Example prompt: My health insurance claim was denied and I need to appeal it — here's the denial notice and claim details: 'Claim #4821 denied on grounds of medical necessity for MRI procedure on 04/15/2025.' Can you process this and draft a strong appeal response for me?

## When to prefer this

Choose this endpoint when you need to automatically process insurance or medical claim denial information and generate an appeal response or letter. It is particularly useful in healthcare billing automation, patient advocacy workflows, or any agentic pipeline that needs to respond to claim denials at scale without manual drafting.

## Known failure modes

- Empty or malformed 'data' field returns an error or empty response
- Insufficient claim details in input may produce a generic or low-quality appeal
- Payment failure via x402 protocol results in 402 response before processing
- Ambiguous denial reason may lead to incomplete appeal arguments
- Service unavailability returns 5xx error with no appeal output
