Static sample cost estimate (colonoscopy in Connecticut) from the CostKits API. Works with NO API key — use it to verify connectivity and see the response shape.

Estimate what a medical procedure costs in a US state: allowed-amount range (low/median/high), billing components, risk flags, and — if insurance details are given — the patient's expected out-of-pocket. Use resolve_procedure first if the user gave a free-text procedure name. Always present ranges, not single numbers, and cite the returned data_vintage.

Stateless insurance math: given an allowed amount and a plan snapshot (deductible, coinsurance, OOP max), returns exact patient responsibility, plan payment, and the breakdown, plus p25/p75 scenarios. Use when you already have a dollar amount (e.g. from an EOB or a prior estimate).

One call chaining procedure ontology + cost + providers + patient liability. Cheapest way (one metered request) to get the complete picture. Use fields to request a subset; liability requires the plan_* inputs.

Find healthcare providers for a procedure in a US state. Each provider has pricing_status: 'observed' (real negotiated rate from hospital transparency data — prefer these), 'estimated', or 'none'. Set cluster=true for city-level groups with lat/lng.

Public profile for a single provider by 10-digit NPI number: name, specialty, address, entity type.

Fuzzy-match a free-text procedure name ('knee mri', 'gallbladder removal') to a canonical slug with confidence scores. Call this BEFORE estimate tools whenever the user's wording might not be an exact slug.

The full CostKits catalog: 30 procedures with slugs, display names, categories, and CPT codes (paginated).

Structured knowledge about one procedure. aspect='facts' returns LLM-ready billing rules and cost drivers (best for grounding an answer); 'bundle' explains which separate bills to expect (facility, physician, anesthesia...); 'full' returns the complete ontology.

Insurance coverage rules for a procedure/carrier combination. aspect: 'summary' (status + plain English), 'prior-auth', 'cost-sharing' (deductible/coinsurance/ACA preventive), 'frequency' (how often covered, age rules), or 'triggers' (Pro plan: billing events that flip a $0 preventive claim to diagnostic — the highest-signal aspect).

All insurance carrier keys supported by the coverage tools (aetna, cigna, bcbs, medicare, ...). Works on the Free plan — also a good API-key sanity check.

Detect anomalies in medical bill line items (Pro plan): duplicate charges, unbundling, quantity errors, screening-to-diagnostic reclassification. Returns a risk score, flags, and a consumer-language summary. Stateless — send only codes and amounts, never patient identity fields.
