Product Price Comparison Across Online Merchants

omnial/x402-price-compare

Given a product name (and an optional 2-letter country code), returns price listings for matching products across online merchants, with a lowest/highest/average price summary, currency, and the total number of offers found. In-stock status appears only on the multi-product result shape; per-offer merchant names, links and shipping are often null.

Use it

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.

For developers: the calls your assistant makes
agent
// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "omnial/x402-price-compare" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "omnial/x402-price-compare" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "omnial/x402-price-compare", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "omnial/x402-price-compare", input: { /* ... */ } })

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