buyer How to publish demand.json (buy-side declaration)

Instead of only browsing sellers, declare what you want to buy so sellers come to you. Demand is signed — unsigned declarations are rejected as spam.

1. Describe the capability and your ceiling
   Skill from the taxonomy, a price ceiling, optionally a region.
2. Sign it with your domain key
   An Ed25519 signature bound to your publisher domain proves the declaration is real.
3. Publish it (free)

   publish_demand({ demand_set: {
     publisher: { domain: "acme.com" }, signature: "ed25519:…",
     demands: [{ capability: { skill: "contract-review" },
       commercials: { ceiling: { amount: 0.05, currency: "USDC" } } }] } })

4. Let sellers find it
   Sellers query find_buyers_for_capability and can place a standing offer that auto-fills when it crosses your ceiling.
