## 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 fhir-r4-parser-mcp-b5d7f269 -d '<json body>'
```

Example prompt: Can you parse this FHIR R4 bundle string and extract the structured patient and observation data from it?

## When to prefer this

Choose this endpoint when you need to parse or extract structured data from raw FHIR R4 formatted strings, particularly in healthcare interoperability workflows where HL7 FHIR R4 resources need to be decoded programmatically by an AI agent without a local FHIR parser.

## Known failure modes

- Invalid or malformed FHIR R4 string returns a parsing error
- Non-FHIR formatted input may result in an unrecognized format error
- Empty or missing 'data' field returns a validation error
- Unsupported FHIR resource types may return partial or no extraction
- Network timeout on large bundles

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns structured, parsed output derived from the input FHIR R4 data string, including extracted clinical entities such as patient demographics, observations, medications, conditions, or other FHIR resource fields depending on the input resource type.
