Your AI assistant does the work: it finds this tool, shows you the price first, runs it, and you are charged when the run finishes. There is nothing to set up for this tool in particular.

Connect once and your AI can find and run this tool, and any other it needs.

agent

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

// 2. inspect: price and input schema
omnial_inspect({ tool: "omnial/gas-oracle" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "omnial/gas-oracle" })

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

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