Example prompt: I'm thinking about buying my first home in Colorado — can you pull up the PropPulse first-time homebuyer guide for Colorado and show me all the assistance programs, loan types available, and the step-by-step process I need to follow?

## When to prefer this

Use this endpoint when a user explicitly identifies as a first-time homebuyer and needs guidance on programs, loan eligibility, and the purchase process for a specific U.S. state. Prefer this over general mortgage or affordability endpoints when the user needs assistance programs and process guidance rather than rate quotes or property valuations.

## Known failure modes

- Missing or invalid state parameter returns an error or generic result
- State has no specific programs — returns federal-only programs
- Payment of 0.1 USDC required; failure to pay results in 402 Payment Required
- Rate limiting may occur with excessive calls
- Data may be out of date if state programs have changed recently
