Call it only once the conversation is about one provider; resolve the NPI first via POST /api/pricing/network-status. Relay each `signals[].display` sentence as written. Evidence is never a ranking, and absence of data is never negative evidence. ## OpenAPI ````yaml api-reference/openapi.yaml POST /api/pricing/provider-evidence openapi: 3.1.0 info: title: Arlo Health MCP Server version: 1.0.0 description: | Healthcare infrastructure for AI agents. Everything an agent needs to act in healthcare for its user. ## Overview This server exposes two interfaces: - **MCP** (Model Context Protocol) over streamable HTTP at `/` for AI agents - **REST API** at `/api/*` for bots, skills, and direct HTTP clients Both interfaces use the same tool handlers and authentication. ## Authentication OAuth 2.1 with PKCE. All `/api/*` endpoints require a Bearer token. Discovery endpoints (no auth required): - `/.well-known/oauth-protected-resource` - `/.well-known/oauth-authorization-server` - `/.well-known/mcp.json` (MCP Server Card) ## Service Regions Care is licensed by where the patient is physically located when they request it, so every conversation carries an ISO 3166-2 `region` code. Arlo currently serves California, United States (`US-CA`); an unsupported region is refused with `REGION_NOT_SUPPORTED`, whose payload names the regions Arlo serves at that moment. contact: name: Arlo Health url: https://arlohealth.ai license: name: Proprietary url: https://arlohealth.ai/tos servers: - url: https://mcp.arlohealth.ai description: Production MCP Server security: - oauth2: - openid - profile - email - offline_access tags: - name: Discovery description: MCP and OAuth discovery endpoints (no auth required) - name: Profile description: User profile and patient information - name: Consultations description: Healthcare consultation management - name: Messaging description: Conversation messaging and media - name: Prescriptions description: Prescription orders (read-only; Photon Health fulfills them) - name: Health Records description: The user's connected insurance and health records (US) - name: Care Pricing description: Free price transparency under the user's plan (US) - name: Care Jobs description: >- Real-world care actions Arlo's care team executes after the patient approves (US) - name: Payment description: Billing and pay-per-use payment management - name: Webhooks description: Webhook registration and status paths: /api/pricing/provider-evidence: post: tags: - Care Pricing summary: Get provider evidence description: | Public-data evidence about ONE specific provider by 10-digit NPI: Medicare-derived experience, facility outcome context (facility-level, never the clinician's own outcome), Medicare payment anchors, or an explained absence.
