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

Example use cases
Route large swap on Optimism
“I'm about to swap a large amount of WETH for USDC on Optimism — can you tell me which DEX has the deepest liquidity and the biggest share of total market depth so I know where to route it?”
Stablecoin pool depth check
“Before I provide liquidity, can you check the current TVL and pool reserves for USDC/DAI on OP Mainnet across SushiSwap and Uniswap v3?”
Slippage risk assessment for OP token
“I need to estimate slippage for a trade in the OP/USDC pair on Optimism — can you pull the live market depth and per-venue liquidity so I can see if the pool is thin or well-funded?”
Technical details
Endpoint
GEThttps://x402.donnyautomation.com/optimism/liquidityWhen to prefer
Choose this endpoint when you need live, per-venue DEX liquidity data specifically on Optimism (OP Mainnet) for order routing, slippage estimation, or liquidity analysis across SushiSwap and Uniswap v3 fee tiers. Prefer it over generic price endpoints when you need pool reserves, market depth shares, and TVL rather than just a mid-price. Use sibling endpoints for Arbitrum, Polygon, Avalanche, or BSC chains.
Side effects
- Unsupported token pair returns an error or empty result — only WETH, OP, WBTC, USDC, USDT, DAI pairs are reliably supported
- Malformed pair symbol (e.g. missing slash or wrong ticker) causes a validation error
- Payment failure (x402 protocol) blocks the response if USDC balance is insufficient
- Transient RPC or onchain data lag may cause stale or missing pool state
- Pair not found on either SushiSwap or Uniswap v3 returns zero or null liquidity fields
