🟢search_kits(q, kind, category, rail, max_price_usd, ...)
Search the Agentropolis index (MCP servers, x402/MPP paid HTTP APIs, A2A agents, kits). Read-only; never pays. Trust scores come only from verified non-wash payments. First-party kits (Featured from Seenly, an affiliated publisher) are returned in a separate labeled block.

}🟢call_kit(id, endpoint, method, body, query, ...)
Forwards your request to the seller's x402 endpoint and returns the seller's response. If the seller answers 402, you get its payment requirements unchanged: sign the payment with YOUR OWN wallet to the seller's payTo, then call again with x_payment (x402 v1) or payment_signature (x402 v2). Agentropolis forwards the payment unchanged, never holds keys or funds, never settles, and charges no fees. Only listings with links.call / buy=relay_x402 are supported.
