## 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 intel-halowerk-com-label-storage-a8ec5301 -d '<json body>'
```

Example prompt: Save the labels 'exchange', 'hot-wallet', and 'high-risk' for the Base address 0xAbCd1234...5678 in my private namespace.

## When to prefer this

Use this endpoint when you need to privately annotate blockchain addresses with your own custom labels that are isolated from other users. It is ideal for building private intelligence databases, tagging counterparties, or enriching address records with human-readable metadata scoped to your own paying wallet identity. Prefer this over public labeling or read endpoints when the goal is to write new label data.

## Known failure modes

- More than 10 labels submitted — rejected with validation error
- Label string exceeds 40 characters — rejected with validation error
- Unsupported chain specified — rejected with enum validation error
- Address string outside 32–44 character range — rejected with validation error
- Payment not completed or verified — access denied
- Labels array empty — rejected with minItems constraint

## How this service works

Speichert höchstens zehn Labels ausschließlich im Namensraum des Zahlers. Die verifizierte Zahleradresse ist der Eigentümer; Ergebnisse und gespeicherte Daten sind strikt auf diesen Zahler begrenzt.

## Output

Returns confirmation that up to 10 labels have been stored against the specified blockchain address, scoped exclusively to the paying wallet's namespace. The stored data is private and only accessible by the same paying address.
