# Vextorium Wash Trading Trend Detector

> Vextorium Wash Trading Trend Detector is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-19).

Analyzes whether a token's volume authenticity (organic score) is improving, degrading, or stable by comparing current metrics against snapshots taken ~1h, ~6h, and ~24h ago.

## 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 vextorium-wash-trading-trend-detector-ccf1e594 -d '<json body>'
```

Example prompt: Is the volume authenticity for the Bonk token on Solana getting better or worse? Check the wash trading trend using address DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263.

## When to prefer this

Use this endpoint when you need to understand the temporal trajectory of a token's wash trading risk — not just a point-in-time score but whether conditions are getting better or worse. Prefer this over static organic score endpoints when making time-sensitive trading or liquidity decisions, or when monitoring a token portfolio for emerging wash trading patterns over hours or days.

## Known failure modes

- Missing or invalid token address returns an error
- Unsupported network value outside the allowed enum causes rejection
- First query always returns NO_REFERENCE trend since no historical snapshots exist yet
- Token with insufficient on-chain data may return incomplete comparisons
- Network not specified may default incorrectly if token exists on multiple chains

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

Returns the trend direction (STABLE, IMPROVING, DEGRADING, or NO_REFERENCE on first query), the token's current organic score, comparisons against ~1h/~6h/~24h snapshots, number of saved snapshots, token symbol, and network. On first query, tracking begins with hourly snapshots saved for 7 days.
