DEX Trading Volume by Protocol on One Chain (DEX Category)

omnial/chain-dex-volume-by-protocol

For one blockchain, returns DEX trading volume for the DEX category: the chain's volume over the last 24 hours, 7 days, 30 days, one year and all time, the matching earlier periods and percentage changes, and one row per DEX with its name, slug, id, parent protocol, the chains it runs on, the same volume figures and changes on this chain, and its daily average over the past year.

Five steps: search, inspect, learn, run, settle. No per-tool setup; your agent reaches this tool through the meta-tools it already has.

agent

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "omnial/chain-dex-volume-by-protocol" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "omnial/chain-dex-volume-by-protocol" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "omnial/chain-dex-volume-by-protocol", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "omnial/chain-dex-volume-by-protocol", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
