How this service works
Pre-trade depth verdict for a pair on Polygon PoS: 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. WMATIC/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 liquidity depth classification (DEEP, MODERATE, SHALLOW, or VERY_THIN) for the specified Polygon PoS trading pair, along with total TVL aggregated across QuickSwap, SushiSwap, and Uniswap v3 pools, count of venues able to route the trade, concentration percentage in the largest venue, a boolean flag for single-venue markets, and a wide-spread warning flag.
Example use cases
Pre-trade slippage risk check
“I'm about to make a big WETH/USDC swap on Polygon — can you check the market depth first and tell me if liquidity is DEEP, MODERATE, or THIN across the major Polygon DEXs?”
Single-venue concentration alert
“Check whether WMATIC/USDC on Polygon is dangerously concentrated in just one DEX — I want to know if trading is effectively limited to a single venue before I place my order.”
Automated DeFi bot pre-trade guard
“My trading bot is about to execute a MATIC/DAI trade on Polygon PoS — run a liquidity depth check to confirm it's not a very thin or shallow market before it goes through.”
Technical details
Endpoint
GEThttps://x402.donnyautomation.com/polygon/riskWhen to prefer
Choose this endpoint when you need a pre-trade liquidity risk assessment specifically on Polygon PoS that aggregates across QuickSwap, SushiSwap, and Uniswap v3 in a single call. Prefer it over raw pool reserve endpoints when you want a human-readable classification (DEEP/MODERATE/SHALLOW/VERY_THIN) rather than raw numbers. Use it instead of the Arbitrum or Base equivalents when your trade is on Polygon PoS. It is not a contract audit or honeypot detector — use it solely for depth and venue concentration analysis.
Side effects
- Unknown or unsupported token pair symbol returns an error or empty result
- Pair not found on any of the three supported DEXs returns no pool data
- Stale or temporarily unavailable on-chain data may cause incorrect depth classification
- Misspelled token symbols (e.g. USDC vs USDT) silently return wrong pair data
- Very new or illiquid pairs may return VERY_THIN with minimal TVL detail
