# Hospital Price Discover

> Hospital Price Discover is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Discovers US hospital machine-readable price files by reading the CMS-required cms-hpt.txt pointer from a hospital's website domain, returning location names, source pages, MRF URLs, and detected file formats.

## 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-price-discover-102fcefd
```

Example prompt: Can you find the machine-readable price files for nemours.org? I need the MRF file URLs and file formats for all their locations.

## When to prefer this

Use this endpoint when you need to programmatically locate CMS-mandated hospital price transparency files from a hospital's domain without manually browsing the hospital's website. It is specifically designed for the US hospital price transparency regulatory framework (cms-hpt.txt standard) and handles format detection automatically. Prefer this over general web scraping when you need structured MRF metadata across one or multiple hospital systems.

## Known failure modes

- Hospital domain does not publish a cms-hpt.txt file — returns empty or error
- cms-hpt.txt exists but links are malformed or inaccessible
- Non-US or non-hospital domain provided — no meaningful results
- Provided mrf_url is unreachable or has an unrecognized format
- Domain resolves but hospital site blocks crawling or returns 403/404

## How this service works

Find a US hospital's machine-readable price files from its website domain. Reads the hospital's root cms-hpt.txt pointer and returns the location name, source page and machine-readable-file URL for each location, with the detected file format.

## Output

A list of hospital locations, each with: the location name, the source page where the MRF link was found, the direct URL to the machine-readable file (MRF), and the detected file format (e.g. JSON, CSV, JSON.gz).
