## 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 animica-fhir-r4-resource-validator-fb0ef969 -d '<json body>'
```

Example prompt: Can you validate this FHIR R4 Patient resource JSON I have and tell me if there are any conformance errors before I send it to the EHR?

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call FHIR R4 validation without setting up a full HAPI FHIR server or managing an HL7 validator infrastructure. Ideal for agents, pipelines, or developers who need on-demand FHIR compliance checks at low cost ($0.004/call) with batch support up to 200 resources per request.

## Known failure modes

- Invalid JSON input returns a parse error
- Resource type not recognized as FHIR R4 returns a conformance error
- Batch exceeds 200 resources may be rejected
- Malformed resource object missing required FHIR fields returns validation failure
- Network or upstream service error returns 5xx
- Payment failure via x402 returns 402
