## 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-seller-profile-x402-economy-analytics-13e562df
```

Example prompt: Pull the Parallax settlement profile for api.example.com — I want to see their total USDC earned, how many distinct buyers they've had, and what share of purchases came through Coinbase's facilitator versus others.

## When to prefer this

Use this endpoint when you need a comprehensive, read-from-settlement-graph seller profile for a specific x402 participant — covering revenue, buyer behavior, facilitator attribution, and retention metrics in a single call. Prefer this over the funnel or co-purchase sibling endpoints when you want a holistic seller snapshot rather than a single dimension of analysis. Best suited for due diligence, competitive research, or monitoring your own x402 API's economic performance.

## Known failure modes

- Unknown address or hostname returns 404 or empty fact object
- Seller has no indexed activity — returns zero values or null fact
- Malformed address format causes 400 validation error
- Seller indexed under a different host alias than queried — may need canonical hostname
- Data freshness lag — as_of date may be hours or days behind real-time settlement

## How this service works

Not quoted. Not estimated. Read from the settlement graph, stamped with frame and coverage, priced per fact for people and their agents.

## Output

A JSON object containing: total USDC earned by the seller, list of associated hosts, payment destination address, distinct buyer count, total purchase count, per-facilitator attribution shares, organic traffic share, buyer half-life in days, recurring buyer count, coverage tier (full/partial), settlement frame identifier, and the as-of date for the data snapshot.
