Whaleshine is built to be bookable by agents. Two endpoints, no API key, JSON in and out. Payment hands off to a Stripe Checkout URL that your user completes themselves. A machine-readable summary also lives at /llms.txt.
No parameters returns the full catalog with pricing rules. With parameters, a priced quote.

}Service keys: wash, washwax, detail, roofinspect, roofreseal, winterize, dewinterize, bearings, generator. Rig keys: tt (travel trailer), fw (fifth wheel), ca (Class A), cb (Class B), cc (Class C). Length is 10 to 60 feet for per-foot services, billed in 5 ft bands at the band ceiling. Always pass zip: some metro areas price higher, and the response includes the market_multiplier applied.
Prices are recomputed server side; the quote is for display. The response is a Stripe Checkout URL. Hand it to your user: the 25 percent deposit paid there completes the booking, and confirmations arrive by text.
