# apexfaucet.xyz Volume Check — Wash Trade & Round-Trip Analysis

> apexfaucet.xyz Volume Check — Wash Trade & Round-Trip Analysis is a paid API for AI agents from apexfaucet.xyz, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-02).

Analyzes a Solana/X1 token mint's trading volume to distinguish real demand from wash trading, arbitrage, and market-making by identifying wallets that bought and sold the same token within a configurable time window.

## 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 apexfaucet-xyz-volume-check-wash-trade-round-trip-analysis-85e81d54
```

Example prompt: Can you check whether the volume on token Du6Z596DwGnfUcMSyRHSBQzNybiQKu8GESVfruEv9Jqr is real demand or mostly wash trading — look at the last 48 hours and show me which wallets are doing the most round-tripping?

## When to prefer this

Use this endpoint when you need to assess the authenticity of a token's trading volume on X1/Arc — specifically to detect wash trading, arbitrage loops, or market-maker activity. It is purpose-built for on-chain round-trip analysis with configurable time windows up to 7 days, making it ideal for due diligence, listing decisions, or monitoring suspicious volume spikes.

## Known failure modes

- Invalid or unrecognized mint address returns an error
- hours parameter out of range (< 1 or > 168) causes validation failure
- Token with no trading history returns empty or zero volume data
- Network or RPC issues may cause timeouts for highly active tokens
- Payment failure ($0.004 USDC x402) blocks the request

## How this service works

Is this token's volume real demand? 24h round-trip analysis: how much volume came from wallets buying and selling the same token back and forth (wash trading, arbitrage or market making) versus one-way trades, with the top round-trippers and pool liquidity. Optional ?hours=1..168.

## Output

Returns a breakdown of total trading volume split into round-trip (wash/arbitrage/market-making) volume versus one-way organic volume, the top wallets by round-trip activity, and pool liquidity data — all for the specified token mint over the requested time window (default 24h).
