├────────────────────────────────────────────────────────┤
│                                                  │
│  1. Agent needs capability                       │
│     → Searches Unbrowse marketplace              │

│  4. Agent executes capability                     │
│     → Calls Twitter internal API directly          │
│     → Completes task in 200ms                   │
│     → Returns value to customer                 │

The Stack

| Component | Role |

|-----------|-------|

| **MCP** | Standardized protocol for agent-to-server communication |

| **Unbrowse** | Turns any website's internal API into callable skill |

| **x402** | Machine-to-machine payment protocol on Solana |

| **Marketplace** | Google for agents - searchable capability index |

Key Insight: Autonomous Resource Acquisition

Before: Agents need human permission for every new capability.

After: Agents discover, evaluate, purchase, and use capabilities autonomously.

This is the missing piece.

Why This Matters

1. Self-Improving Agents

Agents can now:

Discover their own limitations

Find solutions in marketplace

Pay for solutions autonomously

Grow their capabilities without human intervention

2. Agent-to-Agent Economy

Skills published by agents:

Agent A learns Twitter API

Publishes skill for 1 USDC

Agent B pays Agent A

Both profit

3. Merit-Based Capability

Capabilities with value earn USDC:

Good skills → More downloads → More revenue

Bad skills → Fewer downloads → No revenue

The market determines what's valuable.

4. Permissionless Innovation

Anyone can:

Reverse-engineer an API

Publish to marketplace

Earn USDC from other agents

No approval needed
