Every tool has an explicit pricing model and a usage guide written for it and checked against its schema.
You pay the price shown. If a call turns out to cost more than its quote, you pay the actual price, capped at twice the quote. Run omnial_execute with dry_run: true for an exact quote.
Search here runs the same omnial_search call your agent makes over MCP: ranked matches, each showing the keyword or field it matched on. It always answers with what it found; an empty result means the catalog carries none of those terms, and the full list is right below.
