How this service works
Raw AMM pool state for a pair on Arbitrum One: v2 reserves and v3 concentrated liquidity across SushiSwap and Uniswap v3 fee tiers. Returns pools[] with venue, surface, feeBps, reserveA, reserveB, price and tvlUsd at a stated blockNumber. Requires ?pair=SYM/SYM (e.g. WETH/USDC). Errors: 400 bad_pair, 404 no_pools, 502 upstream_read_failed. For USD depth already computed use /liquidity. This is the underlying numbers. Chain-pinned; bare /reserves = BSC.
Output
Returns per-venue pool data for each fee tier and AMM on Arbitrum One: both token reserves, the pool mid price, fee tier in basis points, USD TVL, and the block number at which data was captured. Covers constant-product (SushiSwap) and concentrated-liquidity Uniswap v3 pools in a single response.
Example use cases
Price impact calculation before large trade
“I'm about to swap 500,000 USDC for WBTC on Arbitrum — can you fetch the raw pool reserves and TVL for WBTC/USDC across all Uniswap v3 fee tiers and SushiSwap on Arbitrum One so I can calculate my price impact?”
Cross-venue arbitrage opportunity detection
“Get me the live pool state and mid price for ARB/USDC on every available venue on Arbitrum One — I want to see if there's a spread between SushiSwap and the different Uniswap v3 fee tiers I can exploit.”
Onchain liquidity snapshot for reporting
“Fetch the current pool reserves and USD TVL for WETH/USDC across all Arbitrum One AMM pools and tell me which venue has the deepest liquidity right now.”

Endpoint
GEThttps://x402.donnyautomation.com/arbitrum/reservesWhen to prefer
Choose this endpoint when you need the raw underlying pool reserve numbers on Arbitrum One to do your own quote, price impact, slippage, or arbitrage math — rather than a pre-computed best price. It covers multiple venues (SushiSwap + Uniswap v3 multi-tier) in one call and is L2 Arbitrum-specific. Prefer sibling endpoints for pre-computed best execution price or thin-liquidity warnings.
Side effects
- Unknown or unsupported token pair symbol returns an error or empty result
- Token pair with no deployed pools on Arbitrum One returns empty venues array
- Malformed pair string (e.g. missing slash separator) returns a validation error
- Temporary RPC or onchain data unavailability may cause timeout or stale data
- Unsupported token ticker not resolvable to a contract address returns an error
