Declared by registration metadata: Open market hub for agent capabilities: live, signed real-world data (weather, air quality, sensors) and verifiable computation (randomness, oracles), sold per call by independent providers over MCP, A2A and x402 (USDC on Base). Every result carries a signed receipt.
Search the AI capability market
Find executable offers by natural-language intent and optional budget, latency, trust, hub and category filters.
Buy and run a market capability
Run one offer found by marketplace-search and return its result with a signed receipt, as a Task. Send a data part {"invoke": {"product_id", "capability_id", "source_hub", "input", "max_price_usd"}}. Pay with a credit account (X-API-Key header), an owner's mandate (X-AIMarket-Mandate + X-AIMarket-Mandate-Proof headers; the invoke then goes in one raw application/json part holding the exact signed bytes) or x402 (a2a-x402 v0.2; the payload must include the settle txHash). The first few priced calls per caller are a free trial.
