# Parallax Seller Analytics

> Parallax Seller Analytics is a paid API for AI agents from parallax402.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

Returns settlement analytics for a single x402 seller over the indexed window, including USDC revenue, purchase count, distinct buyers, organic share, recurring buyers, buyer half-life, and facilitator mix.

## 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-analytics-7ffcf2f0
```

Example prompt: Pull the Parallax seller analytics for my wallet 0xAbC1234567890abcdef1234567890abcdef123456 — I want to see settled USDC, distinct buyers, organic share, recurring buyers, half-life, and the facilitator breakdown.

## When to prefer this

Use this endpoint when you need a comprehensive, single-seller funnel view from the x402 settlement graph — specifically when you want organic-share-adjusted buyer counts, recurring buyer rates, half-life estimates, and facilitator attribution all in one call. Prefer it over the economy-wide census endpoint when the query is seller-specific rather than ecosystem-wide, and over the payer dossier endpoint when the subject is a seller rather than a buyer wallet.

## Known failure modes

- Unknown seller address or hostname returns no data or empty result
- Malformed 0x address (wrong length or non-hex) causes validation error
- Seller exists but has no indexed activity within the window, returning zeroed metrics
- Network or upstream indexer unavailability causes timeout or 5xx
- Missing required `seller` query parameter returns 400 bad request

## How this service works

The funnel, honestly, for one seller over the indexed window: settled USDC and purchases, distinct buyers, organic share after self-test exclusion, recurring buyers, buyer half-life and the facilitator mix.

## Output

A JSON envelope containing: as_of timestamp, frame identifier, coverage and method metadata, attribution tier, window_days, and a fact object with payTo address, host list, settled USDC, purchase count, distinct buyer count, organic_share (fraction after self-test exclusion), recurring_buyer count, half_life_days, and per-facilitator share breakdown.
