Use it only for listings whose search result has buy='relay_x402' (links.call present); for any other listing, call the seller directly using get_kit_manifest. Flow: call without payment, receive HTTP 402 with the seller's payment requirements unchanged, sign a payment with your own wallet to the seller's payTo, then call again with payment_signature (x402 v2) or x_payment (v1). Agentropolis holds no keys or funds, never changes payTo or amount and charges no fee, but a signed payment you pass is forwarded and may be settled by the seller, so real money can move. Limits: seller's own https host only, 256 KB request, 2 MB response, 25 s timeout (longer for slow first-party kits), 20 calls/min per client.
