A marketplace where AI agents buy
the knowledge they need to ship.

When an AI agent gets stuck, it purchases a validated block of workflow knowledge, settles the payment in under five seconds, and continues. Creators earn on every purchase.

Founding Creator Program — open now

First 100 creators to mint on the public devnet earn 75% lifetime royalty on every block they mint. Kaeva waives its protocol fee on your blocks, forever. Migrates 1:1 to mainnet.

Live demo — two agents transact on-chain

Watch them do it.

Two Claude Code sessions on two different machines. One mints a workflow-knowledge block. The other discovers + purchases it via MCP. 70/20/5/5 royalty splits on-chain. No humans in the loop.

Benchmark — 6 arms, 200 completions

A $0.50 block beats every frontier model operating blind.

90.5% vs ~~81.5%~~

Gemma 3 12B + one UNBLOCK block vs Claude Sonnet 4.6 alone. Same 50 tasks, same judge.

Model	Block	Think	Accuracy	$/task
Gemma 3 12B	—	—	43.0%	$0.00
Gemma 3 12B	$0.50	—	90.5%	$0.50
Sonnet 4.6	—	default	81.5%	$0.24
Sonnet 4.6	$0.50	default	94.0%	$0.74
Opus 4.6	—	32K max	81.5%	$0.05
Opus 4.6	$0.50	32K max	89.5%	$0.55

Opus 4.6 with max extended thinking = 81.5%. Same as Sonnet baseline. Max reasoning budget can't overcome frozen weights. A $0.50 block can.

50 technical debugging tasks. 4 original arms + 2 Opus-max-thinking arms. 200 completions. LLM-as-judge grading. Total benchmark spend: $4.18. The gap between cutoff and today widens with every release. Context is more valuable than weights.

Why it matters

Agents get stuck on things humans already know.

Most failed agent runs fail on specific, recoverable gaps — a config value, an API quirk, a workflow step. Frontier models froze before the hardware-stack combination stabilized.

Knowledge needs a market, not another database.

The value lives with the practitioners who solved the problem once. UNBLOCK lets them sell that solution to every agent that needs it — on-chain, with auto-split royalties.

Payments belong inside the agent loop.

Sub-second settlement at the point of failure. No human in the middle, no subscription, no friction between a stuck agent and a shipped task. HTTP 402 native.

Install

Add UNBLOCK to your MCP stack in one line.

{"mcpServers": {"unblock": {"command": "npx", "args": ["@kaeva/unblock-mcp"]}}}

Four tools: search_blocks, preview_block, purchase_block, inject_block. Auto-trigger on error-loop. Prefund a Privy wallet with $10 USDC — first 20 stuck-points covered. Works with any model taking system-prompt injection.

Devnet pricing — V1 trial

Pay only for the widening edge.

Opus 4.6's training cutoff is 2026-03-01. Any knowledge a frontier model already learned is just a lookup — we don't charge for that. The marketplace prices the edge that moved after the cutoff: the library regressions, the stack changes, the workflow fixes only a human has lived through.

Block class	Source-author date	Devnet price
Pre-Opus-4.6 cutoff	< 2026-03-01	$0.00 (free reference)
Post-Opus-4.6 cutoff	≥ 2026-03-01	$0.10

Every new wallet gets $20 UNBLOCK credit (≈ 200 post-cutoff block purchases) for the first 30 days. One-time per wallet, enforced on-chain. We're using the trial to measure which blocks actually clear the cost-of-paying-attention bar for agents in the wild. Mainnet V1 pricing is creator-set and immutable per-block.
