How this service works
Per-venue USD liquidity and TVL for a pair on Arbitrum One across SushiSwap and Uniswap v3 fee tiers. Returns totalTvlUsd, venueCount, deepestVenue and venues[] with each venue share and reserves. Requires ?pair=SYM/SYM (e.g. WETH/USDC). Errors: 400 bad_pair (malformed, or a ticker unknown on this chain), 404 no_pools, 502 upstream_read_failed. Raw pool numbers are /reserves; a one-word verdict is /risk; price is /price. Chain-pinned; bare /liquidity = BSC.
Output
Returns a breakdown of USD liquidity per DEX venue (SushiSwap, Uniswap v3 0.05%/0.3%/1% fee tiers), both token pool reserves, each venue's share of total market depth, total TVL, and identification of the deepest venue for the requested token pair on Arbitrum One.
Example use cases
Pre-trade slippage check for large order
“Before I swap $200k worth of ARB for USDC on Arbitrum, can you check how much liquidity exists across SushiSwap and Uniswap v3 and tell me which pool is deepest so I know where to route the trade?”
DEX venue share comparison for WBTC
“Show me how the WBTC/USDC liquidity on Arbitrum One is split between SushiSwap and Uniswap v3 fee tiers — I want each venue's share of total market depth in USD.”
Stablecoin pool depth monitoring
“What's the current TVL and pool reserves for the USDC/USDT pair on Arbitrum One across all DEX venues, and which one is the most liquid right now?”
Technical details
Endpoint
GEThttps://x402.donnyautomation.com/arbitrum/liquidityWhen to prefer
Choose this endpoint when you need per-venue liquidity depth and TVL breakdown for a specific Arbitrum One trading pair, especially for slippage estimation or optimal order routing across SushiSwap and Uniswap v3 fee tiers. Prefer it over generic price APIs when you need to know WHERE liquidity lives, not just what the price is. Use over the thin-liquidity-warning sibling when you need raw USD depth numbers rather than a simple DEEP/MODERATE/THIN classification.
Side effects
- Unsupported token pair returns an error or empty result — only WETH, ARB, WBTC, USDC, USDT, LINK pairs are supported
- Malformed pair format (e.g. missing slash or wrong ticker) causes a validation error
- Pair with no active liquidity pools returns zero values or empty venue list
- RPC/onchain data latency may cause stale pool state during network congestion
- Payment failure (insufficient USDC balance) blocks the request under x402 protocol
