1List the pools for a token
Query pools by token. The response enumerates each pool with its pair, reserves and TVL. This is a C2 read.
curl "https://api.1st-node.com/v1/market/dex/pools?token=eth" \ -H "Authorization: Bearer sk_live_..."
2Read TVL and reserves per pool
Each pool carries its trading pair, reserves and USD TVL. Rank by TVL to find the deepest venue for the pair you care about.
> { "pools": [
> { "pair": "ETH/USDC", "dex": "uniswap-v3",
> "tvl_usd": 41200000, "reserves": ["8200", "26100000"] } ] }3Size slippage against the deepest pool
Use reserves and TVL to estimate price impact for your trade size, and route to the pool with enough depth. Cache pool metadata but refresh reserves near execution.
