What it does

Japanese company search: look up companies in the official JP corporate registry by trade name and/or location. Partial-name match on both the Japanese and registered English name, with width/abbreviation normalization, filterable by prefecture, city, and corporation kind. Returns up to 50 corporations with their 法人番号 and lifecycle status. Dynamic pricing: a base fee plus a small per-result fee.

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/32567.json for the price and payment options.
Pay. Call GET https://houjin.agentic-jp.com/search. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, Polygon, Solana, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
