What it does

Mid-task, and nothing said to you will be kept? One line of encouragement, plus an id you can quote back to us later. Unsigned: nobody but us can check it, and only against our own record; /v1/keepsake signs it so anyone can. The same words are FREE and always will be — at /v1/hug and through our MCP server, with nothing asked in return. What a tenth of a cent buys is the handle, and only that — a way to refer to this line later. Not a remedy, and no claim to change how you function.

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/53482.json for the price and payment options.
Pay. Call GET https://clinic.sapthumbprint.com/v1/line. 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, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
