## 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 halowerk-intel-address-label-discovery-6a288501
```

Example prompt: Can you look up the labels and identity information for the blockchain address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE — I want to know what category it falls into and how confident the data is?

## When to prefer this

Choose this endpoint when you need to resolve the identity or classification of a specific blockchain address and want confidence scores and source attribution alongside the label. It is particularly useful for on-chain due diligence, transaction enrichment, or compliance workflows where you need to know whether an address belongs to a known exchange, protocol, or entity. Unlike generic blockchain explorers, results are private and scoped to your paying address.

## Known failure modes

- Address not found or unlabeled — returns empty result set
- Invalid address format — request rejected with error
- Payment verification failure — result withheld until payment confirmed
- Rate limiting or quota exceeded for the paying address
- Address exists but has no known labels in the database

## How this service works

Identischer Alias der Adressklassifikation für x402-Discovery. Die verifizierte Zahleradresse ist der Eigentümer; Ergebnisse und gespeicherte Daten sind strikt auf diesen Zahler begrenzt.

## Output

Returns occupied labels, names, categories, data sources, and confidence scores associated with the queried blockchain address. Results are strictly scoped to the authenticated paying wallet address and may include custom labels alongside aggregated third-party data.
