## Verdicts

**Expedia Group Rapid API.** Expedia's lodging inventory with shop, price check, book, change and cancel in one API. Partner application and site review before production, no self-serve keys.

**Soar.** Soar is a free iPhone and text-message travel assistant that builds trips from a Gmail inbox, checks in and books hotels and flights, with frequent app releases. Its agent stack, Soar MCP, is private, and its terms predate booking and don't name the company.

## Before you call either

### Expedia Group Rapid API

1. Build the SHA-512 signature from key, secret and the current epoch seconds in that order, per request
2. Send `Customer-Ip` and the session headers the docs ask for, since fraud checks use them
3. Point everything at test.ean.com until the site review is through; the paths match api.ean.com
4. Follow the `links` in each response rather than building URLs; price check and book links carry tokens
5. Read the `Rate-Limit-Minute-Remaining` and `Rate-Limit-Day-Remaining` headers, since the docs publish no ceilings

### Soar

1. Don't plan to call Soar from another agent. Its MCP server needs private onboarding by the team.
2. Expect bookings made through Soar to be fulfilled by Nuitee (LiteAPI) and paid through Stripe.
