Pharmacokinetic simulation for one compound: walks the published model at one dose and…

What it does

Pharmacokinetic simulation for one compound: walks the published model at one dose and cadence and returns the modelled serum curve over the requested horizon plus a 60-day washout tail. Deterministic math over published reference data -- not medical advice, not a prescription, and for relay to a human decision-maker rather than autonomous administration.

Use with an agent

1. Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
2. Inspect. Fetch /resources/39990.json for the price and payment options.
3. Pay. Call GET https://api.doseplot.com/v1/pk/simulate. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
4. 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.
