## 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 parallax-wallet-payer-dossier-1e91d9ae
```

Example prompt: Pull up the Parallax dossier for wallet 0x4a8f3c2e1d9b7a6f0c5e8d2b4a1f9e7c3d5b8a2f — I want to know their label (organic, operator, self-test, or unseen), how much USDC they've spent, what they buy most, and whether they belong to an operator cluster.

## When to prefer this

Use this endpoint when you need a full behavioral profile of a specific wallet in the x402 payment ecosystem — not just a transaction count but a labeled, evidenced classification with spend breakdown, cadence, basket, and cluster membership. Prefer this over generic blockchain explorers when you need x402-specific analytics with semantic labels and operator graph context.

## Known failure modes

- Address not found or unseen in the index returns label 'unseen' with zero spend and null cluster
- Malformed or non-0x-prefixed address returns a 400 validation error
- Payment failure or insufficient USDC balance returns 402 Payment Required
- Address with very recent activity may fall outside the current indexed window, yielding partial coverage
- Rate limiting or overload may return 429 Too Many Requests

## How this service works

Payer dossier for one wallet over the indexed window: label (organic / operator / self-test / unseen) with evidence, USDC spent, purchases, sellers paid, facilitators used, cadence class, active days, top-5 basket and the operator cluster if there is one.

## Output

A JSON dossier envelope containing: as_of timestamp, frame, coverage, method, attribution, tier, window_days, and a fact object with: label (organic/operator/self-test/unseen), confidence score, evidence array, total USDC spent, cadence class, top-5 basket items, active day count, sellers paid, facilitators used, and operator_cluster identifier if applicable.
