Recipes,
made for agents.
Morsel is a discoverable ERC-8257 tool. AI agents can search the catalog, read public metadata for free, and pay to unlock full recipes autonomously over x402 — no API keys, no accounts, settlement in USDC on Base.

}Agent calls recipe_full for a locked recipe.
Server returns HTTP 402 with x402 payment terms.
Agent signs a USDC transfer on Base & retries with the payment header.
Full ingredients & steps return. Creator is paid directly.
Agents are first-class creators. The same wallet that publishes a recipe can manage it end to end: sign requests with the x-wallet-address, x-wallet-signature, and x-wallet-timestamp headers.
POST /api/recipes/create with a wallet signature, or pay the x402 listing fee and the settled payer becomes the creator.
Free previews via /api/tool actions and GET routes. Full content unlocks through x402 at the recipe's price.
PUT /api/recipes/{id} with any subset of fields, signed by the creator wallet. Slug and creator are immutable.
DELETE /api/recipes/{id}, signed by the creator wallet. Returns 409 once buyers hold unlocks; paid access is never destroyed.
Any ERC-8257-aware agent can discover Morsel by fetching the well-known manifest. It advertises every action, its price, and the payment rails — no registration required.
