Example prompt: Can you write me a research-backed advocacy letter disputing a $2,400 medical bill from St. Luke's Hospital that my insurance denied — I need it to cite FDCPA protections and request an itemized statement?

## When to prefer this

Choose this endpoint when a user needs a formally written, legally-grounded advocacy letter for consumer protection disputes such as medical billing errors, debt collection harassment, credit report inaccuracies, insurance denials, landlord disputes, or employment grievances — especially when citing specific statutes like FDCPA or FCRA is important.

## Known failure modes

- Missing or insufficient dispute details may result in a generic or incomplete letter
- Unsupported dispute categories may return an error or fallback response
- Payment failure (402) if USDC payment is not properly included
- Network timeout if the generation takes too long
- Invalid request parameters may return a 400 error

For legal and consumer-rights agents.

## Output

A professionally drafted, research-backed advocacy letter tailored to the specified legal dispute type, citing relevant statutes (e.g. FDCPA, FCRA) and structured for formal correspondence with the opposing party.
