# Lithos

One API to order consults and prescriptions for your patients and have them shipped to their door. Your product submits the request, one of our licensed doctors reviews and signs it, the pharmacy fills it, and order status streams back to you. Refills work the same way. Live in all 50 states. HIPAA-compliant; BAA available.

Built for agentic healthcare — so agents can act, not just talk: a prescription is three API calls, the doctor’s decision comes back on a webhook, and your agent can show the user their order and delivery status.

## What your agent can do

• Register patients — demographics, address, and the telehealth consent timestamp your app captured
• Submit encounters — initial for a new relationship, follow_up for renewals and check-ins — with intake
• Check encounter status and surface the clinician’s decision to the user
• Show order status — pending, processing, completed — and the fulfilling pharmacy
• Register insurance and read prior-authorization status
• Keep care going: follow_up encounters for renewals and dose changes

## Example — refill a user’s finasteride

Say an assistant has built a health profile for its user, and the user asks: “I’m almost out of finasteride — can you refill it?”

POST /v1/oauth2/token      # client credentials → short-lived Bearer token
POST /v1/patients          # create or match the patient (external_id = your user id)
POST /v1/encounters        # encounter_type: follow_up · intake_data: the check-in

# a licensed physician in the patient's state reviews the AI-prepared case

← webhook  encounter.approved    # GET /v1/encounters/{id} → prescription · days_supply
← webhook  order.created         # fulfillment order opened at the pharmacy
← webhook  order.completed       # fulfilled

# agent → user: "Refill approved — your pharmacy has it."

The same loop covers new treatments and dose changes. Your agent stays in the conversation; Lithos handles the doctor, the pharmacy, and the paperwork.

## Who it’s for

• AI assistants and health products whose agents order refills and care for their users
• Med spas and wellness clinics adding prescribing — GLP-1s, hormones, peptides — without hiring a compliance team
• Independent clinicians taking their practice direct while Lithos runs the back office
• DTC health brands launching new categories in weeks, keeping their funnel and patient relationship
• Platforms and marketplaces consolidating a multi-vendor clinical stack into one API

## API

• Base URL: https://api.lithoshealth.com/v1 (sandbox api.sandbox.lithoshealth.com) — REST, JSON; OAuth2 client credentials → short-lived Bearer token
• Resources: patients · encounters · orders · prescriptions · prior_authorizations · insurances · documents · webhooks for every state change
• Docs: docs.lithoshealth.com
• MCP server: @lithos/mcp (early access)
• For LLMs: /llms.txt · /llms-full.txt

## The clinician loop

Every request your agent makes gets a real clinical outcome, because a licensed clinician in the patient’s state reviews and signs it. That’s what makes the rest possible — your agent delivers prescriptions without practicing medicine.

• The treatments physicians may prescribe and the required intake keys are configured per organization; intake_data is validated at the API boundary
• The telehealth consent timestamp is on the patient record before encounters move
• Verdicts, prescriptions, and fulfillment stream back as webhooks your agent can act on
• Every action is timestamped, attributable, and exportable via API

## FAQ

Can our agent request prescriptions?
Yes — initial and follow-up encounters carrying intake. A licensed physician in the patient’s state reviews the AI-prepared case and prescribes, and your agent gets the decision and the order status back over webhooks.

Can our agent show order and delivery status?
Yes. Fulfillment events — order created, processing, completed — stream to your webhooks, so your agent can answer “where’s my medication?” directly.

Who owns the patients and the data?
The brand does. Patients only ever see your brand; patient and operational data is exportable via API at any time.

Do brands need their own clinicians?
No. Lithos operates the clinician network, licensed across all 50 states, with physician oversight built into every program.

How is PHI handled?
Lithos is HIPAA-compliant and signs a BAA. Patient data lives on Lithos with a full, exportable audit trail; you hold only what you choose to keep on your side.
