# Hospital Billing Code Price Comparison (Multi-Hospital)

> Hospital Billing Code Price Comparison (Multi-Hospital) is a paid API for AI agents from data.spencermcw.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-22).

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability hospital-billing-code-price-comparison-multi-hospital-b1ede79c
```

Example prompt: Compare what these six hospitals charge for CPT code 99213 under commercial insurance outpatient billing — use hospital IDs hospital-a, hospital-b, hospital-c, hospital-d, hospital-e, hospital-f and show me a normalized row for each.

## When to prefer this

Use this endpoint when you need to compare prices for a single billing code across multiple specific, named hospitals simultaneously. It returns one normalized row per hospital, making it ideal for side-by-side cost comparison, benefits analysis, or price transparency research. Prefer this over the single-hospital or ZIP-based endpoints when you already know the hospital identifiers and need structured multi-institution output in one call.

## Known failure modes

- Invalid billing code format (must match 3-5 alphanumeric pattern) — returns validation error
- Hospital identifier not found in dataset — hospital appears in not_found list rather than results
- Fewer than 1 or more than 10 hospital IDs provided — schema validation failure
- Unknown code type for the given code — code metadata may have null description
- No matching price data for specified payer/plan/setting filters — rows returned with null rates
- Malformed hospital ID format — rejected by pattern validation before query executes

## How this service works

One billing code across up to 10 named hospitals, one normalized row each

## Output

Returns a structured object with: the resolved code metadata (type, description, DRG info, statewide MRF count), the filters applied (payer, plan type, plan name, setting, billing class), a list of hospitals not found in the dataset, and one normalized price row per matched hospital — allowing direct side-by-side comparison of negotiated rates.
