# Arbitrum One Thin Liquidity Risk Classifier

> Arbitrum One Thin Liquidity Risk Classifier is a paid API for AI agents from x402.donnyautomation.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-16).

Classifies market depth (DEEP/MODERATE/SHALLOW/VERY_THIN) for an Arbitrum One token pair by analyzing live pool TVL across SushiSwap and Uniswap v3 fee tiers, counting routable venues, and flagging single-venue markets and wide spreads.

## 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 arbitrum-one-thin-liquidity-risk-classifier-d898192c
```

Example prompt: Before I buy a chunk of ARB/USDC on Arbitrum, can you run a liquidity depth check and tell me if the market is DEEP, MODERATE, SHALLOW, or VERY_THIN — and flag if it's dangerously concentrated in a single venue?

## When to prefer this

Choose this endpoint when you need a fast, pre-trade liquidity sanity check specifically for Arbitrum One token pairs across SushiSwap and Uniswap v3. Prefer it over the raw pool reserves endpoint when you want a human-readable classification (DEEP/MODERATE/SHALLOW/VERY_THIN) and venue concentration flags rather than raw numbers. Use it over generic market data APIs when you specifically need Arbitrum DEX depth with multi-venue aggregation and single-venue risk flagging.

## Known failure modes

- Unknown or unsupported token pair symbol returns an error or no-data response
- Pair exists on Arbitrum but has zero TVL across covered DEXs — classified VERY_THIN or returns empty
- On-chain RPC latency may cause stale or failed pool reads
- Misspelled token symbols yield no results
- Pairs not listed on SushiSwap or Uniswap v3 Arbitrum are outside coverage scope

## How this service works

Pre-trade depth verdict for a pair on Arbitrum One: is this market thin enough to hurt you. Returns depthClass DEEP|MODERATE|SHALLOW|VERY_THIN, totalTvlUsd, venueCount, topVenueShare, midSpreadBps, flags. Requires ?pair=SYM/SYM (e.g. WETH/USDC). Errors: 400 bad_pair, 404 no_pools, 502 upstream_read_failed. Depth only - NOT a contract audit or honeypot check. Per-venue detail is /liquidity. Chain-pinned; bare /risk = BSC.

## Output

Returns a depth classification label (DEEP, MODERATE, SHALLOW, or VERY_THIN), live TVL aggregated across SushiSwap and Uniswap v3 fee tiers on Arbitrum One, count of venues capable of routing the trade, concentration percentage in the largest venue, a boolean single-venue flag, and a wide-spread warning flag.
