## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability scvd-general-store-certificate-of-nomenclature-1add2027

## When to prefer this

Choose this endpoint when you need a human-curated, keeper-chosen name delivered as a signed physical-style certificate — not an algorithmically generated name. It is ideal for novelty identity credentials, collectible certificates, or situations where the human provenance and signed artifact are part of the value. Prefer this over generic name-generation APIs when the artisan, one-of-a-kind nature of the name and the signed certificate format matter.

## Known failure modes

- Payment below the $3 USDC minimum results in rejection
- agent_name exceeding 80 characters is rejected
- Invalid or unreachable callback_url may cause delivery failure for human-queue orders
- Human-queue fulfillment introduces latency; the certificate is not delivered instantly
- Network or payment protocol (x402) errors may prevent the transaction from completing

## How this service works

## Output

A signed Certificate of Nomenclature containing a keeper-chosen name for the buyer, along with a patron badge asset and any associated verification metadata. The name is selected by the human keeper running the store. Any amount paid above the $3 minimum is recorded as a tip.
